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

Which one is the correct sequence occurring in glycolysis?
1. G-6-P →PEP →3-PGAL →3-PGA
2. G-6-P →3-PGAL → 3-PGA →PEP
3. G-6-P →PEP →3-PGA →3-PGAL
4. G-6-P →3-PGA →3-PGAL →PEP

The dough kept overnight in warm weather becomes soft and spongy because of
1. Fermentation
2. Cohesion
3. Osmosis
4. Absorption of carbon dioxide from the atmosphere

During which stage in the complete oxidation of glucose, is the greatest number of ATP molecules formed from ADP?
1. Glycolysis
2. Krebs cycle
3. Electron transport
4. Conversion of pyruvic acid to acetyl CoA

Assertion: Catabolism in living organisms is linked to work by a chemical drive shaft – the ATP.
Reason: Exergonic catabolic pathways release energy that can directly be used for physiological functions.

1. Both assertion and reason are true and the reason is the correct explanation of the assertion.
2. Both assertion and reason are true but the reason is not the correct explanation of the assertion.
3. Assertion is true but reason is false.
4. Both assertion and reason are false.

Assertion: In general, organic molecules that have an abundance of hydrogen are excellent energy fuels for living organisms.
Reason: Bonds in such organic molecules are source of high energy electrons.

1. Both assertion and reason are true and the reason is the correct explanation of the assertion.
2. Both assertion and reason are true but the reason is not the correct explanation of the assertion.
3. Assertion is true but reason is false.
4. Both assertion and reason are false.
