When explaining the function of glycolysis as it relates to anaerobic metabolism, the faculty will mention which of the following key points? Select all that apply
A) Glycolysis requires the use of oxygen to begin the process.
B) Glycolysis occurs in mitochondrion-lacking cells.
C) Glycolysis provides the majority of the body's energy needs.
D) Pyruvic acid is an end result from a series of reactions that converts glucose.
Ans: B, D
Feedback:
Glycolysis is the anaerobic process by which energy is liberated from glucose, and it is an important source of energy for cells that lack mitochondria. The process also provides a temporary source of energy for cells that are deprived of an adequate supply of oxygen. Glycolysis involves a sequence of reactions that converts glucose to pyruvic acid, with the concomitant production of ATP from ADP. It accounts for a small minority of the body's energy needs and results in NADH, hydrogen ions, ATP, and pyruvic acid.
