What is the role of the plasma membrane?
allows movement of the cell
regulates the substances which enters and leaves the cell
receives the molecules which carry information
centre of the cell
The rough endoplasmic reticuli
manufactures fatty acids, steriods and phospholipids
maufactures DNA
manufactures adenosine triphosphate
manufactures and stores protein for the plasma membrane
What does passive transport refer to?
a cell's ability to allow the entry and exit of some materials in ways other than through channels and transporters
a cell's ability to allow the entry and exit of some materials through channels and transporters
a cell's ability to use energy in order to transport materials

What is myelin?
a sugar that is created by a cell
the energy molecule produced by the mitochondria
a fatty substance surrounding the axon that 'speeds up' the action potential
a waste product of creating ATP
Synapse is the name for the gap that exists between an axon terminal and either
the dendrites of another neuron
the axon terminal of another neuron
a muscle
a gland
