Product Details

Capture electron transfer during photosynthesis—as well as student interest—using a redox indicator. Photosynthesis is the process that traps the energy from sunlight to convert carbon dioxide and water to glucose and oxygen, as well as ATP. In this revealing lab activity, students monitor the color change of an indicator (DCPIP) to investigate the rate of photosynthesis and explore the actual reactions of the electron transfer chain during the light reactions of photosynthesis. By constructing a standard curve for the concentration of DCPIP, students will visually observe the reduction of DCPIP that occurs when it intercepts excited-state electrons produced by the absorbance of light energy by chloroplasts. A fascinating inside look into the actual mechanism of photosynthesis! Super Value Kit is complete for 5 classes of 30 students working in pairs. Fresh spinach, a blender, 0.1-g precision balance, ice, a hot water bath, and several strong light sources, such as an overhead projector or 150 W lamp, are required but not provided. The experiment may also be performed using a spectrophotometer, if desired.
