The chemiosmotic coupling hypothesis of oxidative phosphorylation proposes that Adenosine Triphosphate (ATP) is formed because
1. high energy bonds are formed in mitochondrial proteins
2. ADP is pumped out of the matrix into the intermembrane space
3. a proton gradient forms across the inner membrane
4. there is a change in the permeability of the inner mitochondrial membrane toward Adenosine Diphosphate (ADP)

Which one of the following mammalian cells are not capable of metabolising glucose to carbon dioxide aerobically?

All enzymes of TCA cycle are located in the mitochondrial matrix except one which is located in inner mitochondrial membranes in eukaryotes and in cytosol in prokaryotes. This enzyme is
1. lactate dehydrogenase
2. isocitrate dehydrogenase
3. malate dehydrogenase
4. succinate dehydrogenase

The overall goal of glycolysis, Krebs cycle and the electron transport system is the formation of:
1. ATP in small stepwise units
2. ATP in one large oxidation reaction
3. Sugars
4. Nucleic acids

How many ATP molecules could maximally be generated from one molecule of glucose, if the complete oxidation of one mole of glucose to ${\mathrm{CO}}_2$ and ${\mathrm{H}}_2\mathrm{O}$ yields 686 kcal and the useful chemical energy available in the high energy phosphate bond of one mole of ATP is 12 Kcal?

In respiration from 180g of glucose, which of the following is formed?
1. 264gm ${\mathrm{CO}}_{\mathrm{2 }}$+190gm ${\mathrm{H}}_2\mathrm{O }$+ 391 Kcal
2. 264gm ${\mathrm{CO}}_{\mathrm{2 }}$+108gm ${\mathrm{H}}_2\mathrm{O }$+ 686 Kcal
3. 390gm ${\mathrm{CO}}_{\mathrm{2 }}$+108gm ${\mathrm{H}}_2\mathrm{O }$+ 686 Kcal
4. 390gm ${\mathrm{CO}}_{\mathrm{2 }}$+ 264gm ${\mathrm{H}}_2\mathrm{O }$+ 391 Kcal

Glycolysis is found in the cytoplasm of virtually all types of aerobic/anaerobic cells. In this process, glucose is converted into :

Which of the following is the connecting link between glycolysis and Kreb's cycle?

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 $\mathrm{\alpha }$-ketoglutaric acid
4. malic acid to oxaloacetic acid

After glycolysis, the fate of glucose in the mitochondrial matrix is
1. oxidation
2. reduction
3. oxidative decarboxylation
4. hydrolysis
