Chemistry of Life and Cells Ch. 2 and 7

Macromolecules Lipids Carbohydrates Function: store energy, part of biological membranes and waterproof coverings Structure: Glycerol—Fatty acid Carbohydrates Function: energy and structural proposes Structure: monosaccharides—polysaccahrides

Nucleic Acids Function: store and transmit hereditary information Protein Function: control rate of reactions and regulate cell processes, impt. In cell structure, fight disease, transportation Structure: amino acid---protein

Enzymes http://www.youtube.com/watch?v=XTUm-75-PL4 Lower activation energy Effected by pH and temperature

Water’s Special Properties http://www.youtube.com/watch?v=QgWGrnnda0A Cohesion vs. adhesion Moderate temperature Expansion upon freezing Universal solvent

Cell Theory http://www.youtube.com/watch?v=dgHN145_dj0 Robert Hooke: looked at cork under a microscope, saw chambers, called them “cells” Anton van Leeuwenhoek: looked at pond water under a single-lens microscope

Matthias Schleiden: all plants are made of cells Theodor Schwann: all animal are made of cells Rudolf Virchow: cells come from pre-existing cells

Cell theory: All living things are made of cells Cells are the basic unit of structure and function in living things New cells are produced from existing cells
