Fructose catabolism gives the same products as glucose breakdown namely 2x pyruvate, 2x ATP and 2x NADH.TrueFalse

Break Down the Problem

1. Identify the Comparison: Determine whether fructose catabolism produces the same end products as glucose catabolism.
2. Understand the Pathways: Review the metabolic pathways for both fructose and glucose breakdown.

Relevant Concepts

3. Glycolysis: Both fructose and glucose are broken down through glycolysis, but they enter the glycolytic pathway at different points.
4. Products of Glycolysis: The standard yield from one glucose molecule through glycolysis is:
   • 2 Pyruvate
   • 2 ATP (net gain)
   • 2 NADH

Analysis and Detail

5. Fructose Breakdown:
   • When fructose is metabolized, it is first converted to dihydroxyacetone phosphate (DHAP) and glyceraldehyde.
   • Eventually, it also yields 2 Pyruvate, 2 ATP (net gain), and 2 NADH, similar to glucose.

Verify and Summarize

6. Conclusion: After examining both pathways, it can be confirmed that the products of fructose catabolism align with those of glucose breakdown.

Final Answer

True: Fructose catabolism gives the same products as glucose breakdown, yielding 2 Pyruvate, 2 ATP, and 2 NADH.
