Carotenoids - lipid derivatives, produce pigments in plants and animals , An accessory pigment, either yellow or orange, in the chloroplasts of plants. By absorbing wavelengths of light that chlorophyll cannot, carotenoids broaden the spectrum of colors that can drive photosynthesis. Porphyrins - lipid derivatives, a group of light-sensitive, pigmented, ringed chemical structures that are required for the synthesis of hemoglobin. Complexed with metals usch as iron in hemoglobin and ch...

Hemoglobin O₂ binding affinity decreases under what conditions: - Bohr Effect Low pH (High CO₂ and high H⁺)=> oxygen loads released by hemoglobin if do opposite (decrease CO₂ or H⁺)=> increase affinity for oxygen Haldane Effect - if you increase the pressure of CO₂=> increase CO₂ content in blood. * oxygenation of blood in the lungs displaces CO₂ from hemoglobin=> increase CO₂ removal *Hemoglobin without O₂ acts as blood buffer by accepting H⁺... this will...
