The reaction where electrons are removed from carbon initially present in glucose is the formation of Glyceraldehyde-3-phosphate and Dihydroxyacetone phosphate.
Glycolysis is the process of the formation of glucose into 2 molecules of pyruvate. It is a cellular process, the molecule reduces in carbon number to form pyruvate thus electrons are removed in the fourth step of glycolysis. The reaction is:
Fructose-6-phosphate(6 carbon) →→→ Glyceraldehyde-3- phosphate(3 carbon) + Dihydroxyacetone phosphate (3 carbon)
This reaction occurs in the presence of the enzyme Fructose bisphosphate aldolase. The reaction generates a reduced electron carrier NAD⁺
Dihydroxyacetone phosphate further reverses into glyceraldehyde-3-phosphate, thus leading to the formation of 2 molecules of pyruvate(a 3-carbon molecule).
