Introduction to Enzymes

Front

What is an enzyme?

Back

An enzyme is a biological catalyst that speeds up chemical reactions in living organisms without being consumed in the process.

Front

Where do substrates bind on an enzyme?

Back

Active site.

Front

What happens to an enzyme when it denatures?

Back

The shape of the enzyme molecule is changed.

Front

What is the role of the active site in an enzyme?

Back

The active site is the region on the enzyme where substrates bind and undergo a chemical reaction.

Front

What effect does temperature have on enzyme activity?

Back

High temperatures can denature enzymes, altering their shape and reducing their activity.

Front

What is the relationship between enzymes and activation energy?

Back

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

Front

What are substrates in the context of enzymes?

Back

Substrates are the reactants that enzymes act upon during a chemical reaction.

Front

What are products in an enzymatic reaction?

Back

Products are the substances formed as a result of the enzymatic reaction.

Front

What is enzyme specificity?

Back

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

Front

What factors can affect enzyme activity?

Back

Factors include temperature, pH, substrate concentration, and the presence of inhibitors or activators.
