Glycolysis is the name given to a metabolic pathway occurring in many different cell types. It consists of 11 enzymatic steps that convert glucose to lactic acid. Glycolysis is an example of:

A) aerobic metabolism.
B) anabolic metabolism.
C) a net reductive process.
D) fermentation.
E) oxidative phosphorylation

The correct answer is - option D. fermentation.

Explanation:

Glycolysis is the metabolic pathway in which metabolize the sugar and produce pyruvate molecule or lactic acid and produce the energy in the form of ATP and NADH.

Glycolysis is an example of the fermentation as fermentation is also a metabolic pathway in which an organism turns glucose into the lactic acid or the alcohol to produce energy for electron transfer system.

Thus, the correct answer is - option D. fermentation.

"d.) carbon dioxide and hydrogen sulfide"

c is the answer to this question. altitude affects the weather because air molecules evaporate.
