Congenital sucrase-isomaltase deficiency (CSID) is a genetic condition that prevents the metabolism of cane sugar (sucrose). This condition can result in, among other things, abdominal cramps and bloating, diarrhea, vomiting, and increased susceptibility to upper respiratory tract infections.
A) Suggest a possible molecular mechanism underlying this condition.
B) Based on the mechanism described above, offer a hypothesis as to why this condition may be more severe in some individuals than others.
Some are unable to taste thiourea and PTC. DNA sequence results for these individuals show a normal predicted amino acid sequence for the TAS2R38 gene. Provide an explanation that can account for insensitivity to thiourea.
(a) First assuming a mutation involving the TAS2R38 gene
(b) Then assuming a mutation in a gene other than TAS2R38
Cite example of actions wherein the principle of double effect can be applied. Explain the coditions that must be met in such action or situation.

- 1. Pepsinogen (an inactive form of the enzyme) that forms in the main cells of the stomach has a molecular weight of 42,000 D. In the gastric juice, the pepsinogen turns into the active enzyme pepsin, while its molecular weight decreases to 35,000 D. Explain the mechanism of regulation of enzyme activity.
