21. Does the change in gravity affect respiration, making it harder to breathe in space than on Earth? Does physical fitness play any part in one's ability to breathe in space? (LM) (A K2S Question)

Physical exertion either due to gravity, the suit, or required work will dictate the respiration rate. The more fit a person is, the better he or she will be able to handle the work load that is demanded. This then will mean a more efficient use of oxygen.
