chemical reactions in enzymes

what are chemical reactions

they are a process that changes one compound or compounds into another

Reactants

The elements or compounds that engage the reaction

Products

The elements or compounds that are produced in the reaction

in ALL chemical reaction one of two MUST happen

1. energy is released (these reactions occur on their own

2. Engery is absorbed ( these reactions require an energy source

Activation energy

The energy needed to get a reaction started and energy is required no matter if a reaction is energy releasing or energy storing reaction

what is the purpose of enzymes

enzymes serve as catalysts in our bodies making reactions speed up

are enzymes used up

Enzymes are not used up since they can be used over nd over again

Without enzymes reactions occur tooo slow to carry on life

what are enzymes

Enzymes are natures catalyst and are almost always proteins

do shapes matter in ezymes

Enzymes are reaction specific because they fir ( protein shake is important) into specific parts of the reaction

what is an active site

Active site is a site where reactants can be brought together

Substrate

the reactants if a chemical reaction that has an enzyme available

the fit is very precise (lock and key)

What if the enzyme isn’t there

the reaction cannot occur quickly enough

what is very important to enzymes

the shape of the enzyme is very sensitive to changes in pH and temperature

denaturing

if either one of them changes the shape of the enzyme and the key will no longer fit the lock preventing the reaction from occurring
