Which of the following complex does not allow transfer of Protons across the mitochondrial membrane but transfer of electrones in the inner membrane?

(1) Complex II

(2) Complex III

(3) Complex IV

(4) Complex I

(1) Complex I

(2) Complex II

(3) Complex III

(4) Complex V

(1) Because it is limited to the terminal stage of the process

(2) Because it drives the whole process by removing hydrogens from the system

(3) It acts as the final hydrogen acceptor not the Electron acceptor

(4) Both B and C

(1) Because of the presence of oxygen

(2) Because here proton gradient is maintained by the energy of oxidation and reduction

(3) Because of the presence of ADP and oxygen

(4) Because of the presence of Phosphorylation derived by oxygen

(1) 2 ATPs, 3 ATPs

(2) 5 ATPs, 3 ATPs

(3) 3 ATPs, 3 ATPs

(4) 3 ATPs, 2 ATPs

(1) Chemical

(2) Electrical

(3) Osmotic

(4) Electrochemical

(1) Glucose is the favoured substrate for respiration

(2) All carbohydrates are usually first converted into glucose before they are used for respiration

(3) Other respiratory substrates are also respired but they do not enter the respiratory pathway at very first step

(4) Fats directly enter the respiratory pathway

(1) Fatty acids enter at the step of formation of BPGA

(2) Fatty acids enter as acetyl CoA

(3) Fatty acids enter as PGAL

(4) Fatty acids enter as Pyruvate

(1) Within Krebs’ cycle

(2) As Pyruvate or Acetyl CoA

(3) As PGAL

(4) Both A and B

(1) Some Ratio

(2) Some amount of oxygen

(3) Some amount of carbon dioxide

(4) Cannot be one
