Animals cannot convert fatty acids into carbohydrates. the net synthesis of one mole of oxaloacetate from two moles of acetyl-coa by the citric acid cycle does not occur, because one mole of oxaloacetate is used in the cycle for each mole generated. with two additional enzymes not found in animals, plants are able to convert two moles of acetyl-coa into one mole of oxaloacetate. this process is called the glyoxylate cycle, and it occurs in organelles called glyoxysomes. complete both parts of this question. a) identify the enzymes of the glyoxylate cycle, shown below, by dragging the enzyme name to the appropriate place in the cycle. (not all the enzymes are used).

Calculate the change in entropy if br2(l) is converted into gaseous br atoms. s° for br2(l) = 152.2 j/(mol•k) s° for br2(g) = 245.5 j/(mol•k) s° for br(g) = 175.0 j/(mol•k)

Two nitro no2 groups are chemically bonded to a patch of surface. they can't move to another location on the surface, but they can rotate (see sketch at right). it turns out that the amount of rotational kinetic energy each no2 group can have is required to be a multiple of ε, where =ε×1.010−24 j. in other words, each no2 group could have ε of rotational kinetic energy, or 2ε, or 3ε, and so forth — but it cannot have just any old amount of rotational kinetic energy. suppose the total rotational kinetic energy in this system is initially known to be 32ε. then, some heat is removed from the system, and the total rotational kinetic energy falls to 18ε. calculate the change in entropy. round your answer to 3 significant digits, and be sure it has the correct unit symbol.
