what a reactant is called when it binds to an enzyme
What is a substrate?
200
area on an enzyme where a substrate and an enzyme bind
What is active site?
200
energy of position
What is potential energy?
300
In this activity chemical bonds are broken and new bonds are formed
What is a chemical reaction?
300
Where ATP stores energy in its bonds
What is between the phosphates?
300
what happens to enzymes after a chemical reaction
What is unchanged?
300
this type of chemical reaction releases energy into the environment
What is exergonic?
300
this molecule is made up of a nitrogen base, a five carbon sugar, and 3 phosphate groups
What is ATP?
400
In this type of reaction products have more energy than reactants
What is endergonic?
400
the potential energy available for release in a chemical reaction
What is chemical energy?
400
A graph shows 2 different lines for the same reaction, one line shows the reaction with an enzyme present and one line shows the reaction without an enzyme present. Describe the difference between the lines.
What is one line has a lower activation energy?
400
These compete with substrates to bind with enzymes
What are inhibitors?
400
List 2 factors that affect enzyme activity
What are temperature, pH, cofactors, inhibitors, ionic salts?
500
the energy needed to start a chemical reaction
What is activation energy?
500
type of reaction that the synthesis of ATP is
What is endergonic?
500
This is the reason heating an enzyme prevents it from functioning correctly
What is changes the enzymes shape?
500
the use of energy from an exergonic reaction to drive an endergonic reaction
What is a coupled reaction?
500
These resemble an enzyme's normal substrate compete with it for the active site
