Sample Data

Front Describe the role of pigments in the thylakois
Back Chlorophyll a, 2 molcules in each reaction centerChlorophyll bCaroteneXanthopyllAll save for chlorophyll a channel energy from light to chlorophyll a to increase the energy level of electrons in chloropyll a
Front How does pyruvate enter the mitrochondria
Back when oxygen is available, pyruvate enters to take part in the link reaction
Front outline the role played by the inner membrane of the mitrochondria
Back Where the ETC releases energy to pump protons into the intermembrane spaceWhere ATP synthase is present for ATP productionCristase (infoldings) of membrane increase surface area for many ETCs and ATP synthasesimpermeable to H+ ions to maintain a high H+ gradient in the intermembrane spaceSite of oxidative phosphorylation/chemisomosis
