A&P: Chemistry Part I

The study of living materials requires an understanding of chemistry. Which of the following is an example of this?

• Understanding how enzymes catalyze reactions in cells

• Learning about the history of ancient civilizations

• Studying the structure of a poem

• Analyzing the causes of World War II

The relationships among matter, atoms, and molecules can be described as:

• Matter is made up of atoms, which combine to form molecules.

• Atoms are made up of molecules, which combine to form matter.

• Molecules are made up of matter, which combine to form atoms.

• Matter is made up of molecules, which combine to form atoms.

The general structure of an atom can be described as:

• A nucleus containing protons and neutrons, surrounded by electrons

• A solid sphere with no internal structure

• A core of electrons surrounded by protons and neutrons

• A shell of neutrons with protons and electrons inside

Atomic structure determines how atoms interact by:

• Determining the arrangement of electrons and their ability to form bonds

• Controlling the size of the nucleus only

• Affecting only the mass of the atom

• Having no effect on atomic interactions

Atomic structure determines how atoms interact by:

• Determining the arrangement of electrons, which affects bonding and interactions

• Controlling the number of protons, which affects color

• Setting the atomic mass, which determines reactivity

• Defining the nucleus size, which affects melting point
