An organism is able to grow on fructose or glucose and the route of carbon flow from glucose or fructose to pyruvate for this isolate is as shown.
Note: 1 fructose1,6P2 splits into 1 3PG+1 pyruvate)

A) Provide the net reaction for 1 fructise yielding 2 pyruvates; account for AMP/ADP and NAD+/NADH.

B) Does this organism gain energy through substrate level phosphorylation in glycolysis from glucose? What about from fructose?

Glucose NADH+H NAD Fructose ADP AMP NAD NADH H 2-P. AMP ADP e the net reaction for l fructose yielding

Solution

A) Net reaction for fructose to pyruvate is 1 ATP and 1 NADH. becauese in this question you mentioned fructose 1 ,6 phosphate split in to 1-3 pospho glycerate and directly one pyruvate. this pyruvate does not enter into pathway, only one 1-3 pospho glycerate enter into the remaining glycolysis path way, and it generates 1 ATP and 1 NADH.

B) Substrate level pphophorylation occurs from the fructose carbon source. but net energy gain is different. Glucose gives less net energy than Fructose, Glucose gives only one NADH, gained ATP\'s are utilized by Previous steps in the glycolysis.
