Photosynthesis Computer Simulation The Light Dependent Reactions This activity is loaded on the Science Computer Lab computers. It is also available at http://www.mhhe.com/biosci/genbio/biolink/j_explorations/explorations.html Getting Started— Open the Cell Biology and Genetics icon. Wait for the program to load. Click on Menu . Click on Photosynthesis . The Model —You will see a diagram of a thylakoid within a chloroplast . Embedded in the membrane of the thylakoid are five integral proteins and sitting along the inner and outer edges of the thylakoid membrane are six peripheral proteins . These proteins perform several functions to drive the light dependent reactions of photosynthesis. The Controls —To the left of the thylakoid model is a group of two controls (light intensity and wavelength) and three gauges (time, # of ATP, and % maximal ATP). The light intensity scale is in lux (10 2 ). Lux stands for lumens/m 2 . It is one of a few units used to measure light intensity. To save space, 40 lux on the simulation scale is actually 4,000 lux and 200 lux is
