  • The purpose of cellular respiration in a eukaryotic cell is to
    break down carbohydrates to provide ATP for the cell.
  • The reactants of Cellular Repiration
    glucose and oxygen
  • The process by which glucose is split to produce ATP and lactic acid or ethanol.
    Fermentation
  • Which molecule enters the Krebs cycle
    Acetyle CoA
  • The four stages of cellular respiration
    glycolysis, link, krebs, oxidative phosphorylation
  • NADH is the _____ form of NAD+
    reduced
  • Which process is found in both aerobic and anaerobic metabolism
    glycolysis
  • Which phase produced water
    Oxidative Phosphorylation
  • A term for metabolic pathways that release stored energy by breaking down complex molecules is
    catabolic pathways
  • The amount of ATP produced in Glycolysis
    2 ATP
  • Besides ATP what else is produced during Krebs
    Carbon dioxide, NADH and FADH2
  • What is the final electron acceptor for cellular respiration
    oxygen
  • At the end of cellular respiration, oxygen is (oxidized/reduced)
    reduced
  • This term refers to the production of ATP without oxygen being present
    anaerobic
  • What is the equation for cellular respiration
    Glucose + Oxygen-----> Carbon dioxide + water + energy
  • Besides ATP what else is produced during glycolysis
    NADH and Pyruvate
  • Which macromolecule produces the most ATP per gram?
    fats
  • The use of oxygen is ____________ respiration
    aerobic
  • The process by which glucose is split into pyruvate producing ATP and NADH.
    Glycolysis
  • The products of cellular respiration
    Carbon dioxide, water, ATP
  • Two different species of bacteria are examined. Scientists find that species X always produces CO2 and H2O during cellular respiration. Species Y always produces ethyl alcohol and CO2. Which one is anaerobic?
    species Y
  • After strenuous exercise, a muscle cell would contain decreased amounts of _______ and increased amounts of ________ _______
    oxygen, lactic acid
