10

What process uses organic molecules to remove the electrons carried by NADH?

Fermentation

11

What compounds are produced by fermentation?

Alcohols, Organic acids, CO2

12

What process catabolizes pyruvate?

TCA cycle

13

What process produces mass amounts of NADH and FADH2?

TCA cycle

14

What process involves electrons in NADH being passed to an electron transport system and on to an inorganic acceptor?

TCA cycle

15

What process recycles electrons from NADH and FADH2?

Respiration

16

What acts as a terminal electron acceptor in aerobic respiration?

O2

17

What acts as a terminal electron acceptor in anaerobic respiration?

Inorganic molecules
