Biochemistry Revision (1) Wednesday 7-1-2009 Q1/Compare b/w neural and humeral communicate? Neural communication humoral communication 1-single target cells 2-signal amplitude can be well regulated 3- very rapid 4-transient 1-less target directed 2-signal amplitude not well regulated 3- slower 4-persists longer When yeast cells communicate One yeast cell type produce one main effectors acting on the other yeast cell and when they interact they form shmooth “special form” Eg for communication b/w 2 cells If you stimulate electrically and it is transit so transit is the key word for signaling.The signal transduction should not be forever. Q2/which classes of different hormones is exist (8 material classes with exam Hormone class Example Hormone class Example Proteins Interleukines Growth factors Interferons Fatty acid-derivatives Prostaglandines Leukotrienes Peptides Insulin Glucagon Biogenic amines Acetylcholine Steroids Glucocorticoids Sex hormones Mineralocorticoids Amino acid-derivatives Adrenaline Glutamate Thyroxine Retinoids Gases NO What are the other possible classification ???? glandular – aglandular – hydrophilic – hydrophobic Q3/Example for glandulare and aglandulare hormones (2) examples of hydrophilic/hydrophobic hormones (2) 1
