General Enzyme Knowledge
Which of the following suggests that the shape of an enzyme determines the enzyme’s function?
A. Enzymes are specific to a substrate.
B. Enzymes can operate in a wide range of conditions
C. Enzymes are activated by neighboring molecules.
A. Enzymes are specific to a substrate.
Proteins that speed up chemical reactions
Enzymes
Enzymes _________ reactions in the cells.
What is speed up?
This is the term used when the enzyme is actively operating on the substrate causing the reaction.
What is an enzyme-substrate complex?
True or False: Enzymes are used up during their reaction.
False
Enzymes do not get used up. They are free to react again and again. This is why they are only need in the body in small amounts.
True or False: One enzyme can be used for many different types of reactions.
false
Enzymes can only react with one substrate
This is what the Enzyme acts upon.
What is a substrate?
Explain what is meant by "Enzymes are substrate specific"
What is they only react with certain substrates that fit into the active site. Think Lock and Key!
Enzyme that breaks down starch
Amylase
Enzymes lowers activation energy & speeds something up. Another word for this is a ____________.
catalyst
Where the specific substrate fits in the enzyme.
What is an active site?
Substances that bring about a chemical reaction without being changed.
Catalyst
An enzyme will ____________ the amount of activation energy required.
What is reduce?
The “new” substance created during reaction.
What is a product?
Amount of energy required for a chemical reaction to occur.
Activation energy
Substance formed from a substrate at the end of a chemical reaction with an enzyme.
Product
If enzymes are placed in a pH or temperature that is not optimal it will break apart or _______________
