Question

Complete the following flowchart.
Carbohydrates enter $\to$______(a)_____$\to$Pyruvic acid$\to$Acetyl-CoA enters $\to$____(b)____$\to$Carbon dioxide+ Water+ Energy

• A. (a) Glycolysis, (b) Kreb's Cycle
• B. (a) Kreb's Cycle, (b) Glycolysis
• C. (a) Fermentation, (b) Glycolysis
• D. (a) Kreb's Cycle, (b) Fermentation

Answer 1

The correct option is A (a) Glycolysis, (b) Kreb's Cycle

Carbohydrates present in the food we consume is digested to form glucose. The glucose enters glycolysis and is oxidised to form pyruvic acid. Molecules of pyruvic acid formed in this process are converted into molecules of acetyl-co-enzyme-A which enters the Kreb's cycle. This is completely oxidised to form carbon dioxide and water with the release of energy.
