• ENZYMES - Found in Cytoplasm, speeds up and controls chemical reactions.
• CYTOPLASM - Gel-like substance where most of the chemical reactions happen. It contains Enzymes that control these chemical reactions
• CELL MEMBRANE - Holds the cell together and controls what goes in and out.

• RIBOSOMES - These are where proteins are made in the cell.
