During your explorations of previous lessons, what four types of molecules did you find that make up the structural components of a cell? - Carbohydrates / Lipids / Nucleic Acids / Proteins Shown to the right are diagrams of each of the components you identified in your exploration. They, in turn, are made up of smaller pieces called atoms, connected by things called bonds. Identify in the graphic below which pieces you think are atoms and which you think are bonds. - 1. Bond 2. Atom Atoms and bonds are often represented in chemical structures by balls and sticks, but like organelles, are more complex than they are often represented. Later, you'll learn about bonds. For now, you'll explore what an atom is. - An atom is the smallest unit of ordinary matter that forms a chemical element. It is made up of protons, neutrons, and electrons.
