What is unique about active sites?
A: active sites provide cells with energy.
B: active sites are specific to certain substrates (reactants).
C: active sites store the genetic information of cells.
The Unique feature of Active sites is that active sites are specific to certain substrates (reactants)
Active sites are specific regions of an enzyme where substrate molecules bind in other to bring about a chemical reaction.
The active site is made up of amino acid which forms temporary bonds with the substrate otherwise known as the binding site and the residues which brings about a reaction of that substrate.
Active sites are specific to certain substrates (reactants). Therefore, option (B) is correct.
Active sites are vital to enzymes, proteins that aid biological processes. They have a distinctive form that matches their substrate molecules. This specificity allows only particular substrates to bind to and interact with the active site, catalysing processes. This is called the "lock and key" or "induced fit" model.
Enzymes' catalytic action depends on active sites. A substrate attaches to an enzyme's active site and changes conformation, lowering the reaction's activation energy. This speeds up the reaction. After the reaction, the products are released and the enzyme's active site can bind to another substrate. Therefore, option (B) is correct.

3. ADP + Pi → ATP is best classified as which type of reaction?
Answer:
Hi Motomasa, you are correct that there is a bit of a misrepresentation, or at least a glossing-over, in the standard description of the function of ATP. The "energy-storing" capacity of ATP is NOT in the forming and breaking of the covalent phosphate to phosphate bonds. ATP -> ADP releases energy by two mechanisms. First because the process of hydrolysing the y-phosphate (the terminal phosphate) releases energy. And second because ATP and ADP are maintained out of equilibrium in cells. The action of utilizing an ATP brings the system closer to equilibrium, which releases energy.
There is a required energy input to break the phosphate to phosphate bond. This is the activation energy. However, the energy released upon hydrolysis and moving the system towards equilibrium are of greater magnitude than the activation energy input. I hope this helps!

What do the terms stage and grade mean in the context of cancer?
What current treatments exist for cancer?
What treatments are on the horizon?
What are the challenges of treating or curing cancer?
Answer:
- Cancer isn't a single disease. The term cancer encompasses more than 200 diseases all characterized by the uncontrolled proliferation of cells.
- Cancer cells also fail to undergo programmed cell death, or apoptosis, under conditions when normal cells would (e.g., due to DNA damage). In addition, emerging research shows that cancer cells may undergo metabolic changes that support increased cell growth and division 5start superscript, 5, end superscript.
Genetic Changes and Cancer
Genes carry the instructions to make proteins, which do much of the work in our cells. Certain gene changes can cause cells to evade normal growth controls and become cancer. For example, some cancer-causing gene changes increase production of a protein that makes cells grow.
- People who have certain jobs such as; painting, construction, pesticide and petroleum workers have an increased risk of cancer. Many studies have shown that exposure to asbestos, benzene, benzidine, cadmium, nickel, arsenic, radon and vinyl chloride in the workplace can cause cancer.
- Metastatic cancer causes most cancer deaths, but exactly why it is so difficult to treat is not precisely understood. Metastatic tumors often acquire additional genetic changes from those in the primary tumors that spawned them, and these genetic characteristics may cause them to resist standard treatments.
- Treating cancer is further complicated due to the lifestyle and attitude of patients, the different physiology of people and the rate their bodies will metabolise drugs, the blood supply to the tumour affecting the drug getting into the tumour, the tumour physiology and the fact that the tumour can continue to change.
- The stage of a cancer describes the size of a tumour and how far it has spread from where it originated. The grade describes the appearance of the cancerous cells.
- Cancer treatment options include:
Surgery. The goal of surgery is to remove the cancer or as much of the cancer as possible.
Chemotherapy. Chemotherapy uses drugs to kill cancer cells.

What is DNA replication?The biological process of creating two identical copies of DNA from a single original DNA molecule is known as DNA replication. All living things replicate their DNA, which is the most crucial component of biological heredity.
There are two stages to the beginning of the DNA replication process. To begin, a protein known as an initiator unwinds a portion of the DNA double helix along a very short region. After then, a protein that is known as helicase attaches itself to the DNA strands and breaks the hydrogen bonds that are present between the bases. This results in the two strands of DNA being separated.
When two single strands of DNA are cut apart, a 'Y'-shaped structure is produced that is referred to as a replication 'fork.'
