Kreb's Cycle - the release of 2 ATP molecules/molecule of glucose.

*GTP :P

Also remember 3 NADH and 1 FADH produced per cycle - i.e. per acetyl-CoA - i.e. 6 NADH and 2 FADH per glucose.

Huh?

(this is VCE bio right?)

ATP is more than enough detail for the Krebs cycle lol

I've always thought that GTP is produced which then in turn transfers the phosphate to an ADP, so you do end up with ATP, but ATP isn't directly produced in from the citric acid cycle.

Whoops.

Edit - yeah, it's GTP that's produced, but guess in VCE they don't look at that =.=

Yeah, you're right, but GTP definitely isn't mentioned in VCE, so ATP's fine

I think ATP mentionings are sufficient, and knowing the energy yield for every process:

*Glycolysis - the net output of 2 ATP molecules/ glucose molecule.
*Kreb's Cycle - the net output of 2 ATP molecules/glucose molecule.
*Electron Transport Chain - the net output of 32-34 ATP molecules/glucose molecule.

:) Those other aspects (i.e. NADH, ADP and ATP, FADH etc) can be elaborated upon when you delve deep into each process and look at chemical changes, inputs/outputs, etc. :)

Don't worry about mentioning 'net' for the Kreb's cycle and the electron transport chain. It's just glycolysis you have to worry about

^Both of those questions are /way/ too much detail for VCE bio. Aerobic respiration is like 1/6th of a single AoS, they don't expect and/or examine that depth.

Take #3 haha :p

Glycolysis: the net output of 2 ATP molecules/glucose molecule.
Kreb's Cycle: the release of 2 ATP molecules/glucose molecule
Electron transport chain: the release of 32-34 ATP molecules/glucose molecule.

Yes.

YAY!! :) haha, finally got that expression correct!
