Enzymes

Front

What is an enzyme?

Back

An enzyme is a biological catalyst that speeds up chemical reactions in living organisms.

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

How do enzymes affect activation energy?

Back

Enzymes lower the activation energy required for a chemical reaction to occur.

Front

What are products in a chemical reaction?

Back

Products are the substances that are formed as a result of a chemical reaction.

Front

What is the enzyme-substrate complex?

Back

The enzyme-substrate complex is the temporary complex formed when an enzyme binds to its substrate.

Front

What role do enzymes play in metabolic pathways?

Back

Enzymes facilitate and regulate the biochemical reactions that occur in metabolic pathways.

Front

What factors can affect enzyme activity?

Back

Factors that can affect enzyme activity include temperature, pH, substrate concentration, and the presence of inhibitors or activators.

Front

What is a substrate in the context of enzyme activity?

Back

A substrate is the reactant molecule that an enzyme acts upon during a chemical reaction.

Front

What is enzyme specificity?

Back

Enzyme specificity refers to the ability of an enzyme to select and catalyze a specific substrate or group of substrates.

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 on the enzyme, altering its function.
