Which of the following results from the incomplete breakdown of glucose that occurs under anaerobic conditions?
Hydrochloric acid
Ketotic acid
Carbonic acid
Lactic acid
The Correct Answer is D
A. Hydrochloric acid is a strong acid produced in the stomach to aid in digestion, not a byproduct of glucose breakdown.
B. Ketotic acid is produced in conditions where fat metabolism predominates, especially during ketosis, not during anaerobic glucose breakdown.
C. Carbonic acid forms when carbon dioxide dissolves in water and is not related to glucose metabolism.
D. Lactic acid is produced during anaerobic respiration when glucose is broken down without sufficient oxygen. This occurs in muscles during intense exercise, leading to the accumulation of lactic acid, which causes the sensation of muscle fatigue. This is the correct answer.
