Enzymes

Front

What are enzymes primarily composed of?

Back

Proteins

Front

What is the term for the molecule that an enzyme acts upon?

Back

Substrate

Front

What is produced after an enzyme catalyzes a reaction with its substrate?

Back

A product

Front

What is the name of the complex formed when an enzyme binds to its substrate?

Back

Enzyme-substrate complex

Front

What role do enzymes play in biochemical reactions?

Back

They act as catalysts to speed up reactions.

Front

What factors can affect enzyme activity?

Back

Temperature, pH, substrate concentration, and enzyme concentration.

Front

What is the effect of temperature on enzyme activity?

Back

Enzymes typically have an optimal temperature range; too high or too low can denature the enzyme or reduce activity.

Front

How does pH affect enzyme activity?

Back

Each enzyme has an optimal pH range; deviations can lead to decreased activity or denaturation.

Front

What is enzyme specificity?

Back

The ability of an enzyme to choose exact substrates from a group of similar chemical molecules.

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 site, altering enzyme function.
