enzymes Flashcards
Definition of enzymes
Proteins that act as biological catalysts
Properties of enzymes
It is reusable, unchanged and they are substrates
definition of substrates
Substances that need to be moved
What is the collision theory on substrates
The different reactions acting at different rates
what are the 2 reasons collision theory needs to function properly
enough energy and orientation
Function of substrates
- Break down bigger molecules into smaller ones
- Combine smaller molecules to form bigger molecules
- Bring together different molecules to form new ones.
definition of specialised
It has a particular function
What is an active site in an enzyme
it is for binding
Protease and carbohydrase
lyases are a group of enzymes that break down bigger biological molecules.
Protease definition
Breaking down proteins to form amino acids
Carbohydrase definition
Breaking down carbohydrates to form simple sugars
Lipase defintion
Breaking down lipids to form glycerol and fatty acids.
What do enzymes need in order to function properly
Optimum pH and temperature
what happens when the speed of reaction increases in proteins
reduces activation energy
example of an enzyme
catalase (hydrogen peroxide -> water)
what happens when temperatures are too high
Enzyme breaks down
Definition of denaturation
Not able to bind with substrate in order to be a biological catalyst
Definition Of catalyst
Increases the rate of reaction without itself being changed.
