Answer 1

Yes, glycolysis requires an input of energy. Pyruvate has less potential energy than glucose. Glycolysis produces a net gain of two ATP molecules. NAD+ acts as an electron acceptor in glycolysis.

Step-by-step explanation:

Yes, the process of glycolysis requires an input of energy. At the start of glycolysis, two molecules of ATP are used to split the glucose molecule into two pyruvate molecules. This energy is needed to break the bonds in glucose and prepare it for further processing. As glycolysis proceeds, energy is released and used to produce ATP. The net gain of ATP molecules during glycolysis is two.

Pyruvate has less potential energy than glucose. During glycolysis, some energy is released as glucose is metabolized and converted into pyruvate. Therefore, the potential energy of pyruvate is lower than that of glucose.

Glycolysis produces a net gain of two ATP molecules.

The molecule that acts as an electron acceptor in glycolysis is NAD+ (nicotinamide adenine dinucleotide). It accepts high-energy electrons from glucose and is reduced to form NADH, which is later used in stage III of cellular respiration to produce more ATP.
