BIO203H5 Lecture Notes - Lecture 2: Carbon Fixation, Chlorophyll, Pyrrole
Document Summary
What is photosynthesis: it is the acquisition of carbon, plants use the energy of the sun to produce organic compounds, conversion of carbon from carbon dioxide to organic carbon (ch2o) using light as the source of energy. Where is it (cid:272)ontained: the pigment that absorbs light for photosynthesis is chlorophyll, contained in chloroplasts, two types: Yes, there are other pigment sin the chloroplast that absorb light called carotenoids. Part of the membrane system (the liquid matrix between the grana is the stroma) What are thylakoids: hollow balloons stacked on each other, membrane structures that absorb light and use the energy from light to do work. What is light: released from the sun as electromagnetic radiation, light has wavelike properties and distances between wave peaks differ (wavelength) Radar, micro, radio waves, can be km in length. It is the wavelengths that the human eye is able to see occurring from 400nm to 700nm.
