What number corresponds to the period of ventricular repolarizaton?

This figure shows the O2 content (mL O2/100 mL blood) and % Hb-O2 saturation under normal, carbon monoxide and severe anemic conditions.   A. For resting systemic tissue, what is the Hb-O2 saturation for someone who is anemic and someone who has carbon monoxide poisoning?   B. Under normal conditions, if the partial pressure is 40 mm Hg, what is the best estimate of the amount of O2 (ml O2/100 mL) that is released from blood as it circulates through systemic tissues?   

What molecule is considered the energy currently of the cell; it donates its energy by breaking one of its bonds?

A drug is administered that blocks the potassium-channels embedded in the sarcolemma of cardiac muscle cells (i.e., diminishes the ability for K+ to flow across the membrane). How will this affect the length of the refractory period? Explain your reasoning. [Answer in 2-3 sentences]
