Chapter 5: Q. 29 (page 154)

Where does the cell get energy for active transport processes?

Short Answer

Expert verified

The cell uses energy stored in it in the form of ATP (adenosine triphosphate).

Step by step solution

01

Step 1. Introduction 

Active transport is a process in which molecules or ions move from lower concentration to higher concentration against the concentration gradient.

02

Step 2. Explanation

The cell uses energy in the form of ATP to move the substances against its concentration gradient. Like if the substance concentration is higher inside the cell than outside (extracellular fluid) this movement of substances requires energy which is stored in the cell in the form of ATP.
