Question

1. active transport includes

active transport mechanisms include:
and
diffusion

Explanation:

Active transport is the movement of molecules across a cell membrane from an area of lower concentration to an area of higher concentration against the concentration gradient, requiring energy. The main active - transport mechanisms are primary active transport (which directly uses energy, like ATP) and secondary active transport (which uses the energy stored in an electrochemical gradient established by primary active transport). Diffusion is a passive transport process and not an active - transport mechanism.

Answer:

Primary active transport; Secondary active transport
