Rates and Nature: A Closer Look In chloroplasts plants use photosynthesis to convert water and carbon dioxide into sugars and oxygen. The overall reaction is: n C O H O [C n H O n-1) n O (n+1) H O sucrose if n = 12, or starch if n = large The sequence of reactions leading up to the above overall reaction is complicated, but it would never happen on its own if the rate was not catalyzed by chlorophyll molecules. When light strikes chlorophyll molecules, they lose an electron, which is picked up by a molecule that helps link up CO molecules. The electron is eventually returned to chlorophyll. The molecule that ultimately loses its electrons for the sake of chlorophyll is water: 2 H O + O Figure Chloroplast Note that the above reaction releases oxygen, which is why plants release O while growing. The reaction also concentrates H on one side of the membrane in those little green disks shown in Figure 1. That allows an energy carrying molecule, ATP, to be made, and the energy is invested in the production of sugars. Note, that after all is said and done, chlorophyll is available again to absorb more light, and to start the whole cycle again. True catalysts speed up reactions without being consumed.

Switch to full desktop version Christine Arpe Gang Green Thumb: New magazine, 'Photosynthesis,' plants 'garden of words and photos' By Christine Arpe Gang Published Friday, July 30, 2010 Stephanie Miller hopes to plant a few seeds with her new quarterly magazine, Photosynthesis. Not the kind that turn into plants. She leaves that to her husband, Chris Cosby, greenhouse manager and curator of My Big Backyard at the Memphis Botanic Garden. "The magazine is a garden of words and photos," said Miller, a painter and photographer who has spent the past 10 years as a stay-at-home, home-schooling mother of two daughters. After looking through lists of plant-related words, she chose the magazine's title because it reflects its essence: "It's about green life and bringing together a more deeply synthesized horticultural community." Photosynthesis, you may recall from grade-school biology, is a chemical process that enables plants to capture the sun's energy and turn it into food and oxygen. In the inaugural summer issue, Photosynthesis features stories and pictures of two local gardens: Bickie McDonnell's East Memphis garden and Diane Meucci's garden at her nursery, Gardens Oy Vey in Arlington. Both are lush, mature gardens with well-chosen plants in harmony with each other and the entire landscape.
