How many ATP molecules are generated from one complete metabolism of one molecule of maltose assuming all electrons of cytosolic NADH are transferred through the dihydroxyacetone phosphate/glycerol 3-phosphate shuttle?
What steps in glycolysis generate substrate-level phosphorylation, and how many ATP molecules are generated in this way in this pathway? How does the generation of ATP by substrate-level phosphorylation differ from ATP generation by oxidative phosphorylation?

- Only the one question displayed is neededarrow_forwardThe overall reactions for gluconeogenesis and glycolysis are given below. What is the energy cost (in ATP equivalents) of transforming one molecule of glucose to pyruvate (via glycolysis) and back to glucose (via gluconeogenesis)? Gluconeogenesis: 2 pyruvate + 4 ATP + 2 GTP + 2NADH + 4H₂O Glycolysis: Glucose + 2ADP + 2P₁ + 2NAD+ - 2 pyruvate + 2ATP + 2NADH + 2H+ + 2H₂000 Select one: O a. 2 ATP O b. 4 ATP O c. 6 ATP O d. 8 ATP Prev Page glucose + 4ADP + 2GDP + 2P₁ + 2NAD+ + 2H+ MI 21 22 00:508D DAD 1=1 SE 30: DONDOK 23 24 25 26 27 28 29 30 Report question issue B Next Page Garrow_forwardAlthough both hexokinase and phosphofructokinase catalyze irreversible steps in glycolysis and the hexokinase-catalyzed step is first, phosphofructokinase is nonetheless the pacemaker of glycolysis. What does this information tell you about the fate of the glucose 6-phosphate formed by hexokinase? Glucose 6-phosphate must be unstable and release its phosphoryl group over time. Glucose 6-phosphate must be utilized by other metabolic pathways. Glucose 6-phosphate must allosterically inhibit phosphofructokinase, but not hexokinase. Glucose 6-phosphate must be wasted when it is produced in excess.arrow_forward
