How many ATPs are in glycolysis, the krebs cycle and etc?

i thought its:
2 for glycolysis
2 for krebs
and and 32 for etc, is this right?

also, when you count the amount of ATPs in each cycle, do you include the amount of ATPs for each NADH and each FADH?

Glycolysis
Net 2 ATP
2 NADH

Pyruvate to Acetyl CoA
2 NADH

Kreb's Cycle
2 ATP
6 NADH
2 FADH2

* Note that after the completion of glycolysis there are two pyruvates formed, so the Pyruvate to Acetyl CoA and Kreb's Cycle are occuring once for each pyruvate (two times). Another important point to note is that glycolysis occurs in the cytostol while the electron transport chains is located in the inner mitochondrial membrane so transporting the 2 NADH from glycolysis into the mitochondria costs 2 ATP.

In the electron transport chain, each NADH is worth 3 ATP and each FADH2 is worth 2 ATP.

The net ATP gain per glucose molecule is 36

Hope I got everything correct.

PS: the ATP you get from krebs is by way of GTP.it doesnt directly produce ATP--just thought i'd throw that in.

thanks so much for your help guys!
