  4. Both carbohydrates and lipids are broken down into Acetyl-CoA for further processing. What pathway does Acetyl-CoA go to next?: Citric Acid Cycle (CAC)
  1. What is the "ETC" and what happens there?: Electron transport chain. NADHis converted into ATP at the ETC.
  2. What is the sign (+ or -) of ” G for the breakdown of ATP to ADP? Why is the sign important?: (-). A negative means spontaneous, or favorable, and is able topower other processes.
  3. What are the two phases of glycolysis? How many reactions in each?: The preparatory phase and payoff phase. Five reactions in each.
  4. How many ATPs are invested in glycolysis?: 2
  5. What is the net number of ATP gained from glycolysis?: 2 (2 invested, 4gained, for a net of 2)

C) Reaction 3 D) Fructose-6-phosphate

  1. How many steps are found in the CAC?: 8
  2. How much ATP is produced per NADH molecule after oxidative phospho-rylation? Per FADH2?: NADH- 2.5 per molecule. FADH2 - 1.5 per molecule
  1. How many CO2 are lost per each turn of the CAC?: 2 molecules of CO2 arelost.
  2. How many of the steps in the CAC are equilibrium reactions?: 5
  3. What reaction is catalyzed by the PDH?: pyruvate to acetyl-CoA
  4. The ²-oxidation pathway is the degradation pathway for fatty acids. A. Where, in the cell, does the ²-oxidation pathway occur? B. How many steps arein the ²-oxidation pathway?: A. In the mitochondria. B. Four reaction steps.
  5. How many FADH2 and NADH molecules are produced per round of ²-oxida-tion?: One of each FADH2 and NADH.
  6. Can ²o- xidation occur with odd-numbered fatty acids? Can ²o- xidation occur with fatty chains containing double bonds? Explain your answer in at least three complete sentences.: Yes to both types of chains. The ²-oxidation process occurs with both
  1. how can molecules such as pyruvate, ADP, and ATP move across the membrane: through integral proteins called transporters.
  2. what is ATP used for in the cytosol: ATP is used to power reactions that are notfavorable. In other words, ATP can be broken down enzymatically to ADP, releasing energy to perform work
  3. why is FADH2 different than NADH: The structure of FADH2 is slightly different from that of NADH, which permits it to interact with different proteins, an advantage to complex systems.
  4. biomolecules that store energy: carbohydrates, lipids, proteins
  5. example of common intermediate in metabolic reaction: acetyl coA
  6. True or False: The ” G value for a particular reaction is +52kJ/mol. This value indicates the reaction is NOT spontaneous.: true
  1. True or false: A biochemical metabolic pathway is a single reaction thatconverts starting material into products.: false
  2. True or false: Two ATP molecules are used in the energy-investing stage of glycolysis.: true
  3. True or False: The citric acid cycle occurs in the absence of oxygen.: false
  4. True or false: The ²-oxidation pathway only degrades odd-numbered fattyacids.: false
  5. In total, how many net ATP and NADH are produced (or required) in theglucose to pyruvate steps in glycolysis?: 2 ATP and 2 NADH produced
  6. In converting glucose to pyruvate, how many ATP or NADH are produced(or required) in the phosphoenolpyruvate to pyruvate step in glycolysis?: 2 ATP produced
  7. What is the primary reactant of glycolysis?: glucose
  8. In glycolysis, when glucose enters a cell, it is immediately phosphorylated to form glucose-6-phosphate. The phosphate donor in this reaction is ATP, andthe enzyme is .: hexokinase
  9. In the sixth reaction of glycolysis, ATP is formed by the direct transfer of a phosphate group from a metabolite to ADP. This process is referred toas:: substrate-

D. UTP

E. None of the above: E

49. The enzymes and coenzymes of the citric acid cycle are all present in the .: mitochondria 50. Cellular respiration is the process of cells taking in and producing to generate energy. A. Glucose; NADH B. FAD; FADH C. CO2; ATP D. NAD+; NADH E. O2; CO2: E

  1. How many phases are in the complete degradation of glucose via cellular respiration?: 3
  2. The PDH complex has three enzymes, which are referred to as:: E1 E2 E
  3. What coenzyme(s) is (are) necessary for ²-oxidation?: NAD+ and FAD
  4. The sequential process for oxidizing fatty acids to acetyl-CoA is oftencalled:: B- spiral
  1. (Short answer) At the end of the Preparatory Phase of glycolysis, there are two products. A) What are the two products? B) What happens to each product?: In step 5 of glycolysis, glucose (six-carbon) is converted to GAP and DHAP (both 3-carbons). GAP goes on in the glycolysis pathway. The other, DHAP,cannot go on through glycolysis directly; it is converted to GAP by triose phosphateisomerase. 56. (Fill in the blank) Use the following word bank to fill in the appropriate blanks. Not all words will be used; words can be used more than once.

Word bank: one, two, three, four, five, six,

Glucose contains (A) carbon atoms. The preparatory phase of gly- colysis consists of (B) steps. The oxidation of a glucose mole- cule utilizes two ATP molecules. Later, the two (C) -carbon products of glycolysis produce (D) ATP by direct phosphorylation, which gives a net yield of two ATP. In addition, (E) NADH are produced inglycolysis.: A) six B) five C) three

57. Short Essay Describe the three phases of the complete oxidative catabolism of glucose to form CO and H2O. Be sure to give the important pathway in each phase and the energy molecules produced in each. (Answer in at least 6 sentences giving specific details, such as molecules and names of pathways.): Answer: First phase: Glucose metabolism begins withglycolysis which degrades the molecule into two molecules of pyruvate and also produces 2 ATP and 2 NADH molecules. The pyruvate is converted to acetyl-CoA. Second Phase: the acetyl-CoA groups are shuttled through the citric acid cycle to generate GTP, NADH, FADH2 molecules along with the release of CO2. Third Phase:the NADH and FADH2 coenzymes are themselves oxidized in the mitochondria to yield ATP by a process called oxidative phosphorylation.
