alpha-ketoglutarate to succinyl CoA How many ATP's are produced through substrate-levelphosphorylation?

Question

Also need to know: alpha-ketoglutarate to succinyl CoA

1. How many ATP's are produced through substrate-level
phosphorylation?

2. How many ATP's can be produced through chemiosmotic
phosphorylation (with ETC)?

Explain your answer.

Answer 1

1. Substrate-level phosphorylation produces a net of 4 ATP. However, 2 ATP are used in the process for a total of 2 ATP.

2. ETC produces 34-36 ATP.

Here is the pathway for cellular respiration:

1 Glucose enters Glycolysis. The Glucose is broken down into (2) pyruvate acids. Pyruvate is converted to CoA which enters the Krebs Cycle. The Krebs Cycles produces 2 ATP & 6 CO2 (we exhale). Then Electron Transport Chain produces 34 ATP & H2O.
