Atp Through Substrate Level Phosphorylation 536592

Aliens land. You find out that in almost all ways, their metabolism is similar to that of humans. One significant difference is that they don’t use NAD/NADH. At each and every step in the oxidation of biological molecules where humans use NAD/NADH aliens use FAD/FADH-2. At steps where humans use FAD/FADH-2 the aliens do as well.

a) Who makes more ATP or mole of glucose, aliens or humans? Describe.

b) Who makes more ATP through substrate level phosphorylation?
