GS Enzymes: Friday

Front

What is activation energy?

Back

The minimum amount of energy required for a chemical reaction to occur.

Front

What role do enzymes play in relation to activation energy?

Back

Enzymes lower the activation energy of a reaction, making it easier for the reaction to occur.

Front

What is denaturation in enzymes?

Back

Denaturation is the process where an enzyme loses its functional shape due to external factors like temperature or pH.

Front

Which enzyme does not denature with any pH?

Back

Sucrose.

Front

What is the function of lipase?

Back

Lipase is an enzyme that breaks down fats into fatty acids and glycerol.

Front

What is the optimal pH for most enzymes?

Back

Most enzymes have an optimal pH around neutral (pH 7), but some function best in acidic or basic conditions.

Front

What is a substrate in enzymatic reactions?

Back

A substrate is the reactant molecule upon which an enzyme acts.

Front

What is the active site of an enzyme?

Back

The active site is the specific region of an enzyme where the substrate binds and the reaction occurs.

Front

What is the difference between competitive and non-competitive inhibition?

Back

Competitive inhibition occurs when an inhibitor competes with the substrate for the active site, while non-competitive inhibition occurs when an inhibitor binds to a different part of the enzyme.

Front

What is an enzyme-catalyzed reaction?

Back

An enzyme-catalyzed reaction is a chemical reaction that is accelerated by the presence of an enzyme.
