Explain how the C-H stretching frequencies of the cycloalkanes change from cyclobutane to cyclopentane to cyclohexane. Define this observation.
Catalyzes the synthesis of ATP when protons flow down their electrochemical gradient 4. Utilizes ATP hydrolysis to pump protons down their electrochemical gradient I picked 1/3/4, because 2 uses protons and not electrons.
Explain what happens to the atomic number of a nucleus when positron emission occurs
