Mass Spectrometry (MS) used to identify the mass of molecular fragments by taking the m/z difference (technique that ionizes and fragments molecules; these ions then accelerate towards a magnet depending on their mass) Oxidation States increasing number of C-O bonds= more oxidized (oxidation state increases) increasing number of C-H bonds= more reduced (oxidation state decreases) Oxidation-Reduction (Redox) Reaction electrons are transferred from one atom to another (OIL R...

Increase Ventricular filling -> Increased Stroke volume -> Increase cardiac input -> _____ Vascular Resistance - Answer - Decreased *Same for reversed Reduced ventricular filling would lead to LESS blood being expelled from the ventricle with each contraction and ______ CO. - Answer - Decreased Compared with healthy individual's ECG, the patient's ECG shows _____ waves of AV depolarization over the same time period. *increased # of APs fired from patient's SA and AV nodal...

Paramagnetic - Answer - Unpaired electrons in the electronic configuration of an atom or ion, which end up interacting with each other in a magnetic field Diamagnetic - Answer - Paired electrons in the electronic configuration of an atom or ion, which will NOT interact with each other in a magnetic field Electron capture - Answer - An alternative form of positron emission (B^+ decay) Reactivity of forming Ionic Bonds - Answer - This increases as the Ionization Energy (IE) decreases I...

What concept refers to the amount oxygen necessary to bring the muscle back to its resting? Hint: It's equivalent to the difference b/n the amount of oxygen actually required for physical activity and the total amount of oxygen used - Answer - Oxygen debt or Excess post-exercise oxygen consumption (EPOC) What do muscles need to contract? - Answer - ATP What is the primary source of ATP in muscle fibers during vigorous, long-term exercise? - Answer - Aerobic respiration - generates more...
