Cellular Respiration Chapter 6.6

Question 1

Explain how to arrive at the estimate that each glucose molecule theoretically yields 36 Atps

Answer 1

1.Glycolysis (substrate level phophorylation) (2)
2.Krebs Cycle (2)
3.3 per each NADH/ ETC = 3x10= (30)
4.2 per each FADH/ ETC = 2X2 = (4)
= 38 ATPs
-2 for energy used up in transporting NADH in to the matrix =36

Question 2

How much NADH is produced in each cycle

Answer 2

Glycolysis =2
Pyruvate to CoA =2
Krebs Cycle =6
Total =10 NADHS

Question 3

How many FADH

Answer 3

2 from the Kreb cycle
