Respiratory Quotient (RQ) is one in case of
View answer and explanation
Correct option: C
Carbohydrates
Option C (Carbohydrates) is correct because carbohydrates have a respiratory quotient (RQ) of 1, meaning the volume of produced equals the volume of consumed.

Select the correct statement(s)
(a) The substrate used in protoplasmic respiration does not contain nitrogen.
(b) Facultative anaerobes respire only in the absence of oxygen
(c) Substrate level ATP synthesis also occurs during glycolysis
(d) The ultimate product of glycolysis is pyruvic acid
(a) The substrate used in protoplasmic respiration does not contain nitrogen.
(b) Facultative anaerobes respire only in the absence of oxygen
(c) Substrate level ATP synthesis also occurs during glycolysis
(d) The ultimate product of glycolysis is pyruvic acid
View answer and explanation
Correct option: C
(c) and (d)
Option C ((c) and (d)) is correct because substrate-level ATP synthesis occurs during glycolysis, and the ultimate product of glycolysis is pyruvic acid.

In hurdle race, which of the following is accumulated in the leg muscle?
View answer and explanation
Correct option: B
Glycolysis
Option C (Lactate) is correct because during intense exercise like a hurdle race, the muscles may not receive enough oxygen, leading to anaerobic respiration and the accumulation of lactate (lactic acid).

View answer and explanation
Correct option: A
Lactic acid
Option A (Lactic acid) is correct because during intense exercise, when oxygen is limited, pyruvic acid is reduced to lactic acid.
