Active Transport Energy Dependent Cell Transport Process

Subject : Biology

Question:

The type of cell transport that requires energy from the cell to move materials throughout the cell is:

A. mitosis

B. diffusion

C. passive transport

D. active transport

Expert Verified Solution:

The correct answer is D. active transport. Active transport is a process in which cells use energy, usually in the form of ATP, to move molecules across the cell membrane against their concentration gradient (from areas of lower concentration to areas of higher concentration). This is necessary for maintaining internal balance and for the functioning of many cellular processes.

Here’s a breakdown of the other options:

Mitosis (A): This is the process of cell division, not related to transporting materials within a cell.
Diffusion (B): Diffusion is a passive process where molecules move from an area of higher concentration to lower concentration without using energy.
Passive Transport (C): Like diffusion, passive transport does not require energy, as materials move along their concentration gradient.

Active transport plays a critical role in maintaining concentration gradients and transporting essential nutrients and ions into and out of cells.
