Question
Which of the following produced the most ATP?
- Group of answer choices
- Aerobic Respiration
- Anaerobic Respiration
- Fermentation
- Glycolysis
Solution
The process that produces the most ATP is Aerobic Respiration. Here's a step-by-step breakdown:
-
Glycolysis: This is the first step of glucose metabolism and occurs in the cytoplasm of the cell. It produces a net gain of 2 ATP molecules.
-
Anaerobic Respiration/Fermentation: If oxygen is not present, cells can undergo either anaerobic respiration or fermentation to produce ATP. Both of these processes also occur in the cytoplasm and produce a net gain of 2 ATP molecules.
-
Aerobic Respiration: If oxygen is present, cells can undergo aerobic respiration, which includes the Krebs cycle and the electron transport chain. This process occurs in the mitochondria and produces a net gain of approximately 34-36 ATP molecules.
So, among the options given, Aerobic Respiration produces the most ATP.
