What are enzymes?
They are biological catalysts that speed up the rate of chemical reactions in living organisms.
Each enzyme can only catalyse one type of substrate molecule, they are specific
Resolution
The ability to define two individual points
I.AM triangle
Image size = Actual size x Magnification size
Actual size = Image size / Magnification size
Magnification size = Image size / Actual size
Nucleus
The nucleus controls the whole of the cells
Contains genetic information on the chromosomes.
Contains information for proteins to build new cells or organelles.
Cytoplasm
A liquid gel which suspends the organelles
Site where most reactions needed for life take place
Cell membrane
Controls the passage of substances in and out of the cell
Mitochondria
Structures in the cytoplasm where aerobic respiration takes place to create energy
Ribosome
Where protein synthesis takes place
Cell wall
Only present in plants
Made of cellulose to strengthen and give support to the plant
Vacuole
A space in the hole filled with cell sap to keep the cell rigid to support the plant
