· BIOLOGY A: Scientific Method, Biomolecules
Updated: 10.04.09
Ca Standard 1h: Most macromolecules (polysaccharides, nucleic acids, proteins, lipids) in cells and organisms are synthesized from a small collection of simple precursors.
Ca Standard 1b: Enzymes are proteins that catalyze biochemical reactions without altering the reaction equilibrium and the activities of enzymes depend on temperature, ionic conditions, and the pH of the surroundings.
