Which of the following statements is incorrect?
(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
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
For the synthesis of Fatty acids, which of the following substrates will be used?
(1) Acetyl CoA
(2) PGAL
(3) BPGA
(4) Pyruvic Acid
Respiratory Quotient
(1) Some Ratio
(2) Some amount of oxygen
(3) Some amount of carbon dioxide
(4) Cannot be one
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

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
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
Which of the following is not correct?
(1) In living organisms, respiratory substrates are often more than one
(2) Pure proteins and fats can also be used as respiratory substrate
(3) Fermentation takes place under anaerobic conditions in many prokaryotes, unicellular Eukaryotes and in germinating seeds
(4) Oxygen is the ultimate acceptor of electrones and it gets reduced to water
Which one of the given reaction does not involve decarboxylation?
1. ketoglutarate Succinyl CoA
2. Fumarate Malate
