Glycolysis is found in cytoplasm of virtually all types of aerobic/anaerobic cells. In this

process, glucose is converted into :

1. PEP

2. acetyl CoA

3. pyruvic acid

4. citric acid.

Which of the following is the connecting link between glycolysis and Krebs cycle?
(1) Acetyl Co-A

(2) Oxalosuccinic acid

(3) Pyruvic acid

(4) Citric acid 

The enzyme decarboxylase catalyses the following step
(1) conversion of citric acid to cis aconitic acid

(2) fumaric acid to malic acid

(3) oxalosuccinic acid to o-ketoglutaric acid

(4) malic acid to oxaloacetic acid.

Which of the following is true regarding the given electron transport chain?

$\left(\mathrm{a}\right) \mathrm{CoQ} \to \mathrm{Cyt} \mathrm{c} \mathrm{is} {\mathrm{H}}^{+} \mathrm{absorbing} \mathrm{site}.$
$\left(\mathrm{b}\right) {\mathrm{aa}}_3 \to {\mathrm{O}}_2, {\mathrm{H}}^{+} \mathrm{yielding} \mathrm{site}.$
$\left(\mathrm{c}\right) \mathrm{CoQ} \to \mathrm{Cyt} \mathrm{c} \mathrm{is} {\mathrm{H}}^{+} \mathrm{yielding} \mathrm{site} \mathrm{and} {\mathrm{aa}}_3\to {\mathrm{O}}_2 \mathrm{is} {\mathrm{H}}^{+} \mathrm{absorbing} \mathrm{site}.$
$\left(\mathrm{d}\right) \mathrm{No} {\mathrm{H}}^{+} \mathrm{is} \mathrm{absorbed} \mathrm{or} \mathrm{released}$

After glycolysis, fate of glucose in mitochondrial matrix is

(1) oxidation

(2) reduction

(3) oxidative decarboxylation

(4) hydrolysis.

Which enyme helps in transfer of phosphate group from ATP to carbohydrate?

(1) Phosphate

(2) ATPase

(3) Phosphorylase

(4) Catalase

Which one is correct sequence occuring in glycolysis?
(1) G-6-P $\to$PEP $\to$3-PGAL $\to$3-PGA

(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
(d) Phosphoenol pyruvate $\to$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
