Question

What is one similarity between active and passive transport?

Answer 1

Answer:

The correct answer is both involve moving substance across the membrane.

Explanation:

Passive transport is one of the most important membrane transport process which helps in transport of polar molecules and gases along their concentration gradient across the plasma membrane.No addition energy is required to carry out passive transport because during passive transport molecules move from high concentration region to the region of low concentration.

Active transport is a specific type of membrane transport process which helps in the passage of ions against their concentration gradient across the plasma membrane.As the ions are moving against their concentration gradient additional chemical energy is required to carry out their uphill transport.
