Select the three statements below that accurately describe the difference between the oxidative phase and nonoxidative phase of the pentose phosphate pathway.
1) The oxidative phase produces NADPH and ribose-5-phosphate, while the nonoxidative phase produces only ribose-5-phosphate.
2) The oxidative phase involves the conversion of glucose-6-phosphate to ribulose-5-phosphate, while the nonoxidative phase involves the interconversion of various sugar phosphates.
3) The oxidative phase is irreversible, while the nonoxidative phase is reversible.
4) The oxidative phase occurs in the cytoplasm, while the nonoxidative phase occurs in the mitochondria.
5) The oxidative phase generates ATP, while the nonoxidative phase does not generate ATP.
