GED Science Practice Test: Organic Molecules
Organic molecules are the substances that are found in, or produced by, living organisms. The feature that distinguishes an organic from inorganic molecule is that organic molecules contain carbon, whereas inorganic molecules do not. This is why people often say that life on earth is “carbon-based.” There are four major classes of organic molecules: carbohydrates, proteins, lipids and nucleic acids. These four types of organic molecules play critical roles in metabolism and other life processes.
