    Concept 9.1 Metabolic pathways that release energy  are called catabolic pathways - fermentation and cellular respiration _____________ : partial degradation of  sugars that occurs w/out the help of O 2 ________ : O 2  is consumed as a reactant  along w/ the sugar - more efficient

    Concept 9.1 Cellular respiration occurs in the  _______________  Organic + O 2    Carbon + H 2 O + Energy compounds    dioxide C 6 H 12 O 6  + 6O 2    6CO 2  + 6H 2 O + Energy 1 glucose = -686 kcals

    Concept 9.1 ATP is the central molecule responsible  for energy used by the cell The cell uses enzymes to transfer  phosphate groups from ATP to other  compounds (making them  _________________ ) ATP   ADP + phosphate

    Concept 9.1 Redox reactions release energy when  electrons move closer to electronegative  atoms - the relocation of electrons releases the  energy stored in food molecules, and this  energy is used to synthesize ATP

    Concept 9.1 There is a transfer of one or more e- from  one reactant to another; the electron  transfers are called oxidation-reduction  reactions or redox rxns.  - the loss of e- from one substance is  called  ____________ - the addition of e- to another substance  is called  ___________

    Concept 9.1 Electrons “fall” from organic molecules to  oxygen during cellular respiration ____________________________________ - by oxidizing glucose, cellular respiration  takes energy out of storage and makes it  available for ATP synthesis - carbohydrates and fats are reservoirs of  electrons associated w/ hydrogen
Background image of page 8
  Concept 9.1 The “fall” of electrons during respiration is  stepwise, via NAD   +  and an electron transport  chain Glucose is broken down over a series of steps  that are each catalyzed by a specific enzyme Hydrogen atoms are stripped from the glucose  and usually passed to NAD + . - NAD
