Q. No.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
(1) Within Krebs’ cycle
(2) As Pyruvate or Acetyl CoA
(3) As PGAL
(4) Both A and B
Respiratory Quotient
(1) Some Ratio
(2) Some amount of oxygen
(3) Some amount of carbon dioxide
(4) Cannot be one
Respiratory Quotient is
(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
The value of respiratory Quotient actually depends upon
1. The type of respiratory substrate used
2. The place in which respiration is occurring
3. The amount of ventilation
4. Breathing surface
For the substrate Glucose, how many Oxygen are used and how many Carbon-dioxide are evolved?
(1) 3,3
(2) 6,3
(3) 3,6
(4) 6,6
Tripalmitin
Which of the following is wrong?
(1) A fatty acid
(2) C51 H98 O6
(3) C48 H96 O5
(4) Both A and C
How many Carbon-dioxide are evolved in respiration of two molecules of Tripalmitin?
(1) 102
(2) 145
(3) 98
(4) 6
The RQ of a substrate is found to be 0.9 what would be that substrate?
(1) Carbohydrate
(2) Fatty Acid
(3) Lipid
(4) Protein
