- Question 1: ATP synthases contains 3 copies of each of the large subunits (called α and β in the E. coli enzyme). The number of c subunits can vary among different ATP synthases, ranging from 8 to 17. Part a: Briefly explain how this variation in the number of c subunits would affect the energetics of ATP synthesis. For a fixed value of the protonmotive force, how much energy can the gradient provide to drive one revolution of the ATP synthase, in a synthase with 8 c- subunits versus a synthase with 17 c-subunits?Question:- 33) Glucose-6-phosphate has different pathways that it can enter in the liver during the fed state. All of the following are possible except OA.) it is oxidized to acetyl CoA for fatty acid biosynthesis O B). it can enter the pathway for glycogen biosynthesis O c.) it is a substrate for glucose-6-phosphatase OD. )it is oxidized in glycolysis to provide energy for the bodyQuestion 1: When the CAC is run in reverse by microorganisms that use it to fix carbon, the citrate synthase reaction is different and is catalyzed by an enzyme called ATP-citrate lyase. Write the reaction catalyzed by ATP-citrate lyase, then briefly (in one sentence) explain why the use of different chemistry (different from the ‘normal’ direction) makes sense here.
- QUESTION NO. 1L-Carnitine is synthesized primarily in the liver but also in the kidneys and then transported to other tissues. It is most concentrated in tissues that use fatty acids as their primary fuel, such as skeletal and cardiac muscle.

L-carnitine shuttle is an example of A. ion driven active transport B. facilitated diffusion C. simple diffusion D. ATP driven active transportE. symport F. antiportQUESTION NO.2 Statements: (1) Glucose is both a hexose and a aldose. (2) There can never be more than three enantiomers for a molecule.

You decide to test aromatase from a particular cell, and oops, your lab partner admits he drastically increased the pH in all the test tubes. Which of the following is a likely result? a. The enzyme will be denatured and the substrate will not bind to the active site. b. The enzyme will convert testosterone to estrogen at a faster rate. c. The mistake will have no effect on the experiment, because enzymes are not sensitive to pH. d. The free energy will be lowered and the reaction will not proceed spontaneously.
- QUESTION 26 During gluconeogenesis, whereby liver cells convert pyruvate to glucose, Fructose-6-phosphate (F6P) is converted to Glucose-6-phosphate (G6P).

(1fasting state.Question 9 - Under anaerobic conditions in the muscle, lactate dehydrogenase catalyzes the reaction converting pyruvate to lactate. What is the metabolic reason for this fermentation reaction? It is necessary to reduce pyruvate before it can be converted to acetyl-CoA and enter the citric acid cycle in muscle. NAD* must be replenished for glycolysis to continue. The reaction creates NADH which can produce additional energy in the electron transport chain. O Lactate is more oxidized than pyruvate.Question No. 1 Give the advantages and disadvantages of submerged fermentation and solid state fermentation. Give two examples of acetic acid fermentation.
