Unformatted text preview: Photosynthesis - II Lecture #17 Part 1 - Review and extension of the Light Reactions. Part 2 - The Calvin Cycle. Part 3 - Summary (the big picture). Chapters and pages see previous lecture Remember EXAM #2 is approaching - rapidly. Lecture 16-Objectives Review chloroplast structure and the function of its major components. Recall how photosynthetic and non- photosynthetic eukaryotes might have evolved. Compare and contrast proton motive force in mitochondria and chloroplasts. Recall the structure of the ATPase and recount its function. Know the function of the accessory pigments. Lecture 16-Objectives Know the function of rubisco. Know qualitatively what is achieved at each of the three stages of the Calvin cycle The Big Picture Heterotrophic cells can not productively fix C. More of The Big Picture Chloroplast Structure Chloroplasts contain vesicle-like structures called thylakoids. A stack of thylakoids is called a granum. Stroma is fluid between the chloroplasts outer membrane and its thylakoid disks. The thylakoid disks are rich in the pigment chlorophyll. Both mitochondria and chloroplasts have DNA, RNA, and protein synthesis machinery. These organelles are somewhat autonomous. A Point About Evolution Chemiosmosis in mitochondria and chloroplasts Matrix Intermembrane space Photo phosphorylation Thylakoid space Stroma The proton motive force to synthesize ATP is universal in biology A molecular motor The Light Reactions...
