This website volition hold upward a resources for yous every 2nd yous embark on ii years of higher flat IB Biology. Here yous tin detect useful links, virtually degree documents, in addition to a fairly-well updated schedule of what nosotros are doing inward class. Come hither offset if yous missy class, lose a hand-out, or simply can't scream upward what is due. Feel gratuitous to email me at mkenny@pps.net if yous accept whatsoever questions at all. I'm non connected to the spider web 24-7 similar many people these days, but I produce endeavour to response inside 12-24 hours.
A. METABOLISM - all biochemical reactions that transform matter, loose energy in addition to information 3 basic stages: 1. Uptake of substances (for example, across the plasma membrane) 2. Transformation of substances ( anabolism or catabolism - explained a fleck later!) 3. Release of substances (for example, the elimination of metabolic wastes across the plasma membrane) - at that topographic point are lots of interrelated reactions, thus it is hard to study Image from http://www.expasy.org/biomap/images/pathway-1b.png Metabolic pathway - the order inwards which reactions affecting a starting pith occur. A metabolic pathway may endure linear or circular in addition to the product (end substance) of i pathway may endure the reactant (starting substance) of another. Often reactions inwards a pathway are reversible . All pathways conduct hold the next participants: 1. Substrates/reactants (kiindulóanyagok) - substances that l...
