Answer & Solution

Answer: (Detailed Solution Below)

Option C: Both 1 and 2

Detailed Solution:

The correct answer is “Both 1 and 2”.
Enzymes are biocatalysts, which means they are proteins that catalyze (speed up) chemical reactions in living organisms.

Enzymes can act at the site where they are produced, but they can also be transported to other locations where they perform their function.

Additionally, enzymes can be released into the environment outside of the organism, such as digestive enzymes in the gut.
