Biology Unit 1


Biology The study of living things.
Abiotic Nonliving factors in an environment.
Biotic Living factors in an environment.
Independent Variable What is being tested; the variable that is manipulated.
Dependent Variable The responding variable; responds to the changes made to the independent
Contant Stays the same throughout the experiment.
Control Group The group that acts as the standard for comparison. The “normal” group.
pH Measurement of how acidic of basic a solution is.
Acidic Has a pH below 7
Basic Has a pH above 7
Neutral Has a pH of 7 (pure water)
Organic Molecules Have the element Carbon in them.
Inorganic Molecules Do not have the element Carbon in them.
Carbohydrates Also known as saccharides. Main source of energy (short term). Subunits: monosaccharides.
Cellulose Complex carbohydrate found in within the cell walls of plants. Used for structural purposes.
Glycogen Carbohydrate found in animal cell muscles and liver. Used for energy storage. (short term)
Lipds Used for long term energy storage, some structure, insulation. Found in cell membrane. No real subunits, but made of glycerol and fatty acids.
Proteins Used for everything. Subunit: Amino Acids.
Metabolism The sum of all chemical reactions in an organism.
Catabolism Breaking down of molecules.
Anabolism Building up of molecules.

Catalyst Another name for enzyme.
Substrate Molecule that enzymes work on
Products What the enzyme helps produce in the reaction
Active Site Part of the enzyme the substrate molecule fits in to.
Denature Changing the shape of a protein (enzyme), mostly by temperature or pH.
