BIOL 150 Chapter Notes - Chapter 10: Quinone, Gluconeogenesis, Carboxylation
Document Summary
Photosynthesis (use of sunlight of manufacture carbohydrate) Co2 + h2o + light energy produces (ch2o)n + o2. Van neil"s work was crucial for 2 reasons: Showed that these bacteria, h2s and co2 don"t combine directly during photosynthesis. Showed that oxygen atoms in co2 are not released as o2. Calvin cycle (reaction that reduces co2 and produces sugar) Stroma (fluid-filled space between thylakoids and inner membrane) Pigments (molecules that absorb only certain wavelengths of light) Wavelength (distance between 2 successive wave crests (or water troughs)) Electromagnetic spectrum (range of wavelengths of electromagnetic radiation) Visible light (electromagnetic radiation that humans can see) Photons (particle-like nature of light; discrete packets) 2 major pigment classes in plant leaves. Action spectrum (wavelengths that drive light-capturing reactions) Absorption spectrum (measure how wavelength of photons influences amount of light absorbed by pigment) Photosystem (antenna complex and reaction center create this)
