Question

Assertion :Glucose, $N{a}^{+}$ and amino acids are absorbed actively. Reason: $N{a}^{+}$, glucose and amino acids move against the concentration gradient and hence require energy.

• A. both assertion and reason are true and reason is the correct explanation of assertion.
• B. both assertion and reason are true but reason is not the correct explanation of assertion
• C. assertion is true but reason is false.
• D. both assertion and reason are false.

Answer 1

The correct option is A both assertion and reason are true and reason is the correct explanation of assertion.

Glucose, sodium, and amino acids are absorbed by active absorption, they move against the concentration gradient so it requires energy.

So, the correct option is 'both assertion and reason are true and reason is the correct explanation of assertion.'.
