Cohesion
Hydrogen Bonds occuring between water molecules.
1 of 15
Adehesion
Hydrogen bonds occuring between water and other molecules.
2 of 15
Osmosis
The net diffusion of water molecules through a semi-permeable membrane from a high concentration to a low concentration.
3 of 15
Diffusion
The movement of single molecules from a high concentration gradient to a low concentration gradient. (NB - no energy from ATP required)
4 of 15
Active Transport
The movement of molecules across a cell membrane from low concentration to high concentration, assisted by enzymes and requiring energy.
5 of 15
Carrier Proteins
These move large molecules into or out of a cell, down a concentration gradient.
6 of 15
Channel Proteins
These form pores in the membrane for charged particles to diffuse through, down a concentration gradient.
7 of 15
Glycosidic Bond
The bond that is made between two glucose molecules, formed in a condensation reaction.
8 of 15
Triglyceride
A lipid with one molecule of glycerol and 3 fatty acids.
9 of 15
Primary Structure of Protein
The sequence of amino acids in the polypeptide chain, held together by peptide bonds.
10 of 15
Secondary Structure of Protein
H-bonds form between amino acids in the chain, making the structure coil into an alpha helix or a beta pleated sheet.
11 of 15
Electrostatic Attraction
Attraction between a slightly positive atom and a slightly negative atom of another molecule.
12 of 15
Dipole
Separation of charge within a water molecule of slightly positive hydrogen atom and a slightly negative oxygen atom.
13 of 15
Surface Tension
Property of liquids, behaving as if the surface is covered by a thin elastic layer.
14 of 15
Amphoteric
Act as both an acid - forms H+ ions and is a proton acceptor and a base
