Enzymes and their substrates are sometimes referred to as the lock and key model. what does this tell you about enzyme behavior

1 answer:

4 0

This tells us about the specificity of enzymes.

Since in the lock and key model, the lock is only suitable for one key to unlock, only one pattern of key is able to do that, so, to compare it with enzymes, it means that the active site of enzyme is only suitable to bind one type of substrate to it, not other substrates.

We call this property of enzyme the specificity of enzyme. If the active site of an enzyme is changed or loss its three dimensional patterns, it can no longer function as a biological catalysts to speed up chemical reactions.

Select the correct statements about glycolysis. a) Major products of glycolysis include pyruvate, ATP , and NADH . b) Glycolysis

dalvyx [7]

Answer:

a). Major products of glycolysis include pyruvate, ATP , and NADH

b) Glycolysis is the process by which glucose is converted to two molecules of pyruvate.

Explanation:

Glycolysis is a process in which a glucose molecule is broken down into two molecules of pyruvate. The process of glycolysis occurs without oxygen therefore it can occur in both aerobes and anaerobes.

The process of glycolysis occurs in the cytoplasm of the cell and the products of glycolysis are 2 molecules of pyruvate, 2ATP, and 2 NADH molecule. Then the pyruvate molecule gets into mitochondria which it's complete oxidation takes place. Therefore the right answer is a and b.

Tortoise shell cats, like the one shown above, are always femaleWhat scientific phenomenon explains the color pattern of

8_murik_8 [283]

Tortoise shell cats can be explained as the offspring from a incomplete dominance cross. Incomplete dominance gives rise to an intermediate phenotype.

The scientific phenomenon that explains the color pattern is X-linked incomplete dominance.

As stated earlier, the tortoise shell colour is as a result of incomplete dominance but as it exists only in females, the inheritance is X linked.
This means the tortoise shell colour is inherited in the heterozygous condition as females have two X (XX) and males (XY) can only be either of the parent's true breeding genotype.

Researchers are studying the abnormal activity of kinases in relation to cancer. Theoretically, how might researchers use signal

myrzilka [38]

Answer:

I am pretty sure that the answer is A.

Explanation:

Protein kinases regulate the cell cycle by giving the "go-ahead" or "stop" signal at checkpoints in the cycle. A mutation/disruption in the protein kinases can result in it not doing its job properly. As a result, it can give the 'go-ahead' signal to all cells (mutated or not) to continue through the cell cycle. A distrupted kinase will infleunce the enviornment for a cancer cell as the cancer cell can continue to divide continuously.

I do not think the answer is D because G-couped receptirs are not involed in the regulation of the cell cycle. Additionally, I do not think the answer is C since the production of cAMP (a secondary messgenger amplifies transduction signals; this doesn't have anything to do with cancer?) Finally, between A and B I know that a direct result of cancer is due to a distruption in either protien kinases or growth factors (not in the answer choices). Since one of the factors that leads to cancer is present in answer choice A, I think that is the one. However, this is just my reasoning, I am not 100% sure!
