Why is glycolysis described as having an energy investment phase and an energy payoff phase? Why is glycolysis described as having an energy investment phase and an energy payoff phase? Early steps consume energy from ATP and NADH, and later steps store an equal amount of energy in ATP and NAD+. Early steps consume energy from ATP, and later steps store an increased amount of energy in ATP and NADH. Early steps consume energy from ATP and NADH, and later steps store an increased amount of energy in ATP and NADH. Early steps consume energy from ATP and NADH and later steps store an increased amount of energy in ATP. Early steps consume energy from NADH, and later steps store an increased amount of energy in ATP and NADH.

The answer is; Early steps consume energy from ATP, and later steps store an increased amount of energy in ATP and NADH

In the initial stage (energy consuming), 2 ATPs and consumed to convert glucose to the high energy fructose-1,6 biphosphate. The fructose-1,6 biphosphate is later split into 2 glyceraldehyde-3-phosphate (G3P). In the energy-releasing phase, each G3P is used to generate 2 ATPs and an NADH are released. Therefore, there is a net positive energy of 2 ATPs and 2 NADHs.
