Why do Lewis Bases make good nucleophiles?
To be a Lewis Base, a compound must have a pair of electrons to donate. A good nucleophile needs to readily be able to donate a pair of electrons to an electrophilic species, making a Lewis Bases an ideal candidate.
Describe some differences between hemoglobin and myoglobin? where are each normally located? how are they different in their ability to bind oxygen and carbon monoxide?
Myoglobin is mainly found in muscle tissue and binds carbon monoxide more tightly than oxygen. On the other hand, hemoglobin binds oxygen (in the lungs) more tightly than carbon monoxide
Describe some differences in prokaryotes and eukaryotes.
While prokaryotes don't have membrane-bound organelles or a "true" nucleus, they do have a nucleoid region that houses their single, circular chromosome. On the other hand, eukaryotes do have membrane-bound organelles and a "true" nucleus that houses their numerous linear chromosomes.
