Each of the ff. involves a disorder in the function of an organelle or other cell structure. Identify the cell organelle or cell structure involved and indicate whether it is likely to be underactive or active.
a) A baby is placed on a low phenylalanine diet as his newborn screening results revealed that he inherited phenylketonuria.
b) A girl suddenly felt weak and manifested cyanide poisoning symptoms after ingesting undercooked cassava which contains cyanoglycosides.
c) A man develops pleiomorphic liposarcoma (rare cancer). The cause of the problem is a hard mass of cells in his right inner thigh that rapidly increased in size in a matter of 2 months.
d) A male chef learns that he is infertile because his sperm are non-motile.
