What will happen to enzyme if active site loses its shape?
The substrate's affinity for binding will decline, causing the enzyme to either complete the reaction at a slower rate than usual or not at all, depending on how much the active site has changed.
Proteins known as enzymes serve as biological catalysts and speed up chemical reactions. Substrates are the substances that interact with enzymes, and the enzyme changes the substrates into products, which are other molecules. Enzyme catalysis is required for the bulk of cellular metabolic processes to proceed at speeds quick enough to support life. An enzyme is required for each step in the catalysis of metabolic processes. It is acknowledged in the fields of pseudoenzyme analysis, enzymeology, and the study of enzymes that some enzymes have evolved without the capacity to perform biological catalysis. Their strange "pseudocatalytic" abilities and amino acid sequences often reflect this.

What happens when CO2 increases in the ocean?
More carbon dioxide is evaporating into the ocean as a result of human-driven increases in atmospheric carbon dioxide concentrations. Currently, the ocean has an average pH of 8.1, which is basic (or alkaline), but when more CO2 is absorbed, the pH drops and the ocean becoming more acidic.
Ocean acidificationCarbon dioxide dissolves in seawater as it reaches the ocean. It first creates carbonic acid. The carbonic acid then "dissociates," or separates, into bicarbonate ions and hydrogen ions. Ocean acidification is caused by an increase in hydrogen ion concentration and a decrease in carbonate ions as a result of increasing CO2 absorption.
Carbonate ions are necessary for the growth of the shells and thriving of clams, mussels, crabs, corals, and other marine life.

Is the claim, "Despite not being a plant, you get your energy from the sun." accurate?
Write a paragraph explaining your reasoning.
Answer:
Yes (kind of), because even though we do not use the sun as directly as say plants, we still rely on the sun on a daily basis, however we don't necessarily get our energy from it, like plants do.
The sun produces light as well as heat, also known as solar energy. This makes it possible for life to exist on Earth, and we can use solar energy to power a wide variety of useful things, however sun/solar energy is not the only way to get electricity.
As we know, plants need sunlight to grow, although humans don't grow by being exposed to sunlight, sunlight helps grow plants which animals, including humans, need for food as well as oxygen they produce.
Most livestock we eat, cows for example, need plants to survive and many people eat meat, and even if you don't you'd eat plants which, once again, need sunlight to grow. Also, without heat from the sun, Earth would freeze.
OVERALL...
It's kind of like a chain, we get our energy from things that get their energy directly from sunlight. A short answer would be yes, but it's not quite as simple as that.
I hope this helps, hopefully you can use it to formulate an answer of some sort.

Sex-related disorders are handed down through generations via the X or Y chromosome. The X and Y chromosomes are sex chromosomes. A heterozygous genotype is defined as an organism with one dominant allele and one recessive allele.
Dominant inheritance occurs when one parent's defective gene causes disease while the corresponding gene from the other parent is normal. The aberrant gene takes precedence.
However, in recessive inheritance, both matching genes must be faulty for illness to occur. If only one of the two genes is faulty, the illness does not arise or is mild. A carrier is someone who has one faulty gene but no symptoms. Carriers' offspring may inherit faulty genes.

Notice the two possible arrangements of chromo-somes in late prophase I. Considering what you know about DNA replication and meiosis, is either arrangement equally likely during the formation of tetrads in late prophase I
Yes, both arrangements of chromosomes in late prophase I are equally likely during the formation of tetrads. This is because, during meiosis, the homologous chromosomes replicate and then line up in pairs, known as tetrads.
During this process, the chromosomes can line up in any order, as long as the homologous chromosomes are paired together. Since the two arrangements of chromosomes in late prophase I consist of homologous chromosomes, they are both equally likely during the formation of tetrads.
Furthermore, during meiosis, the homologous chromosomes randomly separate and move to opposite sides of the cell in anaphase I, so the order of the chromosomes in late prophase I will not affect the outcome of meiosis.

As organs and organ systems continue to develop in this embryo, the eyes will contain clear, transparent lenses. How does a single group of cells differentiate to produce both the transparent lens cells as well as all the other specialized cells in the completed organism
Throughout embryonic development, a single group of cells, known as the ectoderm, differentiates to form a variety of specialized cells that make up the body of a completed organism.
One example of this is the development of the eyes, which contain clear, transparent lens cells. In order to understand how a single group of cells can differentiate to form such diverse components, it is important to understand the underlying cellular processes that drive this differentiation.
First, the ectoderm of the embryo undergoes a process known as gastrulation. During this process, the ectoderm begins to fold and divide, producing three distinct layers of cells known as the endoderm, mesoderm, and ectoderm.
As the cells differentiate, they begin to express different proteins on their surfaces which become the basis for further cell-to-cell interactions and signaling. This process is known as inductive signaling and is responsible for the development of the specialized cells in the embryo.
The inductive signaling process is responsible for the formation of the transparent lens cells in the eye. As the ectoderm begins to differentiate, certain cells in the mesoderm will receive signals from the ectoderm to begin the process of lens formation. The lens cells then produce proteins that induce the formation of other specialized cells in the eye, such as the cornea and the iris.

describe the process of urea formation
Urea is formed through a process called urea synthesis, which occurs in the liver. During this process, the liver combines two molecules of ammonia with one molecule of carbon dioxide to form urea. This reaction is catalyzed by the enzyme urea synthase and requires the presence of energy in the form of ATP. The urea synthesis process helps to remove excess nitrogen from the body, as ammonia is a toxic waste product that is produced during the breakdown of proteins. The urea is then excreted from the body through the urine
Urea is synthesized in the body of many organisms as part of the urea cycle, either from the oxidation of amino acids or from ammonia. In this cycle, amino groups donated by ammonia and L-aspartate are converted to urea, while L-ornithine, citrulline, L-argininosuccinate, and L-arginine act as intermediates.

what enzyme can proof-read the dna molecule, minimizing the mistakes made during the process of dna replication?
The enzyme that can proof-read the DNA molecule during the process of DNA replication is called DNA polymerase. DNA polymerase is responsible for adding nucleotides to the growing strand of DNA during replication.
Some DNA polymerases, such as DNA polymerase III and DNA polymerase I, have a proofreading exonuclease activity that allows them to remove any nucleotides that are not correctly paired with the template strand during replication.
The proofreading exonuclease activity of DNA polymerase works by recognizing mismatches between the nucleotides that have been added to the growing strand and the template strand. When a mismatch is detected, the exonuclease activity of the enzyme removes the incorrectly paired nucleotide, allowing the polymerase to add the correct nucleotide in its place.
This proofreading activity increases the accuracy of DNA replication, reducing the number of errors made during replication to approximately 1 in 10^5 nucleotides.

Cellular Communication and the Cell Cycle FRQ:
a) Low extracellular pH activates TRPV1 through the binding of H + ions to TRPV1. Describe the properties, including the location, of the site of TRPV1 that allow H+ ions to bind. Describe the specific location in the cell where ATF3 protein is produced.
b) The pGoG protein is known to block the G1 to S transition in the cell cycle. Explain why this prevents mitosis from happening in the cell
Specifically, in sensory neurons, the plasma membrane of cells contains the cation channel protein TRPV1. Heat and low extracellular pH are only two of the many triggers that might cause it to become active.
The protein TRPV1 undergoes a conformational shift in response to the adsorption of H+ ions, opening the ion channel and allowing calcium ions to enter the cell. The subsequent signaling pathways that result in the perception of pain are activated by this calcium ion inflow.
ATF3 protein is exclusively synthesized in the cytoplasm of the cell, more particularly in the nucleus, where it is transcribed from the ATF3 gene.
The pGoG protein is known to block the G1 to S transition in the cell cycle by inhibiting the activity of the cyclin-dependent kinase (CDK) that is responsible for initiating DNA replication. This prevents mitosis from happening in the cell because, without DNA replication, the cell cannot divide.
Additionally, the pGoG protein also promotes the activity of the tumor protein p53 which is also known as the "guardian of the genome" and helps to prevent DNA damage and cell mutations, when it is activated it can stop the cell cycle and prevent mitosis from happening.
