Enzymes
What are they?
How they function?
Factors affecting it
Vocabulary
Enzymes are large proteins that are biological catalysts of a reaction.
They speed up or slow down a reaction
Reactions that take place in our body are part of a process called metabolism.
All enzymes end with "ase"
Don't change form when used
Denaturing
Biomolecules
Reactions
Importance
Enzymes work in a lock and key mechanism
The substrate holds on to the active site
pH level Some enzymes work in acidic condition, some enzymes work in basic conditions. Changes in ph change the change of the protein
Temperature Increase in temperature can cause enzymes to denature. Decrease causes molecules to move slower.
Carbohydrates- Glucose
Protein - Amino acids
Lipids - Fatty acids/glycerol
Nucleic acid - nucleic acid
Reaction only occurs when substrate and active site collide
99% of reactions in our body depend on enzymes. If they are not present, these reactions wont take place.
Reactions that take place without enzymes will be a lot slower than supposed to be
Denaturing causes the enzyme to stop functioning
Shape matters for enzymes. Denaturation is a permanent change in the shape of the enzyme
Enzymes work in a lock & key mechanism
