In the given diagrammatic representation of ATP synthesis in mitochondria, A, B and C are respectively:
1. 2 , and
2. 2 , and
3. 4 , and
4. 4 , and
During the process of respiration redox equivalents are removed:
1. In form of hydrogen atom.
2. In form of an electron.
3. In form of H2O.
4. In form of ATP.
Complete the given reaction of the cycle present in the mitochondrial matrix:
1. A—Succinic acid; B—Pyruvate dehydrogenase.
2. A—Malic acid; B—Transacetylase.
3. A—OAA; B—Citrate synthase.
4. A— -KGA; B Thiokinase.
The individual amino acid enter the respiratory pathway at
(1) Within Krebs’ cycle
(2) As Pyruvate or Acetyl CoA
(3) As PGAL
(4) Both A and B
Oxidation of two molecules of NADH gives
(1) 6 ATPs
(2) 3 ATPs
(3) 1 ATP
(4) 2 ATPs
Cytochrome c includes except
(1) Mobile carrier
(2) Present on outer surface of inner membrane
(3) Acts as mobile carrier for transfer of electrones between complex III and IV
(4) Transfers electrones from complex II to complex III as well
Complex three is
(1) NADH dehydrogenase
(2) Succinate dehydrogenase
(3) Cytochrome C oxidase
(4) Cytochrome bc1 complex
The reduced ubiquinone is
(1) Ubiquinol
