1. 1st law of thermodynamics: The principle of conservation of energy. Energy can be transferred and transformed, but it cannot be created or destroyed. 2. 2nd law of thermodynamics: The principle whereby every energy transfer or transformation increases the entropy of the universe. Ordered forms of energy are at least partly converted to heat, and in spontaneous reactions, the free energy of the system also decreases. 3. absorption spectrum: The range of a pigment's ability to absorb various wavelengths of light. 4. Acetyl CoA: The entry compound for the Krebs cycle in cellular respiration; formed from a fragment of pyruvate attached to a coenzyme. 5. acid precipitation: Rain, snow, or fog that is more acidic than pH 5.6. 6. acid: a substance that increases the hydrogen ion concentration of a solution 7. actin: A globular protein that links into chains, two of which twist helically about each other, forming microfilaments in muscle and other contractile elements in cells. 8.
