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 G
