Answer:
Cell respiration begins with Glycolysis
.
Explanation:
Glycolysis is the first and initial step in the cellular respiration. Cellular respiration is the anaerobic process, which takes place in cytosol of the cells. Two molecule of pyruvate(CH3COCOO-) are formed from 1 molecule of glucose(C6H12O6)through glycolysis. The NADH and ATP are high energy molecules formed when the free energy are released. It is the process which takes place through a series of ten enzyme catalysed reactions. 10 enzymes are required to break down the sugar molecule. It occurs in cytoplasm.
