When Glucose is Metabolized in the Absence of Oxygen, One

Question

When glucose is metabolized in the absence of oxygen, one of the end products is
A) pyruvic acid.
B) ketone bodies.
C) lactic acid.
D) citric acid.
E) nitric acid.

Accepted Answer

When glucose is metabolized in the absence of oxygen (anaerobic conditions), the process is called fermentation. One of the end products of fermentation in animals is lactic acid, while in yeast, ethanol is produced. Pyruvic acid is an intermediate product in both aerobic (with oxygen) and anaerobic respiration. Ketone bodies and citric acid are not typically produced in anaerobic metabolism, and nitric acid is not a product of glucose metabolism.
