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.

(1) A net gain of 38 ATPs

(2) Production of 38 ATPs

(3) Production of 32 ATPs

(4) Production of 36 ATPs

(1) Only partial breakdown of glucose

(2) Net gain of only two molecules of ATP for each molecule of Glucose

(3) NADH is oxidized to NAD+ rather slowly in fermentation

(4) All of these

(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) Within Krebs’ cycle

(2) As Pyruvate or Acetyl CoA

(3) As PGAL

(4) Both A and B

(1) Acetyl CoA

(2) PGAL

(3) BPGA

(4) Pyruvic Acid

(1) Some Ratio

(2) Some amount of oxygen

(3) Some amount of carbon dioxide

(4) Cannot be one

(1) The type of respiratory substrate used

(2) The place in which respiration is occurring

(3) The amount of ventilation

(4) Breathing surface

1. 3,3

2. 6,3

3. 3,6

4. 6,6

(1) A fatty acid

(2) C51 H98 O6

(3) C48 H96 O5

(4) Both A and C
