Question

type of transport?
how do you know?

Explanation:

The image shows molecules moving against their concentration gradient (from low to high concentration) and the use of ATP (adenosine triphosphate). Active transport is the process where substances move against their concentration gradient and requires energy (in the form of ATP).

Answer:

Type of transport: Active transport.
How do you know: Molecules are moving against the concentration gradient (from low to high) and ATP is being used (as indicated by the conversion of ATP to ADP + P).
