Enzymes Flashcards
A catalyst is
A chemical that speeds up a chemical reaction without being changed by it
When a catalyst is present
Less energy is needed for a chemical reaction
An enzyme is
A biological catalyst
Enzymes are made of
Protein found in all living cells
Without enzymes…
Reactions in our body would not happen quick enough
All enzyme reactions followed this word equation
Enzyme
Substrate ——> product
What is meant when enzymes are said to be specific
It means an enzyme can only work on one specific substrate
An enzyme has its own unique…
Shape
An enzymes shape is
Complimentary to its substrate
Like a lock and key
The place where the enzymes and substrates fit tight is the
Active site
Some examples of break down reactions are…
SAM HP.COW P3 FLAG G1PPS
The optimum temperature is
The temperature at which an enzyme works best
At high temperatures enzymes are
Denatured
Some examples of break down enzyme reactions are
Hydrogen peroxide + catalase = oxygen +water
Starch + amylase = maltose
Protein + pepsin = peptides
Fat + lipase = fatty acids+ glucose
Some examples of build up enzyme reactions are
Glucose-I-phosphate + phosphorylase = starch
