Enzymes

Front

What are enzymes?

Back

Enzymes are biological catalysts that speed up chemical reactions in living organisms without being consumed in the process.

Front

What is the active site of an enzyme?

Back

The active site is the specific region of an enzyme where substrate molecules bind and undergo a chemical reaction.

Front

What factors affect enzyme activity?

Back

Enzyme activity can be affected by temperature, pH, substrate concentration, and the presence of inhibitors or activators.

Front

What is the optimum pH for most enzymes?

Back

Most enzymes have an optimum pH around neutral (pH 7), but some work best in acidic (pH < 7) or basic (pH > 7) conditions.

Front

What happens to enzymes at high temperatures?

Back

High temperatures can denature enzymes, altering their structure and rendering them inactive.

Front

What is substrate concentration?

Back

Substrate concentration refers to the amount of substrate available for the enzyme to catalyze a reaction.

Front

What is enzyme denaturation?

Back

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

Front

What is the role of amylase?

Back

Amylase is an enzyme that catalyzes the breakdown of starch into sugars.

Front

What is a competitive inhibitor?

Back

A competitive inhibitor is a substance that competes with the substrate for binding to the active site of an enzyme.

Front

What is a non-competitive inhibitor?

Back

A non-competitive inhibitor binds to an enzyme at a site other than the active site, reducing the enzyme's activity regardless of substrate concentration.
