NEET BIOLOGY

Detailed explanation-1: -Solutes move against the concentration gradient, therefore energy is needed. Q. What is it called when molecules move across the cell membrane from an area of high concentration to an area of low concentration through a carrier protein?

Detailed explanation-2: -In active transport, the molecules move against the concentration gradient whereas in passive transport, the molecules move along the concentration gradient.

Detailed explanation-3: -Solutes move with the concentration gradient, therefore no energy is used. Movement of materials from high to low concentration through a protein channel.

Detailed explanation-4: -Passive transport does not require the cell to expend any energy and involves a substance diffusing down its concentration gradient across a membrane.

Detailed explanation-5: -Passive transport is a type of cellular transport in which substances such as ions and molecules move down their respective concentration gradients. It means that the substance tends to move from an area of higher concentration to an area of lower concentration.
