Which of the following is true regarding glycolysis?
(I)There is a net oxidation of substrate carbon atoms.
(II)There is no net release of free energy.
(III)Pyruvate is generated only during aerobic glycolysis.
(IV)There is 2 ATP formed for every 2 glucose molecules.

Only statement I is true. Glycolysis involves the conversion of glucose to pyruvate with the net production of 2 ATP and 2 NADH molecules. During the process, carbon atoms from glucose are oxidized and there is a net gain of free energy. Pyruvate is generated in both aerobic and anaerobic glycolysis. Statement II is false because there is indeed a net release of free energy during glycolysis. Statement IV is also false because 2 ATP molecules are formed from one glucose molecule, not two.
