27. Arsenic poisoning can lead to organ failure and death. Though arsenic can inhibit or
interfere with a number of cellular enzymes, arsenic poisoning is thought to be mainly due to
indirect inhibition of enzymes involved in both pyruvate oxidation and the Krebs cycle. As a
result, this compound must be able to enter which cellular compartment?

32. Cardiac muscle cells need to generate significant amounts of ATP to allow for constant
contractile activity. As a result, they primarily depend upon beta-oxidation of fatty acids,
which has a higher energy yield than the catabolism of glucose. What would be the ATP yield
for beta-oxidation of a hypothetical 10-carbon fatty acid?
