Enzymes Flashcards
How can you make a reaction happen more quickly
Raising the temperature
What is a catalyst
A substance which increases the speed of a reaction without being changed or used up in the reaction
What are enzymes
All proteins and proteins are made up of chans and amino acids
What else do proteins act as other than catalysts
Structural components of tissues, hormones and antibodies
There is a limit to how far you can raise the temper inside a living creature before its cells start to
Get damaged
What do chemical reactions usually involve
Being split apart or joined together
How many reactions do enzymes usually catalyse
One reaction
What will happen if the substance doesn’t match the enzyme’s shape
The reaction won’t be catalysed
What do enzymes need
The right temperature and pH
What does changing the temperature do
Changes the rate of an enzyme catalysed reaction
If an enzyme gets too hot what happens
Some of the bonds holding the enzymes together break
What temperature in the human body do enzymes work best at
37 c
What enzyme is used to break down proteins in the stomach
Pepsin
What are enzymes
Catalysts produced by living things
