a. cell respiration
b. glycongenolysis
c. glycolysis
d. electron transport chain
e. kreb’s cycle

A. Cell respiration

Explanation:

Cell respiration is the process wherein glucose (C6H12O6) is completely oxidized into water and carbon dioxide. The process occurs in three steps namely, glycolysis, Kreb's cycle, and oxidative phosphorylation.  

Glycolysis breaks down the glucose into pyruvate. The pyruvate enters link reaction and is converted into acetyl CoA. The acetyl CoA enters the Kreb's cycle and is completely oxidized into CO2 and H2O. The energy released during these reactions is stored in the form of ATP, NADP, and FADH2.
