Biomolecules Question 176
Question: Accumulation of which of the following molecules in the muscles occurs as a result of vigorous exercise-
Options:
A) Glycogen
B) Glucose
C) Pyruvic acid
D) L-lactic acid
Show Answer
Answer:
Correct Answer: D
Solution:
[d] $ \underset{\begin{smallmatrix} storedin \\ theformof\downarrow \\ Glycogen \end{smallmatrix}}{\mathop{Glucose}}\xrightarrow[\begin{smallmatrix} (doesnotneed \\ oxygen;need \\ onlyenzymes) \end{smallmatrix}]{{}} $
$ \underset{Lacticacid}{\mathop{\underset{\downarrow }{\mathop{Pyruvicacid}}}}\xrightarrow{O_2}CO_2+H_2O $
During vigorous exercise sufficient oxygen is not available to meet the energy demand so, energy is derived through conversion of pyruvic acid to lactic acid.
