enzyme

- the active site has a rigid shape - only substrates with the matching shape can fit - the substrate is a key that fits the lock of the active site

non protein part of the enzyme

mention three types of enviromental factor that affect enzyme reactions

structure different than substrate

Enzymes increase reaction rates by ............... the Activation energy

- the active site is flexible, not rigid - the shapes of the enzyme, active site, and substrate adjust to maximumize the fit, which improves catalysis - there is a greater range of substrate specificity

The enzyme molecules begins to lose its shape and activity, and it’s said to be

The area on the enzyme where the substrate or substrates attach to is called

vitamins are example of

inhibitor that bind to the substrate

the substance at the beginning of the process, on which an enzyme begins it’s action

All chemical reactions require some amount of energy to get them started.

part of the co factor that contain of small, inorganic molecules

part of the cofactor that contain large organic molecule

protein part of the enzyme

As temperature rises, the enzymes and substrate molecules move
