Q. How many ATP molecules are produced

during aerobic respiration of one molecule of glucose?

 

A. During aerobic respiration,

complete oxidation of one glucose molecule

produces 38 ATP molecules.

Aerobic respiration involves glycolysis,

link reaction (oxidative decarboxylation of pyruvate),

Krebs cycle and oxidative phosphorylation.

 

[ChatGPT]

During aerobic respiration of one molecule of glucose, a total of 36 to 38 ATP molecules are produced, depending on the source of information and the specific conditions under which the process occurs. This is because the complete oxidation of glucose via aerobic respiration involves a series of interconnected metabolic pathways, including glycolysis, the citric acid cycle, and oxidative phosphorylation, which collectively generate a large amount of energy in the form of ATP.

Q. What is the total number of ATP molecules that can be produced

from the complete oxidation of one glucose molecule?

 

A. Theoretically, complete oxidation of glucose molecule

yield 38 ATP molecules, but according to newer sources,

it is only 30 to 32 ATP molecules.

 

[ChatGPT]

The total number of ATP molecules that can be produced from the complete oxidation of one glucose molecule via aerobic respiration is between 36 to 38 ATP molecules. This process involves the breakdown of glucose through a series of metabolic pathways, including glycolysis, the citric acid cycle, and oxidative phosphorylation, which generate energy in the form of ATP. The exact number of ATP molecules produced can vary depending on the specific conditions and the source of information. However, the range of 36 to 38 ATP molecules is a commonly accepted value for the net ATP yield from the complete oxidation of one glucose molecule via aerobic respiration in eukaryotic cells.
