What is the enzyme rennin useful for? A) making cheese B) making bread C) making wine and beer D) tenderizing beef E) digestion of starch Which of the following colors represents a positive lodine test? A) cloudy white B) red C) green D) blue-black E) clear Activation energy is the amount of energy required to stop enzyme activity. A) True B) False In the enzyme equation to the right, starch is the: starch amylase/(enzyme) product A) enzyme-substrate complex B) inhibitor C) activation energy D) catalyst E) substrate

Solution

Answer 7) ‘A’ and ‘D’

Rennin is also known as Chymosin. It is used for converting milk into curd. It is largely used in cheese-making industry for conversion of milk. It can also be used for tenderizing beef.

Answer 8) D

When iodine is applied on starch, then a blue-black color appears. This is called as a positive iodine test.

Answer 9) False

The correct statement should be: “Activation energy is the amount of energy used to start enzyme activity”.

Answer 10) E

Starch is the substrate. Enzyme, amylase is acting on to this substrate, to convert it into product (glucose).
