background image Study Guide Exam 3 1. T or F: Membranes are SHEET LIKE STRUCTURES, two molecules thick, which  form CLOSED BOUNDARIES between different compartments.  2. What are the two main components of a cell membrane? 
3. T of F: Most cell membranes are electrically polarized, causing the inside to 
be negative, which is why membrane potential is so important in energy 
conservation, transport, and excitability.
4. T or F: Membranes are SYMMETRICAL.
5. T or F: Membranes are FLUID STRUCTURES.
6. T or F: Membranes are COVALENT ASSEMBLIES.
7. What are the functions of a protein within the membrane?
8. Protein Kinases A is an enzyme that does what?
9. Lipids in the membrane have a _____________ head and _______________ tails. 
These molecules are amphipathic, meaning they have water loving and water
fearing qualities. What is a result of them being amphipathic?
10.Lipid bilayers form spontaneously by __________________. The main driving  force in the formation of lipid bilayers is the ____________________________. 11.What type(s) of forces hold the tails together? What type(s) of forces hold the heads together? 12.What is the difference between simple diffusion and facilitated diffusion?  Active transport versus passive transport? 13.What are the three main classes of membrane receptors?
14.How can a small number of hormones binding to the extracellular surface of a
cell have a large biochemical effect inside the cell? 15.What causes the heart to contract (heart beat)? Calcium, Sodium, or  Potassium?  16.Explain the role of a sodium-calcium antiporter.
17.Where does the citric acid cycle happen in eukaryotic cells?
18.Where is the energy stored that is created in the Citric Acid Cycle?
19.How does a LOW ATP/ADP ratio affect the citric acid cycle in a cell? Low 
NADH/NAD+ ratio? 20.What are the three “important” steps in glycolysis? Are they reversible? What are the regulated steps during these steps? 21.What steps in the citric acid cycle have oxidation-reduction reactions  occurring? 22.What is the NET ATP generation in glycolysis?
23.What are the end products of the glycolysis of 1 glucose molecule?
24.What is a zymogen?
25.What are isozymes?
26.What are the four enzymes regulated in gluconeogenesis?
27.Hexokinase has 4 types of isozymes (I, II, III, and IV). What is the difference 
between the first three and the fourth? 28.Which enzyme, PFK-1, hexokinase, or Pyruvate kinase, is the most important  control site in mammalian glycolytic pathway? 29.Pyruvate Kinase is inhibited by ______ & ______? What activates pyruvate  kinase? 30.What enzymes catalyzes the reaction linking glycolysis and the citric acid  cycle? 
background image 31.What are the 5 enzymes that constitute pyruvate dehydrogenase complex?  What does each catalyze? 32.What coenzymes are required by pyruvate dehydrogenase complex?
33.What is the net equation for the citric acid cycle?
34.How is it possible that there is no O
2  exchange in the citric acid cycle, yet it is  considered aerobic respiration? 35.Why is succinate dehydrogenase unique when compared to all the other  enzymes in the citric acid cycle? ** Know how to calculate delta G values of reactions.  ** take extra time on citric acid cycle and glycolysis! Know the pathways
