Her muscles are using ATP faster than it can be produced by aerobic cellular respiration. How does the runner continue the race? Select the best answer. Her muscle cells use lactic acid fermentation so that glycolysis can continue producing ATP by substrate-level phosphorylation. Her muscles fatigue and she has to stop. She should have carbohydrate-loaded the night before She should breath into a paper bag.arrow_forwardIn which of the following processes is glucose 6-phosphate the end product?

- What is meant by glycolysis having an investment and payoff phase? It initially requires ATP but returns more later. It transfers molecules from the cytosol to the mitochondrion. Glucose is split in half, then rejoined later Oxygen is required initially but released again later.arrow_forwardWhich of the following correctly describes ATP usage in gluconeogenesis and glycolysis? O ATP is consumed by gluconeogenesis and produced by glycolysis. O ATP is consumed by both gluconeogenesis and glycolysis. O ATP is produced by gluconeogenesis and consumed by glycolysis. O ATP is produced by both gluconeogenesis and glycolysis. • Previous Nextarrow_forwardWhich metabolic pathway converts glucose into two molecules of pyruvate and ATP? Group of answer choices Gluconeogenesis Glycogenesis Glycogenolysis Glycolysisarrow_forward
- Which statement is NOT correct about glycolysis? O Glycolysis occurs in both aerobic and anaerobic respiration. O During glycolysis, electron carriers are produced O Glycolysis uses two ATP but forms four ATP, resulting in a net gain of two ATP molecules. Glycolysis involves splitting the glucose into 2 pyruvate moleculesarrow_forwardWhich of the following statements is true regarding the process of glycolysis? It both requires the input of ATP and produces ATP. It produces ATP by oxidative phosphorylation. It is an alternative to fermentation. It involves changing 1 molecule of glucose into 1 molecule of pyruvate. It occurs in the cell membranes of bacteria.arrow_forwardWhy does it take two reactions of gluconeogenesis to reverse the final step of glycolysis? Reverse reaction is not possible directly without proper enzyme.Reverse reaction is not possible directly due to low concentration of product.Reverse reaction is not energetically possible directly.Reverse reaction is not possible directly at body temperature.arrow_forward
- In glycolysis, _______ ATP are formed, and if sufficient oxygen is present, _______ ATP are formed.arrow_forwardWhich of the following statements about glycolysis is FALSE? O It generates 2 molecules of ATP net per molecule of glucose. O It is located in the cytosol of both prokaryotes and eukaryotes. O It requires an input of 2 molecules of ATP per molecule of glucose to generate fructose-1,6-bisphosphate. O It generates 2 molecules of NADH per molecule of glucose. O It liberates 2 molecules of CO2 per molecule of glucose.arrow_forwardSometimes, ATP is referred to as the “energy-storage molecule.” The cell does not actually store energy as a lot of extra ATP but as glycogen or triacylglycerides. Why do you suppose this is the case?arrow_forward
