    Hi, I'm just going over my notes about aerobic respiration and I'm a little confused to what reduction reactions are taking place.

    I understand that in all of these steps: glycolysis, the link reaction and the krebs cycle, H is given off and subsequently NAD becomes reduced NAD. But are H+ ions given off, or H atoms?

    Is this reaction correct? NAD+ + 2H+ + 2e- --> NADH + H+

    As in chemistry, reduction is the gain of H atoms, but it seems like reduction is the gain of H ions?

    You're forgetting that H ions accept electrons to form H atoms, so it's really reduction here.
