GS Enzymes: Friday

Front

What is an enzyme?

Back

A protein that acts as a catalyst to speed up chemical reactions in the body.

Front

What is the role of sucrase?

Back

Sucrase is an enzyme that catalyzes the hydrolysis of sucrose into glucose and fructose.

Front

What does it mean for an enzyme to denature?

Back

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

Front

What is the optimal pH for most enzymes?

Back

Most enzymes have an optimal pH around neutral (pH 7), but some, like pepsin, work best in acidic conditions.

Front

What is a catalyzed reaction?

Back

A reaction that occurs with the help of a catalyst (enzyme), resulting in a lower activation energy.

Front

What is the difference between a substrate and an enzyme?

Back

A substrate is the reactant that an enzyme acts on, while the enzyme is the catalyst that facilitates the reaction.

Front

What is the significance of enzyme specificity?

Back

Enzyme specificity refers to the ability of an enzyme to choose exact substrates from a group of similar chemical molecules.

Front

What happens to enzyme activity at extreme pH levels?

Back

Extreme pH levels can lead to denaturation of the enzyme, reducing or eliminating its activity.

Front

What is the effect of temperature on enzyme activity?

Back

Enzyme activity typically increases with temperature up to a certain point, after which it may denature.

Front

What is a reaction coordinate diagram?

Back

A graphical representation showing the energy changes during a chemical reaction, including activation energy and the effect of catalysts.
