BIOC31H3 Study Guide - Final Guide: P680, Cellulose, Vacuole
Document Summary
Thylakoids (h20 is oxidized): h20 + light energy o2 + atp + nadph, stroma (carbon fixation, c02 is reduced) = c02 + h20 (ch20) + o2 keq= 10-500 (light driven redox process: hill reaction : thylakoids were isolated & given light. O2 was released and reduction of fe happened rather than c02 reduction. 4fe3+ + 2h2o 4fe2+ + o2 + 4h: artificial electron acceptor showed how photosynthesis & respiration worked, light has electric and magnetic field components (electromagnetic). Energy moves in wave w/ defined wavelength and frequency. Energy moves as particle in packets of energy called photons (quantum). Energy of photon is inversely related to its wavelength: electromagnetic spectrum: shows type of radiation. , f, e (gamma, xrays) . The visible spectrum can be utilized and absorbed by plants ( = 400-700nm: fig 7. 3 solar spectrum and relation to absorption of chlorophyll of light energy.
