Biomolecules and Enzymes

Front

What do enzymes do?

Back

Enzymes are protein molecules that catalyze (speed up) reactions.

Front

How do enzymes speed up reactions?

Back

Enzymes speed up reactions by decreasing the activation energy required to start the reaction.

Front

What happens to the carbon, hydrogen, and oxygen atoms from sugar during digestion?

Back

They are rearranged in the body during digestion.

Front

Where does the substrate bind to the enzyme?

Back

The substrate joins the enzyme at the enzyme active site.

Front

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

Back

The active site is the region on the enzyme where the substrate binds and the reaction occurs.

Front

What are the main types of biomolecules?

Back

The main types of biomolecules are carbohydrates, proteins, lipids, and nucleic acids.

Front

What are carbohydrates primarily used for in the body?

Back

Carbohydrates are primarily used for quick energy.

Front

What is a substrate in the context of enzymes?

Back

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

Front

What is the enzyme-substrate complex?

Back

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

Front

What factors can affect enzyme activity?

Back

Factors that can affect enzyme activity include temperature, pH, and substrate concentration.
