Biology The Chemical Basis of Life

The Chemical Basis of Life

• All objects, whether living or nonliving, are made of matter. Matter is anything that has mass and occupies space. In the past, the structure and transformation of matter was mainly of interest to chemists, not biologists.

• However, the boundary between chemistry and biology has been blurred over the past few decades, as advances in biology have come about through careful study of the molecular and atomic nature of life and living systems. In other words, we have to understand some basic chemistry in order to fully understand important ideas in biology.

• We'll learn about the major and trace elements of life and the states in which they can exist. We'll also explore basic ideas about how atoms connect and how molecules interact and react.
