(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

(1) Volume of Carbon-dioxide evolved

(2) Ratio of volume of oxygen consumed to volume of Carbon-dioxide evolved

(3) Ratio of volume of Carbon-dioxide evolved to the volume of oxygen consumed

(4) Ratio of volume of oxygen evolved to volume of Carbon-dioxide consumed

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
