Action of Pepsin on Proteins

Q.

Why humans can't digest cellulose

Q.

How do enzymes affect humans?

Q.

Pepsin digests the whole protein in food.

1. True.

2. False

Q. The enzyme that controls the hydrolysis of proteins into peptides is

1. Amylase
2. Niacin
3. Trypsins
4. Pepsin

Q.

pepsin is converted to pepsinogen right

Q. Heating of the egg white causes

1. Denaturation of vitamins
2. Denaturation of proteins
3. All of the above
4. Denaturation of casein

Q. Which of the following enzymes acts efficiently at pH $2$?

1. Pepsin
2. Steapsin
3. Trypsin
4. Ptyalin

Q.

In the experiment for testing the action of pepsin on egg-white, we concluded that

1. Pepsin can digest protein only in acidic conditions.

2. If acid is added in higher concentration, it can digest protein alone.

3. Boiled pepsin becomes inactive and hence fail to digest protein.

4. Pepsin alone can also digest protein.

Q. If the stomach does not produce HCl, which enzyme will not function?

1. Ptyalin
2. Trypsin
3. Pepsin
4. Amylase
