What is the role of the sixth enzyme in glycolysis?

<p>The sixth enzyme adds a second phosphate to glyceraldehyde 3-phosphate, creating 1, 3 bisphosphoglycerate, while two electrons are transferred to NAD plus, which is reduced to NADH.</p> Signup and view all the answers

Study Notes

Energy Production in Cells

  • The primary energy source for living cells is ATP (Adenosine Triphosphate).

Glycolysis Pathway

  • The sequence of enzyme reactions that breaks down glucose into pyruvate molecules is called glycolysis.
  • Mitochondria are the primary source of ATP in cells.

Initial Steps of Glycolysis

  • The first step in the glycolysis pathway involves the conversion of glucose into glucose-6-phosphate.

Conversion of Dihydroxyacetone Phosphate

  • Dihydroxyacetone phosphate must be converted into glyceraldehyde-3-phosphate before it can continue with glycolysis.

Role of Sixth Enzyme

  • The sixth enzyme in glycolysis catalyzes the conversion of fructose-6-phosphate into fructose-1,6-bisphosphate.

ATP Consumption in Glycolysis

  • Halfway through glycolysis, the cell has consumed 2 ATP molecules.

Product of Seventh Enzyme

  • The product of the seventh enzyme in glycolysis is glyceraldehyde-3-phosphate.

Role of Ninth Enzyme

  • The ninth enzyme in glycolysis catalyzes the conversion of 1,3-bisphosphoglycerate into 3-phosphoglycerate.

Final Products of Glycolysis

  • The final products of glycolysis are 2 molecules of pyruvate, 2 ATP molecules, and 2 NADH molecules.
