BIOL 1500 Chapter Notes - Chapter 5: Electromagnetic Spectrum, Chlorophyll, Pigment
Document Summary
5. 1 life depends on photosynthesis: autotroph - self-feeder uses inorganic substances, heterotroph obtains carbon consuming preexisting organic molecules, energy, raw materials and oxygen support most heterotrophs. 6co2 + 6h20 ---------------- c6h12o6 + 6o2: more than half of the world"s photosynthesis occurs in the vast oceans (algae and bacteria) Infrared radiation: too little energy to be useful to organisms, most energy converted to heat, plant cells have pigment molecules, chlorophyll a, most abundant. Opening through which a leaf exchanges gases with the atmosphere. A stack of thylakoids suspended in a chloroplast. A pancake-shaped compartment within a chloroplast; site of the light reactions. The lipid bilayer in which photosystems are embedded. Cluster of pigments and proteins that participate in the light reactions of photosynthesis. The fluid inside the chloroplast; site of the carbon reactions. Carbon in co2: oxygen attracts electrons stronger than carbon therefore moving electrons from oxygen to carbon requires light energy.
