Active Transport: The Energy Source of Cells

What type of energy do cells use to perform active transport?

a. mechanical energy

b. ATP energy

c. thermal energy

Answer:

Cells use ATP energy to perform active transport.

Cells use ATP energy to perform active transport. Active transport is the process by which cells move molecules across the cell membrane against the concentration gradient, requiring the input of energy. ATP, or adenosine triphosphate, is the energy currency of cells and is used to fuel various cellular processes, including active transport.

In active transport, ATP provides the energy needed to pump molecules or ions from an area of low concentration to an area of high concentration.

Therefore, ATP energy is crucial for the functioning of cells in performing active transport and maintaining cellular processes.
