What is the energy cost of producing glucose through gluconeogenesis?
What is the energy cost of producing glucose through gluconeogenesis?
- $2 pyruvate + 4 ATP + 2 GTP + 2 NADH \rightarrow glucose + 4 ADP + 2 GDP + 2 NAD+ + 6 Pi$ (correct)
- $2 pyruvate + 2 ATP + 2 GTP + 2 NADH \rightarrow glucose + 2 ADP + 2 GDP + 2 NAD+ + 6 Pi$
- $2 glucose + 4 ATP + 2 GTP + 2 NADH \rightarrow pyruvate + 4 ADP + 2 GDP + 2 NAD+ + 6 Pi$
- $glucose + 2 ATP + 2 GTP + 2 NADH \rightarrow 2 pyruvate + 4 ADP + 2 GDP + 2 NAD+ + 6 Pi$
