Trace the path of an electron from its origins atthe reaction center of photosystem II to its final electronacceptor at the end of photosystem I. Be able to name the mainmolecules involved in the process (this does not include theindividual molecules within the ETCs). Describe any actual‘work’ that the electron […]
In constructing an oligonucleotide probe based on information from a protein’s sequence, one often chooses (if possible) regions of a sequence containing tryptophan or methionine residues.Why? a. The synthesis of most proteins starts with methionineor a derivative there of, so a methionine codon assures one willstart at the beginning of […]
1) Lactose is a disaccharide of glucose and galactose, and its digestion requires the actions of the enzyme lactase If the lactose is taken in as part of the diet, but not digested by lactase, this sugar is then metabolized by bacteria in the intestine, leading to the symptoms of […]
Suppose that an enzyme uses a catalytic mechanism in which a functional group on the enzyme has to accept a proton from the intermediate formed in the first chemical step. The pKa of that basic functional group on the enzyme is 8.0, and is the only pKa apparent on a […]
