When oxygen is scarce, cellular pyruvic acid will be converted to
A) glucose.
B) ATP.
C) lactic acid.
D) fatty acids.

Question

Quizplus · Accepted Answer

When there is not enough oxygen available for cellular respiration to continue, the body must switch to an alternative pathway for energy production known as fermentation. One type of fermentation is called lactic acid fermentation, which converts pyruvic acid to lactic acid. This process allows cells to continue producing ATP, but at a less efficient rate. Therefore, the correct answer is C, lactic acid.
