Explain the shape of a graph in terms of particle theory that shows how temperature afects enzyme action
|
As the temperature increases the particles gain energy. They collife more and react more. The rate of the reaction increases. Acts 40 degrees then the enzyme denatures

|
Define Diffusion
|
Diffusion is the movement of molecules from region of their higher cocentration to their region of their lower concentration down a concentration gradient
|
|
|
Define Enzyme
|
-They are made up of protein
-They are macro molecules - They are biological catalysts - They speed up the rate of reaction without being change |
|
|
Define Active Transport
|
- An energy consuming process
- Moves substances against their concentration gradient e.g Magnesium Ion uptake by root hair cells |
|
|
Define Osmosis
|
- Net movement of water molecules from their higher concentration to their lower concentration across semi-permeable membrane
