Which of the following statements about glycolysis is false?

A) glycolysis has steps involving oxidation-reduction reactions


B) the enzymes of glycolysis are located in the cytosol of the cell


C) glycolysis can operate in the complete absence of O2


D) the end products of glycolysis are CO2 and H2O


E) glycolysis makes ATP exclusively through substrate level phosphorylationWhich of the following statements about glycolysis is false?
D: The end process of cellular respiration are CO2 and H20 The end products of glycolysis are acids (lactic or pyruvic depending on the organism)Which of the following statements about glycolysis is false?

either B or E





sorry im no help
D:The end products of glycolysis are 2 reduced NAD(nicotineamide adenine dinucleotide),2 ATP molecules %26amp; 2 Pyruvate molecules.
D:because the end of glycolysis is 2NADH+2ATP+2pyruvic acid that convert into acetylCO-A or into lactic acid depends on the type of respiration
D seems like it could be false because CO2 and H2O are not the only end products of glycolysis...as was mentioned before, pyruvic acid is the main end product of interest, as it goes on to fuel the Krebs cycle. However, statement E is ';more false'; because there is a step in glycolysis in which an ATP is generated by oxidative phosphorylation. NAD and NADH undergo a redox reaction, releasing energy to generate ATP via oxidative phosphorylation. Substrate level phosphorylation does occur in glycosis, but not *exclusively* like the statement says.





All the other statements are most definitely true.
