Introducing Enzymes (VCE SSCE Biology): Flashcards

Protein that speeds up specific reactions without being used up

Reactant in an enzyme-catalysed reaction

Part of enzyme where substrate binds

Structure formed when substrate binds to enzyme's active site

Enzyme changes shape to become complementary to substrate

Min. energy needed to energise molecules for a reaction

Smaller molecules combine to form a larger molecule

Larger molecule breaks down into smaller molecules

Enzyme names typically end with '-ase'

Remain unchanged after catalysing, can be used repeatedly
