Which of the following metabolic processes produces the most ATP?
Question
Which of the following metabolic processes produces the most ATP?
Solution
The metabolic process that produces the most ATP is Oxidative Phosphorylation. Here's a step-by-step explanation:
-
Glycolysis: This is the first step of glucose metabolism, which occurs in the cytoplasm of the cell. One glucose molecule is broken down into two molecules of pyruvate, producing a net gain of 2 ATP molecules.
-
Pyruvate Decarboxylation: Each pyruvate is then transported into the mitochondria and converted into Acetyl CoA, producing 1 NADH each (which can later be used to produce ATP).
-
Krebs Cycle (Citric Acid Cycle): Each Acetyl CoA enters the Krebs cycle. For each round of the cycle, 1 ATP, 3 NADH, and 1 FADH2 are produced.
-
Oxidative Phosphorylation (Electron Transport Chain and Chemiosmosis): This is where the majority of ATP is produced. The NADH and FADH2 produced in the previous steps are used here. Each NADH can produce approximately 2.5 ATP, and each FADH2 can produce approximately 1.5 ATP.
So, the process that produces the most ATP is Oxidative Phosphorylation.
