Be sure to show the structure of all of the intermediates along the pathway and show the name of each enzyme over the arrow. Also be sure to indicate other co-substrates or cofactors required (ie. ATP, NAD+, FAD, etc…)arrow_forward

Write the reac- tions for each step using words. They need not be balanced with respect to charge, protons released or consumed, and stoichiometry. Consider 2.5 ATP/NADH oxidized and 1.5 ATP/FADH2 oxidized. Enzymes need not be named.
