The Cell & Biomolecules Comprehensive Test Review

Front

What are proteins?

Back

Proteins are organic macromolecules composed of chains of amino acids that form the structural components of organisms.

Front

What type of transport allows small, non-polar molecules like CO2 and O2 to pass through the cell membrane?

Back

Diffusion is the process that allows small, non-polar molecules to pass through the cell membrane.

Front

Which biomolecule group includes fats, oils, and waxes?

Back

Lipids are the group of biomolecules that include fats, oils, and waxes.

Front

What is activation energy?

Back

Activation energy is the energy level that needs to increase before a reaction can occur, often represented in graphs of chemical reactions.

Front

What is endocytosis?

Back

Endocytosis is the process of engulfing or bringing large particles into the cell.

Front

What are carbohydrates?

Back

Carbohydrates are organic compounds made of carbon, hydrogen, and oxygen, and they serve as a primary energy source for living organisms.

Front

What is the function of nucleic acids?

Back

Nucleic acids, such as DNA and RNA, store and transmit genetic information.

Front

What is the role of enzymes in biological reactions?

Back

Enzymes are proteins that act as catalysts to speed up chemical reactions in the body.

Front

What is osmosis?

Back

Osmosis is the diffusion of water molecules across a selectively permeable membrane.

Front

What are lipids?

Back

Lipids are a group of biomolecules that are hydrophobic and include fats, oils, and waxes.
