What is an enzyme?
A molecule made up of proteins that help speed up chemical reactions
100
In order for a reaction to occur ___________ is needed.
Energy
100
In a chemical reaction we have ___________ and __________ that are separated by an arrow to show a change.
Reactants and products
100
What model did we say enzymes and substrates are like?
Lock and key model
100
The _________ of the active site determines which substrates will bind to it
shape
200
What happens in a chemical reaction?
Bonds are broken and formed
200
What is the conservation of mass?
Matter cannot be created or destroyed
200
What is the conservation of energy?
Energy can be changed but never destroyed or created
200
The molecule that interacts with enzymes is called what?
The substrate or reactant
200
What is the top line pointing to?
Substrate
300
What is energy?
The ability to move or change matter
300
What is a reactant?
the substance that is changed in a chemical reaction (what you start with)
300
What is a product?
The new substance created by the chemical reaction (the end result)
300
The place where substrates bind to enzymes
active site
300
What is the middle line pointing to?
Active site
400
Reactions can only occur if these two things occur, what are they?
Atoms are aligned properly, and activation energy is available
400
In order to make sure that large molecules or reactions needing large amount of activation energy get done, what is used?
enzyme
400
This is what an enzyme and substrate together is called
Enzyme-substrate complex
400
How inhibitors work on enzymes
They bind to the active site to block substrate from entering
400
What is the bottom line pointing to?
Enzyme
500
How do enzymes help speed up reactions? (2 answers)
Lower activation energy
Hold molecules in the perfect position
500
This is the process that happens when enzymes break apart molecules
Catalysis
500
What 4 things affect how well enzymes work?
Temperature, pH levels, activators, and inhibitors
500
True or false: All inhibitors are detrimental to the function of enzymes since they need to be working.
False
500
Without enzymes reactions would not occur as _______________, _____________, or ______________.
Frequently, quickly, or easily
