PPT-Excitable cells and their biochemistry

David Taylor dcmtlivacuk httpwwwlivacukdcmt When you have worked through this you should be able to Remember the function of the cell membrane and definition of membrane potential . Over the past decade an ever growing arsenal of techniques has helped researchers dissect the innermost secrets of the cell and develop new ways to detect and attack disease These techniques also have been used to produce vast amounts of once rare d x Muscle cells and x nerve cells neurons are excitable The color photo courtesy of Julie H Sandell and Richard H Masland is of a single inter neuron in the retina of a rabbit The cell has been injected with a f luorescent dye to reveal all its branc Here however we confine atten tion to cells that perform their functions by undergoing a macroscopic transition in response to an external stimulus Mostly the transitions are reversible although in some cells they occur but once Examples of repetit Dr. .

BEAR BEHAVIOR, BIOCHEMISTRY, AND HIBERNATION * Nelson et al. 285 In winter, urea turnover is greatly reduced be- cause of an increase in effectiveness of protein anabolism. Amino acids enter protein a - cium channels (VGCCs; also known as Ca V s) respond to a depolarization of membrane potential by allowing Ca 2+ entry. This response provides Ca 2+ for many processes, including neurotransmitter Basic reference: Keener and . Sneyd. , Mathematical Physiology. So far we concentrated on Na. +. (and K. +. ), as those are the ions that are most important for the control of cell volume and the membrane potential.. Aron. . Wolinetz. Who am I?. PhD student at the CUNY Graduate Center.

Biochemistry. is the application of chemistry to study biological processes at the cellular and molecular level.. Biochemistry is also concerned with the study of the structure and function of cellular components, such as proteins, carbohydrates and lipids.. 1. What is Biochemistry?. Biochemistry = chemistry of life. . Biochemists use physical and chemical principles to explain biology at the molecular level.. Basic principles of biochemistry are common to all living organism.
