10 Random question from this chapter are displayed, you can take the quiz multiple times to cover all questions

1 / 10

Read the assertion and reason carefully to mark the correct option out of the options given below:

Assertion: Fermentation and aerobic respiration generate different amount of ATP.

Reason: Fermentation leads to partial breakdown of glucose where as aerobic respiration lead to complete breakdown of glucose into CO2 and H2O which generate more amount of energy.

Both (A) and (R) are true and (R) is not correct explanation of the assertion

(A) is true but (R) is false

Both (A) and (R) are false

(A) is true but (R) is false

Both (A) and (R) are false

6 / 10

Read the assertion and reason carefully to mark the correct option out of the options given below:

Assertion: Substrate level phosphorylation is present in glycolysis.

Reason: Substrate level phosphorylation causes synthesis of ATP.

Both (A) and (R) are true and (R) is correct explanation of the assertion

Both (A) and (R) are true and (R) is not correct explanation of the assertion

(A) is true but (R) is false

Both (A) and (R) are false

7 / 10

Read the assertion and reason carefully to mark the correct option out of the options given below:
