STAAR Review: Biomolecules and Cells Structure

Front

What are biomolecules?

Back

Biomolecules are organic molecules that are essential for life, including proteins, lipids, carbohydrates, and nucleic acids.

Front

What are the four main types of biomolecules?

Back

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

Front

What is the primary function of proteins?

Back

Proteins serve various functions including catalyzing biochemical reactions (enzymes), providing structure, and facilitating communication in cells.

Front

What are lipids and their functions?

Back

Lipids are biomolecules that include fats, oils, and waxes. They function in energy storage, insulation, and making up cell membranes.

Front

What is the role of carbohydrates in living organisms?

Back

Carbohydrates provide energy and serve as structural components in cells.

Front

What are nucleic acids and their primary function?

Back

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

Front

What is the structure of a cell membrane?

Back

The cell membrane is composed of a phospholipid bilayer with embedded proteins, which controls the movement of substances in and out of the cell.

Front

What is the function of the Golgi apparatus?

Back

The Golgi apparatus modifies, sorts, and packages proteins and lipids for storage or transport out of the cell.

Front

What is the role of ribosomes in cells?

Back

Ribosomes are the sites of protein synthesis, where amino acids are assembled into proteins.

Front

What is the function of vacuoles in plant cells?

Back

Vacuoles store nutrients, waste products, and help maintain turgor pressure in plant cells.
