A) one time.
B) two times.
C) three times.
D) four times.
E) six times.
Citric Acid Cycle
A series of chemical reactions used by all aerobic organisms to generate energy through the oxidation of acetate derived from carbohydrates, fats, and proteins into carbon dioxide.
Glucose
serves as a primary source of energy in most organisms, critical for cellular respiration and metabolic processes.
Turn
In a molecular context, a turn refers to a type of secondary structure in proteins where the chain makes a sharp change in direction.

Final Answer :
B
Explanation :
For the complete respiration of one molecule of glucose, the citric acid cycle must turn a total of two times. This is because one molecule of glucose, through glycolysis and subsequent reactions, produces two molecules of acetyl-CoA, each of which enters the citric acid cycle separately.
