Examples of this macromolecule are DNA and RNA.
What is nucleic acids?
400
The term for the reactant that enzymes act on.
What is substrate?
400
This is the part of the cell membrane that moves large molecules into and out of the cell.
What is proteins.
400
This type of transport moves down the concentration gradient and also uses a channel protein.
