Formation of glycosidic bond represents:

1. Dehydration	2. Hydrolysis
3. Dehydrogenation	4. Isomerization

Most hydrated and most stable form of DNA is known as:

Assertion: Enzymes are usually much larger than their substrates.

Reason: Only a small portion of their structure makes up their active sites.

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: Enzymes are biochemical catalysts that speed up a chemical reaction by lowering the activation energy required for a reaction to proceed.

Reason: Enzyme either brings substrates together in the correct orientation or stress particular chemical bonds of a substrate.

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  competitive inhibition, the substrate and inhibitor cannot bind to the enzyme at the same time.

Reason: This type of inhibition can be overcome by sufficiently high concentrations of substrate (Vmax remains constant).

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: ATP is a nucleoside triphosphate.

Reason: It has three high energy bonds that can be broken to drive biochemical processes in the cell.

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: All amino acids share amphiprotic properties.

Reason: All amino acids contain amine and carboxylic acid functional groups.

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: Protein denaturation is always irreversible.

Reason: A denatured protein cannot be renatured.

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: There are nine essential amino acids which humans must obtain from their diet in order to prevent protein-energy malnutrition and resulting death.

Reason: Histidine is not synthesized in adults.

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: Strictly speaking proteins are made up of amino acid residues rather than amino acids.

Reason: When a peptide bond is formed, a water molecule is lost.

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
