Question
Process that occurs in the cytoplasm in the absence of oxygen;
Glucose is converted to pyruvic acid; ATP and NADH are also
produced
2.
If oxygen is not present, pyruvate and NADH enter this metabolic
pathway; occurs in your muscles; used by bacteria
3.
If oxygen is not present, pyruvate and NADH enter this metabolic
pathway; produces carbon dioxide and ethanol; used by yeast
and some plant cells
4.
If oxygen is present, pyruvate is further broken down; NADH
produced is used to make large amounts of ATP
