Question

what type of cell transport is pictured in the diagram below? a active transport because particles are moving without the use of atp. b passive transport because particles are moving against their concentration gradient. c passive transport because particles are moving with the use of atp. d active transport because particles are moving against their concentration gradient.

Explanation:

Active transport moves particles against their concentration gradient and requires energy in the form of ATP. In the diagram, ATP is shown being used and particles are moving against the concentration gradient. Passive transport occurs without ATP and with the concentration gradient.

Answer:

A. Active transport because particles are moving against their concentration gradient.
