Question

which statements accurately describe fermentation? select two options. oxygen is present during this process. cells may convert pyruvic acid to lactic acid. nad+ is converted to nadh. fermentation is an anaerobic process. additional atp is produced after glycolysis.

Explanation:

Fermentation is an anaerobic process (no oxygen is present during fermentation). In lactic acid fermentation, cells convert pyruvic acid to lactic acid. During fermentation, NADH is converted to NAD+ (not the other way around as in option 3). After glycolysis, in fermentation, no additional ATP is produced (unlike aerobic respiration).

Answer:

B. Cells may convert pyruvic acid to lactic acid, D. Fermentation is an anaerobic process.
