Question

The main difference between active and passive transport across cell membrane is

विकल्प

• active transport occurs more rapidly than passive transport.

• passive transport is non-selective whereas active transport is selective.

• passive transport requires a concentration gradient across a biological membrane whereas active transport requires energy to move solutes.

• passive transport is confined to anionic carrier proteins whereas active transport is confined to cationic channel proteins.

Answer 1

passive transport requires a concentration gradient across a biological membrane whereas active transport requires energy to move solutes.

Explanation:

Active transport involves the movement of materials across a biological membrane using a carrier protein and ATP, whereas passive transport involves the movement of substances along a concentration gradient, i.e. from a higher concentration area to a lower concentration area.
