Enzymes

Front

What do enzymes speed up in chemical reactions?

Back

Enzymes speed up reaction rates by lowering the activation energy.

Front

Which of the following is an enzyme?

Back

Amylase is an enzyme.

Front

What is the optimal temperature for enzyme activity based on a typical graph?

Back

The optimal temperature for enzyme activity is often around 30°C.

Front

What is the primary function of an enzyme?

Back

The primary function of an enzyme is to speed up chemical reactions.

Front

What is the active site of an enzyme?

Back

The active site is the region on the enzyme where substrates bind and reactions occur.

Front

What is a substrate in the context of enzymes?

Back

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

Front

What happens to enzymes at high temperatures?

Back

High temperatures can denature enzymes, causing them to lose their functional shape.

Front

What is 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 role do cofactors play in enzyme activity?

Back

Cofactors are non-protein molecules that assist enzymes in catalyzing reactions.

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.
