Question

Cells often need to take in material from their environment, many of which are found in lower concentration outside the cell compared to inside the cell. In order to do this, cells must use the energy from ATP to move these materials.

Which option represents the correct process?

A. with the concentration gradient through passive transport
B. against the concentration gradient through active transport
C. against the concentration gradient through passive transport
D. with the concentration gradient through active transportCells often need to take in material from their environment, many of which are found in lower concentration outside the cell compared to inside the cell. In order to do this, cells must use the energy from ATP to move these materials.

Answer 1

The correct process for cells to move materials against the concentration gradient is option B: against the concentration gradient through active transport.

Step-by-step explanation:

Cells often need to take in material from their environment, many of which are found in lower concentration outside the cell compared to inside the cell. In order to do this, cells must use the energy from ATP to move these materials.

The correct process for cells to move materials against the concentration gradient is option B: against the concentration gradient through active transport. Active transport is the energy-requiring process of pumping molecules and ions across membranes 'uphill' - against a concentration gradient.
