Question

Assertion (A):In anaerobic respiration, one of the end product is alcohol
Reason (R): There is an incomplete breakdown of gulucose
a) both A and R true and R is the correct explanation of A
b) both A and R are true and R is not the correct explanation of A
c) A true and R is false
d) A is false and R is true ​

Answer 1

The correct option is- a) both A and R true and R is the correct explanation of A.

What is anaerobic respiration?

• The anaerobic respiration takes place in the absence of oxygen where the partial breakdown of glucose results in the formation of lactic acid or ethanol (alcohol). Carbon dioxide is released in this process.
• Due to an incomplete breakdown of glucose, a very little amount of energy is released.

Two types of anaerobic respiration are:

1. Lactic acid fermentation- In which lactic acid is the end product and sometimes, it takes place in the muscle cells of humans.
2. Alcoholic fermentation- In which alcohol is the end product and it occurs in yeasts.
