Question

Already asked this but the last person was completely wrong, pretty simple question i just don't really get where the cycle begins

A.) Place the following glycolytic intermediates in the correct order:

(a) dihydroxyacetone phosphate

(b) glucose 6-phosphate

(c) 2-phosphoglycerate

(d) fructose 6-phosphate

(e) phosphoenolpyruvate

(f) fructose 1,6-bisphosphate

(g) 1,3-bisphosphoglycerate

(h) 3-phosphoglycerate

(i) glyceraldehyde 3-phosphate

(j) glucose

(k) pyruvate

B.) Place the following TCA cycle intermediates in the correct order:

(a) -ketoglutarate

(b) succinate

(c) oxaloacetate

(d) fumarate

(e) citric acid

(f) malate

(g) isocitric acid

(h) acety-CoA

(i) succinyl-CoA

Explanation / Answer

Glycolysis cycle starts with (j) glucose which converts to (b) glucose 6-phosphate which then converts to (d) fructose 6-phosphate this gives rise to (f) fructose 1,6-bisphosphate which gives two things one is (a) dihydroxyacetone phosphate and another is (i) glyceraldehyde 3-phosphate which turns to (g) 1,3-bisphosphoglycerate later converts to (h) 3-phosphoglycerate and then (c) 2-phosphoglycerate which produce (e) phosphoenolpyruvate gives (k) pyruvate

pyruvate goes to TCA cycle

Pyruvate gives acetyle co A which converts to (e) citric acid as cycle follow as below

(g) isocitric acid (a) -ketoglutarate (i) succinyl-CoA (b) succinate (d) fumarate (f) malate (c) oxaloacetate regeneration of (h) acety-CoA

(i) glyceraldehyde 3-phosphate

(j) glucose
