Enzymes and Catalyst 1

noncompetitive inhibitors

Which type of inhibitors are these: toxins, poisons, pesticides, antibiotics

enzyme

a catalyc protein

activation energy

Enzymes catalyze reactions by lowering the ___ ____

maltose

Maltase catalyzes the converstion of ____ to glucose subunits

6-8

Most enzmes have an optimal pH of

35-40 C

Most human enzymes have an optimal temperature of

cofactor

Nonprotein enzyme helpers, required for proper active site function

active site

The ___ ___ is the regioin on the enzyme where the subtrate binds

allosteric

The binding of a regulatory molecule to a protein at one site that affects the function of the protein at a diferent site

catalyst

A chemical agent that speeds up a reaction without being consumed by the reaction

noncompetitive inhibitor

Bind to another part of an enzyme, causing the enzyme to change chape and making the active site less effective

competitive inhibitor

Bind to the active site of an enzyme, competing with the subrtate

induced fit

Brings chemical groups of the active site into positions that enhance their ability to catalyze the reaction

3d shape

How does the temperature and pH effect the enzyme proteins

enzyme-catalyzed

Hydrolysis of sucrose by the enzyme sucrase is an example of an ___-____ reaciton

lactose

Lactase catalyzes the conversion of ____ to glucose and galactose subunits

activation energy

The initial energy needed to start a chemical reaction is called

subtrate

The reactant that an enzyme acts on is called the enzymes

inorganic

This type of cofactor is ____ (such as a metal in ionic form): zinc, copper, iron, etc

organic

This type of cofactor is _____ (coenzyme): vitamins, vitamin derivatives
