(2) ATPase

(3) Phosphorylase

(4) Catalase

(2) G-6-P $\to$3-PGAL $\to$ 3-PGA $\to$PEP

(3) G-6-P $\to$PEP $\to$3-PGA $\to$3-PGAL

(4) G-6-P $\to$3-PGA $\to$3-PGAL $\to$PEP

In which of the following reactions of glycolysis, a molecule of water is removed from the substrate?
(a) Glucose $\to$ Glucose-6-phosphate
(b) Fructose-6-phosphate $\to$ Fructose-1,6 bisphosphate
(c) 2-phosphoglycerate $\to$Phosphoenol pyruvate

Aerobic respiration produces more usable chemical energy than fermentation, because fermentation involves
(1) formation of lactic acid 

(2) complete oxidation of food

(3) partial oxidation of food 

(4) evolution of CO₂ and alcohol

RQ (Respiratory Quotient) is defined as

(1) $\mathrm{Volume} \mathrm{of} {\mathrm{CO}}_2 \mathrm{evolved} = \mathrm{Volume} \mathrm{of} {\mathrm{O}}_2 \mathrm{consumed}$

(2) $\frac{\mathrm{Volume} \mathrm{of} {\mathrm{O}}_2 \mathrm{consumed}}{\mathrm{Volume} \mathrm{of} {\mathrm{CO}}_2 \mathrm{evolved}}$

(3) $\frac{\mathrm{Volume} \mathrm{of} {\mathrm{CO}}_2 \mathrm{evolved}}{\mathrm{Volume} \mathrm{of} {\mathrm{O}}_2 \mathrm{consumed}}$

(4) $\frac{\mathrm{Volume} \mathrm{of} {\mathrm{O}}_2 \mathrm{evolved}}{\mathrm{Volume} \mathrm{of} {\mathrm{CO}}_2 \mathrm{consumed}}$

The colour in the brown fat is due is
(1) its larger capacity for generating heat

(2) large number of mitochondria present

(3) a high concentration of iron containing cytochrome pigments

(4) presence of chromatophores

Cell respiration is carried out by 

(1) ribosome 

(2) mitochondria

(3) chloroplast

(4) Golgi bodies

The process by which ATP is produced in the inner membrane of a mitochondrion. The electron transport system transfers protons from the inner compartment of the outer; as the protons flow back to the inner compartment, the energy of their movement is used to add phosphate to ADP, forming ATP.
(1) Chemiosmosis

(2) Phosphorylation

(3) Glycolysis

(4) Fermentation

After glycolysis, fate of glucose in mitochondrial matrix is

(1) oxidation

(2) reduction

(3) oxidative decarboxylation

(4) hydrolysis.

Which of the following is true regarding the given electron transport chain?
$\mathrm{CoQ} \to \mathrm{Cyt} \mathrm{c} \to \mathrm{Cyt} {\mathrm{aa}}_3\to {\mathrm{O}}_2$
$\left(\mathrm{a}\right) \mathrm{CoQ} \to \mathrm{Cyt} \mathrm{c} \mathrm{is} {\mathrm{H}}^{+} \mathrm{absorbing} \mathrm{site}.$
$\left(\mathrm{b}\right) {\mathrm{aa}}_3 \to {\mathrm{O}}_2, {\mathrm{H}}^{+} \mathrm{yielding} \mathrm{site}.$
$\left(\mathrm{c}\right) \mathrm{CoQ} \to \mathrm{Cyt} \mathrm{c} \mathrm{is} {\mathrm{H}}^{+} \mathrm{yielding} \mathrm{site} \mathrm{and} {\mathrm{aa}}_3\to {\mathrm{O}}_2 \mathrm{is} {\mathrm{H}}^{+} \mathrm{absorbing} \mathrm{site}.$
$\left(\mathrm{d}\right) \mathrm{No} {\mathrm{H}}^{+} \mathrm{is} \mathrm{absorbed} \mathrm{or} \mathrm{released}$
