  1. glucose
  2. NADPred
  3. NADred
  4. ATP
  5. FADred
  1. Which is true concerning cellular respiration:
  1. It occurs within the mitochondria.
  2. The Krebs cycle is a true cycle because it begins and ends with RUBP.
  3. Glucose is split into two molecules of pyruvate.
  4. The electron transport chain converts energized electrons from NAD and FAD into ATP.
  1. Energy transformations in biological systems are accomplished by manipulating energized electrons using a series of oxidation-reduction reactions.
TRUE
FALSE
  1. Heterotrophs are able to photosynthesize.
TRUE
FALSE
  1. NADred is able to produce more ATP that FADred due to the higher energy level of the electron carried by the NADred molecule.

TRUE
FALSE
  1. The electrons stripped from the hydrogen atoms during the Krebs cycle are picked up by NADox and FADox.
TRUE
FALSE
  1. All ATP production during glycolysis and cellular respiration in eukaryotes takes place within the mitochondria.
TRUE
FALSE
  1. Photosynthesis occurs in both prokaryotes and eukaryotes.
TRUE
FALSE
