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 anaerobic, meaning it occurs without oxygen. In lactic - acid fermentation, cells convert pyruvic acid to lactic acid. During fermentation, NADH is converted back to NAD+ and no additional ATP is produced after glycolysis.

Answer:

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