Which statement about glycolysis is true?
A
Glycolysis is the final step in cellular respiration.
B
Glycolysis produces a net gain of two ATP molecules per glucose molecule.
C
Glycolysis occurs in the mitochondria of the cell.
D
Glycolysis requires oxygen to proceed.
Verified step by step guidance1
Understand that glycolysis is a metabolic pathway that breaks down glucose into pyruvate, producing ATP and NADH in the process.
Recognize that glycolysis is the first step in cellular respiration, not the final step. It occurs before the Krebs cycle and oxidative phosphorylation.
Identify the location of glycolysis: it takes place in the cytoplasm of the cell, not in the mitochondria.
Note that glycolysis is an anaerobic process, meaning it does not require oxygen to proceed.
Calculate the net gain of ATP in glycolysis: for each glucose molecule, glycolysis produces a net gain of two ATP molecules, as it generates four ATP molecules but uses two ATP molecules in the initial steps.
