- Membrane Components
- Glycolipids and Glycoproteins
- act as receptor sites
- hormones can bind to them
- drugs can bind to them
- stimulate a response within the cell
- hormones can bind to them
- stimulate a response within the cell
- involve in cell signalling in the immune system
- Intrinsic Proteins
- are channel proteins
- Transport Proteins
- allow movement of molecule that are normally too larger or too hydrophilic to pass through the membrane by forming a tube-like structure that goes through the whole membrane
- Transport Proteins
- Carrier Proteins
- use energy in the form of ATP
- move substances across the membrane
- Enzymes and Coenzymes
- attached in order to carry out metabolic reactions
- Cholesterol
- provides strength
- stability by reducing fluidity
- making bilayer more complete
- Glycolipids and Glycoproteins
