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.
