|
what is the enzyme and product of starch |
amylase breaks down starch to sugars |
|
|
|
what is the enzyme and product of proteins |
protease breaks down protein to amino acids |
|
|
|
what is the enzyme and product of lipids (fats/oils) |
lipase breaks down lipids to fatty acids and glycerol |
|
|
|
how do enzymes work (3 steps) |
1)substrate collides with active site of enzyme-active site fits substrate 2)substrate joins active site to form enzyme/substrate complex 3)enzyme breaks down substrate to form products eg sugar |
|
|
|
denatured |
where the active sites shape is changed and cant fit substrate |
|
|
|
why are enzymes substrate specific |
so they can be re used so small concentrations of enzyme work on large quantities of substrate |
|
|
|
what affects enzymes shape |
pH- either side of the optimum ph change the shape of the active site & denature them (reversibly) temperature- either side of the optimum temperature will denature the enzyme (irreversibly) |
|
|
|
biological catalyst |
enzymes lower activation energy needed to start the reaction without being permanently changed |
|
|
|
exothermic |
chemical reactions that release energy |
external |
|
|
endothermic |
chemical reactions that absorb energy |
