Match the modes of transport to the molecules. There are carrier proteins, osmosis, active transport, simple diffusion, exocytosis and I have to drag them to oxygen, water molecule, charged amino acid, calcium moves from low concentration to high concentration, protein from the Golgi apparatus. What goes where?

The answers are:
carrier proteins → charged amino acid     
Carrier proteins are transmembrane proteins for the facilitated diffusion of charged amino acids across plasma membranes.

osmosis → water molecule
A type of passive transport, osmosis is the diffusion of water molecules in and out of cells.

active transport → calcium moves from low concentration to high concentration
This is the movement of substances across membranes against concentration gradient.

simple diffusion → oxygen
Oxygen molecules enter through membrane by simple diffusion from an area of high to low concentration.

exocytosis → proteins from the Golgi apparatus 
This process of exocytosis is used by cells to release particles that has been packaged by the golgi bodies.
