Glycolysis is the first step in cellular respiration. Which option best summarizes the process?(1 point)
7 answers
Glycolysis is a metabolic pathway that occurs in the cytoplasm of cells. It involves the breakdown of one molecule of glucose into two molecules of pyruvate, along with the production of two molecules of ATP and two molecules of NADH. This process does not require oxygen and is a crucial step in both aerobic and anaerobic cellular respiration.
