Question

Cells occasionally need to take in or drink large amounts of water, this process is called pinocytosis. How does this process differ from osmosis?

a it is passive transport, and moves against the concentration gradient.
b pinocytosis involves only bacteria, and is rarely observed
c it is active transport, and moves against the concentration gradient.
d it is also called exocytosis

Answer 1

C. It is active transport, and moves against the concentration gradient.

Explanation: Pinocytosis is an active transport in which the molecules move from a low to a more higher concentration gradient. During this process it requires energy to move molecules and the energy used is ATP.
