5 Matching Questions

  1. Oxidation
  2. Autotrophic
  3. FMN (flavin mononuclotide)
  4. FAD
  5. Glycolytic Pathway
  1. a flavin adenine dinucleotide
  2. b - loss of an electron
    - NAD⁺, FAD, NADP⁺ are referred to as oxidizing agents because they cause other molecules to lose electrons and undergo oxidation (while they're reduced NADH, FADH₂, NADPH)
  3. c - green plants
    - convert sunlight into bond energy stored in the bonds of organic compounds (glucose) in the anabolic process of photosythesis
    - don't need an exogenous supply of organic compounds
  4. d - fructose 1,6-diphosphate is split into dihydroxyacetone and glyceraldehyde 3-phosphate (PGAL)
    - dihydroxyacetone is isomerized into PGAL
    - two molecules of PGAL is formed per molecule of glucose
    - 1 glucose = 2 pyruvate
    - net production of 2 ATP/mole of glucose (4 generated, 2 used up)
  5. e - first molecule of the ETC
    - reduced when it accepts electrons from NADH, therefore oxidizing NADH to NAD⁺

5 Multiple Choice Questions

  1. - ATP is produced when high energy potential electrons are transferred from NADH and FADH₂ to oxygen by a series of carrier molecules located in the inner mitochondrial membrane
    - as the electrons are transferred from carrier to carrier, free energy is released
    - later this energy is used to form ATP
  2. - NAD⁺, FAD, NADP⁺
    - transport the high energy electrons of the hydrogen atoms to a series of carrier moelcules on the inner mitochondrial membrane (electron transport chain)
  3. - adenosine monophosphate
    - PPi: phyrophosphate
    - ATP --> AMP + PPi + 7 kcal/mole
  4. - occurs in certain fungi and bacteria and in human muscle cells during strenuous activity
    - happens when oxygen supply to muscle cells lags behind the rate of glucose catabolism
    - pyruvate generated is reduced to lactic acid, which can lower blood pH if accumulated, eventually becomes muscle fatigue
    - oxygen debt: the amount of oxygen needed to oxidize lactic acid back to pyruvate and enters cellular respiration
  5. - gain of electrons

5 True/False Questions

  1. Net reaction of photosynthesis6CO₂ + 2H₂O + energy --> C₆H₁₂O₆ + 6O₂

          

  2. Proton Gradient- the body degrades amino acids only when there isn't enough carbs available
    - most amino acids undergo a transamination reaction where they lose an amino group to form an alpha-keto acid
    - carbon atoms of most amino acids are converted into acetyl CoA, pyruvate or one of the intermediates of the citric acid cycle

          

  3. NAD⁺nicotinamide adenine dinuclotide

          

  4. Alternate Energy Sources- molecular carriers used by the cell to shuttle energy between reactions
    - ATP, NAD⁺, FAD

          

  5. Net Reaction for Glycolysis6CO₂ + 2H₂O + energy --> C₆H₁₂O₆ + 6O₂
