Which environmental condition would most likely have the least effect on the rate of enzyme controlled hydrolytic reactions in humans?

Which environmental condition would most likely have the least effect on the rate of enzyme controlled hydrolytic reactions in humans?

Environmental condition that would most likely have the LEAST effect on the rate of enzyme controlled hydrolytic reactions in humans is the amount of light present…..

Which of the following is in the correct order for protein digestion?

Which of the following details the correct order in which proteins are digested? Pepsin breaks down peptide bonds in the stomach, then the pancreatic enzymes complete the digestion in the intestines. The pancreatic enzymes break down peptide bonds in the stomach, then chymotrypsin completes the digestion in the liver.

Which enzyme digests proteins?

Of these five components, pepsin is the principal enzyme involved in protein digestion. It breaks down proteins into smaller peptides and amino acids that can be easily absorbed in the small intestine.

Which factor does not alter the rate of an enzyme reaction?

Substrate concentration: Increasing substrate concentration also increases the rate of reaction to a certain point. Once all of the enzymes have bound, any substrate increase will have no effect on the rate of reaction, as the available enzymes will be saturated and working at their maximum rate.

What would interfere most with the ability of an enzyme to catalyze a reaction?

Proteins (most enzymes are proteins) are sensitive to their environment. You have already seen how changing the substrate concentration and the temperature can affect the efficiency of an enzyme’s ability to catalyze a chemical reaction.

Why does pH affect enzyme rate?

The effect of pH Enzymes are also sensitive to pH . Changing the pH of its surroundings will also change the shape of the active site of an enzyme. This contributes to the folding of the enzyme molecule, its shape, and the shape of the active site. Changing the pH will affect the charges on the amino acid molecules.

What’s the correct order of digestion?

The main organs that make up the digestive system (in order of their function) are the mouth, esophagus, stomach, small intestine, large intestine, rectum and anus.

What is the last step in protein digestion?

Proteins that aren’t fully digested in the small intestine pass into the large intestine and are eventually excreted in the feces. Recall from the last page that plant-based proteins are a bit less digestible than animal proteins, because some proteins are bound in plant cell walls.

Which of the following is not a protein digesting enzyme?

pepsin secreted by the stomach and trypsin and chymotrypsin secreted by the pancreas, break down food proteins into polypeptides that are then broken down by various exopeptidases and dipeptidases into amino acids. Hence, Lipase enzymes are not useful in the digestion of proteins. So, the correct answer is ‘Lipase’.

Which is the end product of protein digestion?

amino acids
The end product of protein must be broken down into amino acids. So, the correct answer is ‘Amino acids’.

What are the factors that affect the digestion of protein?

These factors include: Concentration levels of the enzyme pepsin. How much protein is present at once. The acid levels of the food and stomach (this can be diluted with water consumption) Antacids or other digestion inhibitors.

How does the amount of protein affect metabolism?

It has long been recognized that numerous dietary parameters, such as the amount and type of protein and nonprotein energy sources, affect protein metabolism. More recently, we demonstrated that the protein digestion rate is an independent factor regulating postprandial protein gain.

How much protein can the body digest at a time?

When one is serious about gaining muscle mass, they often look to the amount of protein they are consuming as a way to facilitate muscle growth. The general rule a lot of people follow is that the body can only digest 30g of protein at a time. This is not true.

Which is better for protein digestion WP or CAS?

Our preliminary results suggest that added nonprotein energy sources to CAS and WP attenuated the differences in both the protein digestion rate and protein gain. Finally, and in contrast to young subjects, a “fast” protein may be more beneficial than a “slow” one in elderly subjects, to limit body protein loss.
