Question

choose the correct answer. what process do cells rely on when oxygen is unavailable? chemosynthesis neutral respiration anaerobic respiration

Explanation:

When oxygen is unavailable, cells use anaerobic respiration to generate energy. Chemosynthesis is used by some bacteria to make food using chemical - energy sources, not a common energy - generating process in cells when oxygen is lacking. There is no such thing as "neutral respiration" in cell biology. Anaerobic respiration occurs in the absence of oxygen and allows cells to produce a small amount of ATP.

Answer:

anaerobic respiration
