Q

What are some characteristics of respiration? Fermentation? Both?

A

Respiration
High ATP yield; most from oxidative phosphorylation
Most carbon released as CO2
Electrons reduce an external electron acceptor (e.g., O2).

Fermentation
Low ATP yield; primarily from glycolysis
Electrons from catabolism end up back on partially oxidized substrate.
Most carbon remains in organic form.

Both
Important for catabolism of sugars
NADH major electron carrier
Pyruvate is major intermediate.

Q

Reduction will have a free electron on the reactant side
