BIO_SC 1010 Lecture Notes - Lecture 11: Photosynthetic Reaction Centre, 3Gp And 3G2, Atp Synthase
Document Summary
Stomata: pores in leaves that allows for the exchange of carbon dioxide and oxygen. Thylakoids: small membrane sacs where chlorophyll (the pigment that is used to harvest solar energy) is stored. photo step chloroplasts capture energy of sunlight and use it to make atp and nadph and splits water. synthesis step -- combine captured energy converts co2 into sugar does not require light. Radiation energy: energy that travels through space as waves. Wavelength: the distance between waves from peak to peak the shorter the wavelength, the more energy. Electromagnetic spectrum: the range of radiation energy includes radio waves and gamma rays (invisible) along with light. Chlorophyll absorbs photons and converts it to chemical energy. Photosystems: clusters of pigment molecules capture photons of light located in the thylakoid membrane contain multiple pigments chlorophyll a: absorbs blue/violet and red chlorophyll b: absorbs blue and orange.
