1 – Carrier Protein vs. Channel Protein
Carrier Protein – Changes shape to move specific molecules in or out of the cell.
2 – Cell Membrane Structure
– Globular Proteins
– Carbohydrate Sugar Chain
– Hydrophillic Heads
– Cell Membrane Receptor Proteins
– Integral Membrane Proteins
– Peripheral Membrane Proteins
– Hydrophobic Tail
– Phospholipid Bilayer
3 – Channel Protein Definition & Function
Carrier-mediated transport. – the process by which molecules pass through a membrane via a channel protein.
– Plasma membrane
– Water Soluble Molecules
– Fat Soluble Molecules
4 – Chemistry of Proteins
Proteins are organic compounds with a high molecular weight formed of carbon, oxygen, hydrogen & nitrogen & may also contain phosphorous, sulphur, colouring non-protein organic groups & metal ions.
They are polymers formed of sub-units called amino acids linked together by peptide linkage.
5 – RNA – DNA Structures
6 – Proteins – Primary, Secondary, Tertiary & Quarternary Structures
Primary Structure – amino acid sequence.
Secondary Structure – regular sub-structures
Tertiary Structure – three dimensional structure.
Quarternary Structure – complex of protein molecules
