Topic 3.1 - Enzyme Structure 𖦹⋆｡°✩ Flashcards
what are enzymes
biological catalysts that speed up biochemical reactions (proteins)
what shape are most enzymes and why must it be maintained
tertiary shape must be maintained for functionality. they also have active sites
what is a substrate
a molecule that can interact with an enzyme
༻ has a unique shape and size
༻ can have chemical change(s) or not
what specifically reacts with substrates
the active site that enzymes have
what must happen for a substrate and active site to react
physical and chemical properties of the substrate must be compatible, but slight changes can occur to align with the substrate
what do enzyme names indicate
the substrate or chemical reaction involved
what do enzyme names often end in. provide an example
enzyme names often end in -ase. for example, sucrase is an enzyme that digests sucrose
how are enzymes reusable
they are reusable because they are not chemically changed by the reaction. cells typically maintain a specific enzyme concentration
what do enzymes facilitate
enzymes can facilitate synthesis or digestion reactions
