Unit 1: Macromolecules & Experimental Design

Front

What is a macromolecule?

Back

A macromolecule is a large molecule composed of thousands of atoms, typically organized into complex structures. Examples include proteins, nucleic acids, carbohydrates, and lipids.

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 monomer of carbohydrates?

Back

The monomer of carbohydrates is a monosaccharide, such as glucose.

Front

What is a polymer?

Back

A polymer is a large molecule made up of repeating subunits called monomers.

Front

What is the relationship between starch and glucose?

Back

Starch is a polymer made of glucose monomers.

Front

What are nucleic acids made of?

Back

Nucleic acids are made of nucleotides, which consist of a sugar, a phosphate group, and a nitrogenous base.

Front

What is the function of proteins?

Back

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

Front

What is the role of lipids in biological systems?

Back

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

Front

What is an independent variable in an experiment?

Back

The independent variable is the factor that is manipulated or changed in an experiment to test its effects.

Front

What is a dependent variable in an experiment?

Back

The dependent variable is the factor that is measured or observed in response to changes in the independent variable.
