Enzymes Flashcards
What are enzymes made from?
Protein
Where are enzymes made in a cell?
Ribosomes
What does the term optimum mean?
The condition at which the enzyme is most active.
What is the optimum temperature for enzymes?
37-40 (check the graph)
What term is used to describe the fact that an enzyme will only react with one substrate?
Specific
What name is given to the chemical the enzyme reacts with?
Substrate
Which part of the enzyme does the substrate have a complementary shape with?
Active site
Why are enzymes described as biological catalysts?
- They speed up chemical reactions
- They do not get used up
- They are found inside living cells
What term is used to describe a reaction where the product is smaller than the substrate?
Degradation
What term is used to describe a reaction where the product is larger than the substrate?
Synthesis
Give an example of a degradation reaction.
SAM
Starch is broken down by amylase to produce maltose
Give an example of a synthesis reaction.
GPS
Glucose-1-phosphate is built up by phosphorylase to produce starch.
What happens to an enzyme when it becomes too hot?
Denatures
What does the term denatured mean?
A change in the shape of the enzymes active site
What name is given to the chemical made at the end of the reaction?
Product
