- Enzymes
- what is a enzyme?
- A Biological Catalyst.
- Speeds up chemical Reactions in living organisms.
- some work inside cell, others outside cell.
- pH and Temperature effect how well these enzymes work.
- Speeds up chemical Reactions in living organisms.
- A Biological Catalyst.
- Different Functions
- Respiration
- Digestion
- Photosynthesis
- Building Large Molecules e,g protein synthesis
- Has it own shape.
- Because, Unique sequence of amino acids.
- Shape is vital to its function.
- within the shape a little area is formed call ed theactive site.
- this is where another molecule can fit during a reaction (substrate)
- shape pf active site has to be complementary to the shape of substrate i.e lock and key.
- if shape is changed it will not work.
- denatured - when active site is damaged.
- if shape is changed it will not work.
- shape pf active site has to be complementary to the shape of substrate i.e lock and key.
