ENZYME CHALLENGE

A substance which speeds up a reaction

• Activation energy

• Enzyme

• Substrate

• Delta energy

Model where the shape of the active site alters slightly.

• Lock and Key

• Induced-Fit

• Enzyme-Substrate Complex

• Enzyme-Product Complex

Increasing this denatures an enzyme.

• pH

• Enzyme concentration

• Inhibitor

• Temperature

This enzyme functions best at pH 8.

• Trypsin

• Pepsin

• Peptidase

• Sucrase

Vitamin derived molecules which help enzymes.

• Inorganic ions

• Coenzyme

• Metal ions

• Cofactor

The place where the substrate binds at.

• Surface area

• Pocket

• Active site

• Allosteric site

The "lock and key hypothesis" attempts to explain the mechanism of

• vacuole formation

• pinocytosis

• sharing of electrons

• enzyme specificity

An enzyme that hydrolyzes protein will not act upon starch. This fact is an indication that enzymes are

• Hydrolytic

• Specific

• Catalytic

• Synthetic

Enzymes influence chemical reactions in living systems by

• providing the substrate required for the reaction to occur

• affecting the rate at which reactions occur

• absorbing water released when polymers are formed

• combining with excess hydrogen to form gaseous wastes

At high temperatures, the rate of enzyme action decreases because the increased heat

• changes the pH of the system

• alters the active site of the enzyme

• neutralizes the acids and bases in the system

• increases the concentration of the enzyme
