1An enzyme is...
- AA substrate
- BA biological catalyst
- CA reactant
2A catalyst is a substance that speeds up the rate of a chemical reaction but is not itself changed by the reaction.
- AVerdadero
- BFalso
3Which of the following words are related to enzymes?
- ACatalyst
- BCatalogue
- CReactor
- DSubstrate
- EReactant
- FPhosphosulface Pentithroene
4Enzymes are [blank_start]biological catalysts[blank_end] made up on long chains of [blank_start]amino acids[blank_end]. These long chains fold to produce a [blank_start]special[blank_end] shape which is vital for the enzyme’s [blank_start]function[blank_end].
- Abiological catalysts
- Bhypogenical catalysts
- Camino acids
- Dtrisulfic acids
- Efunction
- Fklorific
- Gspecial
- Hlovely
5In the same way that a [blank_start]key fits into a lock[blank_end], so a substrate (another name for the [blank_start]reactants[blank_end]) is thought to fit into an enzyme’s [blank_start]active site[blank_end]. The enzyme is the lock and the reactant is the key.
- Akey fits into a lock
- Bhand fits into a shoe
- Cpencil fits into a penlid
- Dcore
- Ereactor
- Freactants
- Gpentacarbonixyin
- Hphospholyn
- Ibusy area
- Jactive site
6Starch is digested by [blank_start]amylase[blank_end]. Salivary amylase is produced in the [blank_start]salivary glands[blank_end] and released into the mouth in saliva. This also contains water and mucus. Amylase is also produced by the [blank_start]pancreas[blank_end] and released into the [blank_start]duodenum[blank_end], part of the small intestine (slightly [blank_start]acidic[blank_end] pH).
- Aamylase
- Bsalivary glands
- Cpancreas
- Dduodenum
- Eacidic
