Answer 2

Answer:

14 ATP are produced through ETS from two molecules of acetyl Co-A in aerobic respiration.

Explanation:

• Aerobic cellular respiration is of three parts, namely glycolysis, the Krebs (citric acid) cycle, and oxidative phosphorylation.
• During glycolysis, glucose will metabolise into two molecules of pyruvate, with an output of ATP and nicotinamide adenine dinucleotide (NADH).
• Each pyruvate oxidises forming acetyl CoA and a molecule of NADH and CO₂.
• The acetyl CoA is used in the Krebs cycle,      
• This is a chain of chemical reactions that produce CO₂, NADH, ATP, and flavin adenine dinucleotide (FADH2).
• During the final step, three NADH, 1 FADH2 are used in oxidative phosphorylation, to produce water and ATP.

Working:

• 1 molecule of 3-phosphoglycerate during glycolysis, 1 NADH is formed from the pyruvate forming 2 acetyl CoA.

• 1 molecule of acetyl CoA that enters the Kreb's (citric acid) cycle will form 3NADH and 1FADH2.
• ADH and FADH2 will take part in ETS, forming 14 ATP.
• Total number of NADH = 4
• 1NADH forms 3 ATP.
• ∴ 4 NADH = 4×3≈ 12 ATP.
• 1 FADH forms 2 ATP.
• ∴ The total number of ATP formed is 14.

Hence, 14 ATP are formed through ETS is 14.
