Calcium, IP3, and cyclic AMP are all small molecules that can be found inside most cells, yet they are known to be important second messengers that can increase or decrease in response to a wide variety of signals. However, each signal often produces completely different responses. Give an example of this phenomenon, and explain how such responses occur.

Answers

Answer 1

Answer:

they are second messenger molecules capable of triggering different signaling pathways

Explanation:

Second messenger molecules are intracellular signaling molecules that trigger different cellular responses. Examples of second messengers include Calcium ions (Ca2+), Inositol trisphosphate (IP3), and cyclic AMP (cAMP). Secondary messengers may be activated by different cellular responses, for example, cyclases that synthesize cAMP or by opening calcium ion (Ca2+) channels. For example, cAMP signaling is able to activate kinase enzymes that perform phosphorylation and interact with other effector molecules to mediate different biological functions (for example, regulation of glycogen and sugar metabolism). On the other hand, Ca2+ signaling is required for muscle contraction, neurotransmitter release, etc. Ca2+ signaling is known to exert allosteric control over enzymes and other types of proteins.

All cells contain two proteins called actin and myosin? True or false

Answers

Answer: i think its true

Explanation:

True  that all eukaryotic cell i.e. muscle cells. contains actin and myosin protein .

What are actin and myosin protein?Actin filaments are responsible for a variety of cell motions, generally in conjunction with myosin. Myosin is a molecular motor prototype—a protein that transfers chemical energy in the form of ATP into mechanical energy, allowing it to generate force and movement. Muscle contraction is the most noticeable type of such movement, and it has served as a model for studying actin-myosin interactions and myosin motor activity. Actin and myosin interactions, on the other hand, are essential for not just muscle contraction but also a range of non muscle cell motions, including cell division, making them important in cell biology.Actin is a protein found in all eukaryotic cells. Actin filaments move along filaments of another protein called myosin to cause cells to contract. It was initially found in skeletal muscle. Actin filaments are less structured in non muscle cells, and myosin is considerably less prominent.

Hence, the given statement is true.

c. It contains uracil, which functions in protein synthesis
d. It consists of alternating phosphates groups and deoxyribose molecules

Answers

Answer:

d. It consists of alternating phosphates groups and deoxyribose molecules

Explanation:

The statement above best describes a portion of the molecule that is represented here.

Actually, the molecule represented here is the Deoxyribonucleic acid (DNA). The molecule is composed of two polynucleotide. The DNA carries genetic properties that lead to growth, development, reproduction and functioning of organisms. The phosphate group and deoxyribose molecule are found attached to the DNA. The phosphate group is also found in RNA and in ATP. The deoxyribose is known to be a five-carbon sugar molecule which helps to form the phosphate backbone of DNA molecules.

The given molecule is consists of alternating deoxyribose molecules and phosphates groups.

DNA:

It is the biomolecule that is made up of nucleotide polymers. Nucleotide are made up deoxiribose sugar, phosphate, and nitrogenous bases.

In a DNA strand one nucleotide link with another by the phosphodiester bond in which 3' OH of pentose sugar bond with 5' OH of phosphate.

A. Carbohydrates provide an additional source for amino acids.
B.Carbohydrates provide an immediate energy source
C. Carbohydrates provide permanent storage for genetic information.
D.Carbohydrates provide storage for water molecules​

Answers

Answer:

[tex]\boxed {\boxed {\sf B. \ Carbohydrates \ provide \ an \ immediate \ energy \ source}}[/tex]

Explanation:

Carbohydrates are important because they provide the body with energy. It's essential to consume the correct amount of carbohydrates for your body, but make sure they are healthy (examples: whole grain, squash, sweet potatoes, beans)

Carbohydrates are easy for the body to break down. The body will digest these first into simple sugars, like glucose. The glucose is then used in cellular respiration to produce ATP or energy.

Therefore, carbohydrates can quickly provide energy for the body. The best answer choice is B.

Answer:

Carbohydrates provide energy to organisms.

Explanation:

I'm 100% sure because Carbohydrates can also be defined chemically as neutral compounds of carbon, hydrogen and oxygen. Carbohydrates come in simple forms such as sugars and in complex forms such as starches and fiber. The body breaks down most sugars and starches into glucose, a simple sugar that the body can use to feed its cells

Answers

The same way bacteria becomes resistant to antibiotics.

Mutations in their DNA.

When an organism or insect develops a mechanism for the removal of the pesticide compound is known as pesticide resistance.

What is pesticide resistance?

The organism or insects develop mechanisms such as the alternation of the binding site of the compound present in the pesticide leading to the development of resistance against the used pesticides. The development of resistance against the pesticide is a slow process, it takes time. The usage of pesticides becomes a failure if organisms develop resistance.

The frequent use of pesticide and insecticides cause changes in the genetic material of the organisms. They help in the development of enzymes and changes in the binding sites. These changes are passed on to the next generation of the organism, which makes the entire population resistant to the particular pesticide and insecticide.

The use of the chemicals should be monitored. Only use when required with rotation.
