Flashcard on Atomic Structure

Front

What is the role of enzymes in chemical reactions?

Back

Enzymes act as catalysts that speed up chemical reactions by lowering the activation energy required for the reaction to occur.

Front

What is a control group in an experiment?

Back

A control group is a group in an experiment that does not receive the treatment or intervention being tested, allowing for comparison with the experimental group.

Front

What is the significance of activation energy in chemical reactions?

Back

Activation energy is the minimum energy required for a chemical reaction to occur. Enzymes lower this energy, making reactions happen more easily.

Front

What distinguishes lipids from carbohydrates, proteins, and nucleic acids?

Back

Lipids are characterized by long chains of carbon and hydrogen atoms, which are not present in carbohydrates, proteins, or nucleic acids.

Front

What is the relationship between patterns and cause and effect in biology?

Back

Patterns in biological phenomena often indicate underlying cause and effect relationships, helping to explain why certain events occur.

Front

How do enzymes affect the free energy of reactants and products?

Back

Enzymes do not change the free energy of the reactants or products; they only lower the activation energy needed for the reaction.

Front

What is the difference between an experimental group and a control group?

Back

The experimental group receives the treatment being tested, while the control group does not, serving as a baseline for comparison.

Front

What is carbonic anhydrase and its function?

Back

Carbonic anhydrase is an enzyme that catalyzes the conversion of carbon dioxide and water into carbonic acid, facilitating gas exchange in the body.

Front

What are crosscutting concepts in biology?

Back

Crosscutting concepts are ideas that apply across different areas of science, helping to connect and unify various disciplines.

Front

What is the importance of understanding molecular structures in biology?

Back

Understanding molecular structures helps explain the functions of biomolecules and their roles in biological processes.
