MUSCLE PHYSIOLOGY

Detailed explanation-1: -Glycolysis is a partial breakdown of a six-carbon glucose molecule into two, three-carbon molecules of pyruvate, 2NADH +2H+, and 2 net ATP as a result of substrate-level phosphorylation. Glycolysis occurs in the cytoplasm of the cell.

Detailed explanation-2: -ATP formation At the end of glycolysis, the following reactions have occurred: Glucose (6C) has been broken down into two molecules of pyruvate (3C) Two hydrogen carriers have been reduced via oxidation (2 × NADH + H +) A net total of two ATP molecules have been produced (4 molecules were generated, but 2 were used)

Detailed explanation-3: -An enzyme, RuBisCO, catalyzes the fixation reaction, by combining CO2 with RuBP. The resulting six-carbon compound is broken down into two three-carbon compounds, and the energy in ATP and NADPH is used to convert these molecules into G3P.
