Question

I need help solving these questions. I think that is the answer but I would like to know how to solve it and why the others cannot be the answer. Thank you!

31. One complete rotation of the mitochondrial ATP synthase requires about protons: e. 6 c. 12 a. 3 b. 6 32. One NADHoxidation by the electron transport system results in the translocation of protons e. 32 d. 30 c. 10 a. 4 33. The addition of an uncoupler such as 2,4-dinitrophenol can oxygen consumption and symthesis of ATP/ a. ncrease decrease. b. decrease Vincrease. c. decrease decrease d. increase increase

Explanation / Answer

31.d.9

A complete rotation of ATP synthase requires 3.33x3= ~9.9 protons

Each 360-degree rotation of the subunit leads to the synthesis and release of three molecules of ATP. Each ATP generated requires the transport of 10/3 = 3.33 protons

32. c.10

A total of 10 protons are translocated from the mitochondrial matrix per 2 electrons transferred from NADH to oxygen via the respiratory chain.

33. a.increase/decrease

2,4-DNP causes uncoupling of protons resulting in increased oxygen consumption and decreased ATP synthesis.
