Q. No.The process used in conversion of Pyruvate to Acetyl CoA is
1. Oxidative dehydration
2. Oxidative decarboxylation
3. Oxidative phosphorylation
4. Reductive phosphorylation.
If RQ is 0.6 in a respiratory metabolism, it would mean that
1. Carbohydrates are used as respiratory material
2. Organic acids are used as respiratory substrate
3. The oxidation of the respiratory substrate consumed more oxygen than the amount of CO released
4. The oxidation of respiratory substrate consumed less oxygen than the amount of CO2 released
In ETS, complex V is
1. ATP synthase
2. NADH dehydrogenase
3. Cytochrome c oxidase
4. Cytochrome bc complex
The first step of decarboxylation in cellular respiration is
(1) Conversion of PGAL to DHAP
(2) Conversion of PGAL to PGA
(3) Conversion of Pyruvate to Acetyl CoA
(4) Conversion of BPGA to PGA

(1) 2NADH
(2) 4NADH
(3) 3NADH
(4) 12 NADH
The substrate which enters in Krebs’ cycle during oxidation of Glucose is
(1) Pyruvate
(2) Acetyl CoA
(3) Oxaloacetate
(4) Succinate
Who elucidated Krebs’ cycle for the very first time?
(1) Frederick Kreb
(2) Hans Kreb
(3) Edward Kreb
(4) Tilman Kreb
The order of electron transport is
(1) Complex l- Complex III- Complex IV- Complex V
(2) Complex lI- Complex III- Complex IV- Complex V
(3) Complex l- Complex III- Complex IV
(4) Complex l- Complex II- Complex IV- Complex V
Which of the following complex has got one Domain present in matrix and other domain in the inner membrane?
(1) Complex I
(2) Complex II
(3) Complex III
(4) Complex V
Which of the following is not the assumption considered to finalize the balance sheet of respiration?
(1) There is sequential, orderly pathway functioning with one substrate forming the next and with glycolysis following TCA and Then ETS pathway
(2) The NADH synthesized in Glucolysis is transferred into the mitochondria and undergoes Oxidative Phosphorylation
(3) No anabolism from respiratory intermediates.
(4) Glucose, Proteins and Fats are being respired altogether.
