5 Matching questions

  1. what happens in indirect method 1
  2. movement of e-* 2
  3. movement of e-* 1
  4. removal of e-* from energy source 2
  5. what happens in indirect method 2
  1. a reduction reaction acquisition of e-*and hydrogen atoms by a suitable acceptor moleule. facilitated by coenzymes ( nicotamide adenime dinucleotide called also NAD / flavin adenine dinucleotide called also FAD
  2. b - removal of e-* from energy source. this is done by oxidation reduction reaction
  3. c affinities for electrons is referred to as tge stadard reduction potential (e-o) and is measured as a voltage. the more postive the value the greater the affinity
  4. d external source(s) f energy (source of energized electrons - e-*)
  5. e electron transport system -unidirectional movemnt of ee-* thru a series of Fe-containing acceptos molecules (cytochromes) that are arranged with increasing affinities for electrons

5 Multiple choice questions

  1. 98
  2. Oxidative phosphorylation (also called ox-phos)
  3. direct coupling of an exergoinic reaction to the indergonic reaction of ATP
  4. a source of energy are organic compounds
  5. oxidation reaction - removal of e-* and hydrogen atom from energy source. facilitated by enzymes dehydrogenases ( loses hydrogen )or oxidoreduct
