7 / 10

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

Assertion: Membrane transport occurs through the carrier proteins.

Reason: The transport carried by carrier proteins is always passive.

8 / 10

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

Assertion: Lysosomes posses’ acidic pH.

Reason: Lysosomes are rich in hydrolytic enzymes which are activated by acidic pH.

9 / 10

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

Assertion: In lipid bilayer in membrane, lipid are arranged with polar head towards outer side and the hydrophobic tail towards the inner part
