26
in step 8...
NAD+ is reduced to NADH
27
the citric acid cycle produces...
3NADH, 2CO2, FADH2, GTP
28
Control points of the citric acid cycle
citrate synthase, isocitrate dehydrogenase, a-ketoglutarate dehydrogenase

32
knows dat
a-ketoglutarate dehydrogenase
33
inhibition occurs at steps...
pyruvate, 1, 3,4
34
inhibition at pyruvate
inhibited by ATP, acetyl-CoA, and NADH
35
inhibition at step 1
inhibited by ATP, NADH, succinyl-CoA, and citrate
36
inhibition at step 3
inhibited by ATP, NADH
37
inhibition at step 4
inhibited by ATP, NADH, and succinyl-CoA
38
steps requiring electron acceptors (PIKSM)
pyruvate, isocitrate, a-ketoglutarate, succinate, malate | Please I know shes mean
