Chapter 27, Problem S5.4BYB

Section 5.4 How does active transport move molecules and ions against their concentration gradients?

Summary Introduction

To determine:

The process of how active transport moves molecules and ion against their concentration gradients.

Given:

Active transport move molecules and ion against their concentration gradients.

Introduction:

Active transport is a process of transport in which ions or molecules can be transported against the concentration gradient in which energy requirement is fulfilled by the ATP

Explanation of Solution

The Na+K+ATPase is an enzyme which bring the breakdown of ATP to release energy to move ions against their concentration gradient from higher concentration to lower concentration.

Conclusion

During active transport the cell must uses energy in the form of ATP, to move substances against a concentration gradient.
