1Enzymes are biological [blank_start]catalysts[blank_end] which means that they [blank_start]speed up[blank_end] the rate of reaction [blank_start]without[blank_end] being used up.
- Acatalysts
- Bspeed up
- Cwithout
2Enzymes are made of [blank_start]protein[blank_end] molecules.
- Aprotein
3Enzymes work best at an [blank_start]optimum[blank_end] PH and temperature. At lower temperatures the enzyme will work more [blank_start]slowly[blank_end]. At higher temperatures the enzyme becomes [blank_start]denatured[blank_end] and will not work at all. This is because its [blank_start]active site[blank_end] has changed.
- Aoptimum
- Bslowly
- Cdenatured
- Dactive site
4Enzymes are important in digestion because they break down [blank_start]large[blank_end] molecules into [blank_start]small[blank_end] molecules. This is important so that food can be made small enough to be absorbed through the wall of the [blank_start]gut[blank_end] into the [blank_start]blood[blank_end].
- Alarge
- Bsmall
- Cgut
- Dblood
5Enzymes are [blank_start]specific[blank_end] which means they will only work with [blank_start]one[blank_end] substrate. For example the enzyme amylase will only work to break down [blank_start]starch[blank_end] into maltose.
- Astarch
- Bspecific
- Cone
6Amylase is a [blank_start]carbohydrate[blank_end] enzyme, as it breaks down [blank_start]carbohydrates[blank_end].
- Acarbohydrate
- Bcarbohydrates
7[blank_start]Protein[blank_end] enzymes break down protein into amino acids and lipase enzymes break down [blank_start]lipids[blank_end] into fatty acids and [blank_start]glycerol[blank_end].
- AProtein
- Blipids
- Cglycerol
