Chloroplast structu re The photograph below is an elodea leaf X 400. Individual cells are clearly visible. The tiny green structures within the cells are chloroplasts. Click the image (above) to enlarge it. Thylakoids are membranous disk-like structures that are stacked together in larger structures that resemble stacks of coins. Chlorophyll and carotenoid pigments are located in the membranes of the thylakoids. The thylakoid membranes also contain the electron transport system. The diagram below is a drawing of a chloroplast showing the thylakoids. The fluid-filled space surrounding the grana is the stroma . Many enzymes needed in

Unformatted text preview: photosynthesis are found in the stroma. 2 Sets of Reactions Light-Dependent Reactions The light-dependent reactions require light. These reactions occur in the thylakoid membrane. They produce ATP and NADPH , which are needed to produce glucose in the light-independent reactions (below). Notice how the equation for photosynthesis relates to the reactions shown in the diagram below. 6CO 2 + 6H 2 O + Energy → C 6 H 12 O 6 + 6O 2 Light-Independent Reactions Light-independent reactions occur in stroma of the chloroplast in light or dark conditions. They function to reduce CO 2 to glucose....

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
