4

Cleavage into two triose phosphates

The six-carbon sugar splits into two three-carbon sugars: DHAP and glyceraldehyde 3-phosphate.

Glycolysis · reversible
5

Interconversion of triose phosphates

DHAP is converted into a second glyceraldehyde 3-phosphate, so both halves of glucose continue down the same path.

Glycolysis · reversible
6

Oxidation of glyceraldehyde 3-phosphate

G3P is oxidized. NAD+ picks up electrons to become NADH, and a phosphate is added to form a high-energy acyl-phosphate.

First two-carbon transfer

Transketolase transfers a two-carbon unit to make glyceraldehyde 3-phosphate and sedoheptulose 7-phosphate.

7

Three-carbon transfer

Transaldolase transfers a three-carbon unit to form erythrose 4-phosphate and fructose 6-phosphate.

8

Second two-carbon transfer

A second transketolase reaction yields another fructose 6-phosphate and glyceraldehyde 3-phosphate.
