What is cristae?  Describe the three types of phosphorylation by cells.  Differentiate substrate level phosphorylation from oxidative phosphorylation.  Compare combustion from aerobic cellular respiration.  What are the stages of aerobic cellular respiration? Study Fig. 9.6, p. 166.  About Glycolysis  What is its other name?  It occurs in what part of the cell.  It consists of how many steps?  After the completion of this process,

  • what happens to glucose?
  • how many net ATP are produced from one molecule glucose? By what type of phosphorylation?
  • how many NADH are produced from one molecule glucose?  About the Transition step  What happens to pyruvic acid?  How many CO2 are produced from two molecules pyruvic acid?  How many NADH are produced from two molecules pyruvic acid?  About Kreb’s cycle  What is its other name?  It occurs in what part in prokaryotic cell? in eukaryotic cell?  What is the substance that enters the cycle?  It consists of how many steps?  After the completion of this process, for two molecules of acetylCoA,
  • how many ATP are produced? Name the type of phosphorylation.
  • how many NADH are produced?
  • how many FADH2 are produced?
  • CO2 are produced?  About Electron Transport System (ETS)  Which complex received electrons from NADH (from glycolysis, transition stage and TCA)?  Which complex received electrons from FADH2 (from TCA)  As the electrons are passed from one acceptor to another in the ETS, what is released?  What is the function of the energy that is released as the electrons move down the chain?  What happens to the H+ concentration outside the membrane? inside the membrane?  What is the final electron acceptor?  What is protonmotive force?
