WebWhy is glycolysis described as having an investment phase and a payoff phase? a. It shifts molecules from cytosol to mitochondrion. b. It uses stored ATP and then forms a net increase in ATP. c. It both splits molecules and assembles molecules. d. It uses glucose and generates pyruvate. e. It attaches and detaches phosphate groups. b WebDec 18, 2016 · The process of glycolysis (which literally means “glucose breaking”) begins all forms of cellular respiration After this energy investment phase, the “payoff” or energy harvesting phase takes place. During this phase, G3P is converted into pyruvate in a process that produces 4 ATP.
WebThe first and third steps of glycolysis are both energetically unfavorable. This means they will require an input of energy in order to continue forward. Per glucose molecule, 1 ATP is required for each of these steps. Therefore, a total of 2 ATP is needed during the energy investment phase of glycolysis.
