WebIn many cases, pathways are regulated through enzymes that catalyze individual steps of the pathway. If the enzyme for a particular step is active, that step can take place quickly, but if the enzyme is inactive, the step will happen slowly or not at all. WebThe steps of the Krebs cycle are as follows: Formation of a 6-carbon molecule: Acetyl CoA, a 2-carbon molecule, combines with oxaloacetate, a 4-carbon molecule. This forms citrate, a 6-carbon molecule. Coenzyme A is also lost and exits the reaction as a by-product when citrate is formed. Formation of a 5-carbon molecule: Citrate is converted ...
