Front

What type of macromolecule makes up the cell membrane?

Back

Lipids are the primary macromolecules that compose the cell membrane, providing structure and function.

Front

What are polysaccharides?

Back

Polysaccharides are complex carbohydrates formed by long chains of monosaccharides, such as starch and glycogen.

Front

What is a carbohydrate?

Back

Carbohydrates are organic compounds made of carbon, hydrogen, and oxygen, typically in a ratio of 1:2:1, and serve as a primary energy source.

Front

What are triglycerides composed of?

Back

Triglycerides are made up of one glycerol molecule and three fatty acids.

Front

What is starch?

Back

Starch is a polysaccharide that serves as a storage form of energy in plants, composed of many glucose units.

Front

What are the four main types of macromolecules?

Back

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

Front

What is the function of lipids in biological systems?

Back

Lipids serve as energy storage, structural components of cell membranes, and signaling molecules.

Front

What are amino acids?

Back

Amino acids are the building blocks of proteins, consisting of an amino group, a carboxyl group, and a unique side chain.

Front

What is the role of proteins in the body?

Back

Proteins perform a variety of functions including catalyzing biochemical reactions (enzymes), providing structure, and facilitating communication.

Front

What are nucleic acids?

Back

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