Question

glycolysis is a step in the breakdown of glucose. which statements describe glycolysis? it is common to aerobic and anaerobic respiration. it breaks down glucose to two pyruvate molecules. it occurs only when an animal is breathing. it occurs in a cells mitochondria.

Explanation:

Glycolysis is the first - stage of cellular respiration. It is common to both aerobic and anaerobic respiration as it occurs without the need for oxygen initially. In glycolysis, one molecule of glucose is broken down into two molecules of pyruvate. It occurs in the cytoplasm, not the mitochondria, and is not dependent on an animal breathing (as it is part of anaerobic respiration too).

Answer:

It is common to aerobic and anaerobic respiration.
It breaks down glucose to two pyruvate molecules.
