Answer

Explanation:

Step1: Recall ATP - production in glycolysis

Glycolysis produces 2 net ATP and 2 NADH per glucose. Each NADH can produce about 2 - 2.5 ATP in the electron - transport chain. So, from glycolysis, total ATP is approximately 2+(2×2.5)=7 ATP.

Step2: Recall ATP - production in pyruvate oxidation

Each pyruvate (2 pyruvates from 1 glucose) is oxidized to acetyl - CoA, producing 1 NADH per pyruvate. So, 2 NADH are produced, which can generate about 2×2.5 = 5 ATP.

Step3: Recall ATP - production in the Krebs cycle

The Krebs cycle produces 2 ATP, 6 NADH, and 2 FADH₂ per glucose. Each NADH produces about 2.5 ATP and each FADH₂ produces about 1.5 ATP. So, from the Krebs cycle, ATP production is 2+(6×2.5)+(2×1.5)=2 + 15+3 = 20 ATP.

Step4: Calculate total ATP

Adding up the ATP from glycolysis, pyruvate oxidation, and the Krebs cycle, we get 7 + 5+20=32 ATP on average. So, the range is around 34 - 36 ATP considering some minor variations in the efficiency of the electron - transport chain.
