The energy is traveling through pigments until the it reaches the reaction center. To boost the electron to a high level the energy would transfer to p680. After the energy being transferred its then passed to an acceptor molecule which would replace an electron from water. O2 would be

Photochemistry From Wikipedia‚ the free encyclopedia Jump to: navigation‚ search Illustration of the electromagnetic spectrum. Note the visible spectrum‚ as well as ultraviolet and infrared regions. Photochemistry‚ a sub-discipline of chemistry‚ is the study of the interactions between atoms‚ small molecules‚ and light (or electromagnetic radiation).[1] The pillars of photochemistry are UV/VIS spectroscopy‚ photochemical reactions in organic chemistry and photosynthesis in biochemistry

The spectrophotometer includes a light bulb‚ a reflector‚ and a detector. When a sample is in place and the chamber lid is closed‚ light from the light bulb passes through it. The detector measures the amount of light

A third membrane system within the stroma forms flattened stacks called thylakoids‚ which in some places are stacked to from grana. The space within each thylakoid is believed to be connected to the space within every thylakoid‚ thereby forming an inner compartment within chloroplast called the thylakoid space.

Lil Dejay C4 2/10/14 Photosynthesis: Making Energy Chloroplasts Photosynthesis is a process in which sunlight energy is used to make glucose. The site of photosynthesis is in the chloroplast – an organelle found in the leaves of green plants. The main functions of chloroplasts are to produce food (glucose) during photosynthesis‚ and to store food energy. Chloroplasts contain the pigment‚ chlorophyll. Chlorophyll absorbs most of the colors in the color spectrum‚ and reflects only green and yellow

photosynthetic capability of chloroplasts. As light intensity increases‚ it is apparent that the rate of photosynthesis begins to decrease until a certain level of light saturation. If the intensity extends over a certain tolerance level‚ photo inhibition occurs. The light used for photosynthesis requires a specific wavelength for the pigments in chloroplast to absorb it. Light independent reactions occur in the stoma of the chloroplast whereas the light reactions occur in chloroplasts that sit on the thylakoid

Mixtures contain two or more substances that are not in a fixed ratio‚ and while some mixtures‚ such as concrete‚ are useful‚ others including salt water‚ are not as useful to us. Filtration‚ distillation‚ paper chromatography‚ and centrifugation are just a few methods used for separating mixtures. There are many methods of separating mixtures. A more commonly known and used method is filtration. Filtration separates mixtures using filter paper‚
