ATP energy made and used by the body
ATP is made in the mitochondria
Enzymes protein; biological catalyst that controls the speed of reactions
substrate what the enzyme works on (breaks apart)
active site the opening of the enzyme where the substrate fits
enzyme substrate complex enzyme and substrate together
lock and key theory the enzyme will only work on one type of substrate; they are substrate specific
products broken pieces of the substrate
denature the active site changes if too warm or pH is too high
3 things that affect an enzyme temperature, pH, concentration
optimum the best temperature, pH or concentration; where the enzyme works the best
