Question

The transport of substance at the plasma lemma against the centration gradient is

Answer 1

The transport of substance at the plasma against the centration gradient is active transport.

Explanation:

• Active transport can be described as a process in which molecules move from a lower concentration to a higher concentration against the concentration gradient.
• As molecules moves against the concentration gradient, hence energy is required for this process to occur.
• The energy is usually utilized in the form of ATP for the process of active transport to occur.
• The process of active transport is opposite to the process of passive transport.

Answer 2

Explanation:

During active transport, substances move against the concentration gradient, from an area of low concentration to an area of high concentration. This process is “active” because it requires the use of energy (usually in the form of ATP). It is the opposite of passive transport.
