Enzymes Flashcards
What is an enzyme
They are biological catalysts
What is a catalyst
It is a chemical which speeds up a reaction without being used up itself. This means that they can be reused repeatedly and are therefore effective in small amounts.
What temperature works best for an enzyme
They work best at 37c
What would happen if enzymes didn’t exist
Chemical reactions in the body would occur too slowly to sustain life as we know it.
Enzymes are biological catalysts why are they catalysts
They are catalysts since they increase the rate of a reaction without undergoing permanent change. This means enzymes can be reused repeatedly and are therefore effective in small amounts.
What is a protein
enzymes are large protein molecules.
What is an active site
a specific area of enzyme that is shaped to allow
other molecules to fit into it to undergo reaction. Most vital
part of enzyme function.
What is a substrate
the molecule that fits into the active site to
undergo reaction.
What is an Enzyme-substrate complex:
the structure formed when the
substrate and enzyme bind together for the reaction
What is a product
What is formed after the reaction
