- 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 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. In this regard, L-carnitine plays an important role in energy production by conjugating to fatty acids for transport from the cytosol into the mitochondria. 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.

Show chemical structure for all intermediates.Question 9 Why does acetyl Co-A occupy a central role in cellular metabolism? Question 9 options: Acetyl Co-A is essential to the catabolic process that includes triglyceride synthesis Only amino acids and glucose can be converted to acetyl Co-A since glucose cannot be derived from fatty acids Amino acids, fatty acids and glucose can all be converted to acetyl Co-A Acetyl Co-A is essential to the anabolic process that includes the citric acid cyclQuestion 21>In 1668, Francesco Redi performed a series of experiments on spontaneous generation. He began by putting similar pieces of meat into eight identical jars. Four jars were left open to the air, and four were sealed. He then did the same experiment with one variation: Instead of sealing four of the jars completely, he covered them with gauze (the gauze excluded the flies while allowing the meat to be exposed to air). In both experiments, he monitored the jars and recorded whether or not maggots (young flies) appeared in the meat.What hypothesis was being tested in the initial experiment with open versus sealed jars?A.The type of meat used affects the likelihood of spontaneous generation.B.Spontaneous generation can occur only if meat is exposed to air.C.Spontaneous generation is more likely during the long days of summer.D.Maggots do not arise spontaneously, but from eggs laid by adult flies.
