Question

Looking for detailed explanations for Biochem questions:

26. Which of the following statements about the chemiosmotic theory is correct? A. The free energy released in the redox reactions of the ETC is stored in an electrochemical gradient of protons across the inner membrane. B. The potential energy stored in the form of a proton gradient is subsequently harnessed through the conformational changes in ATP synthase C. Oxidative phosphorylation can occur in the absence of an intact inner mitochondrial membrane. D. Answers A and B E. Answers A, B and C 27. Which of the following statements is FALSE regarding the biochemistry associated with Complex IV? A. Each Cytochrome c molecule functions as a two-electron donor. B. To generate two water molecules, complex IV requires a total of 4 electrons and 4 H from the matrix. C. Electrons move through a series of electron carrying cofactors within complex IV from low standard reduction potential to high standard reduction potential D. Answer choices A and C are both False E. Answer choices A, B and C are all False

Explanation / Answer

(26) D. A and B are correct

chemiosmotic hypothesis suggests that the action of ATP synthase is coupled with that of a proton gradient, the proton motive

(27)A. each of the cytochrome c acts as a two-electron carrier

Cytochrome c is a single electron carrier

(28) D.All of the above

A single strand RNA genome will have all the nucleotides which can be in different proportions but all together should make up 100%

(29)E.both B and C are false statements
