Question

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

• A. Pepsin can digest protein only in acidic conditions.
• B. If acid is added in higher concentration, it can digest protein alone.
• C. Boiled pepsin becomes inactive and hence fail to digest protein.
• D. Pepsin alone can also digest protein.

Answer 1

Answer: (A), (C)

The correct options are
A

Pepsin can digest protein only in acidic conditions.

C

Boiled pepsin becomes inactive and hence fail to digest protein.

Pepsin alone or acid alone cannot digest proteins. They need to be present together to convert proteins into peptides and digest the same.
