iHub - Photosynthesis Simulation

screenshotPhotosynthesis Simulation

The computer simulation shows a representation of two parts of the process that makes up photosynthesis: light reactions and dark reactions The start of the light reactions are represented by the breakdown of 2 water molecules into 1 oxygen molecule in the presence of light being absorbed and the resulting transfer of the hydrogen atoms to the inside of the chloroplast. When this happens, electrical charges (or lighting bolts) will be shown inside of the chloroplast in the simulation; this is to represent the idea that some sort of potential or electrical energy to is being built up in the chloroplasts. The dark reactions are represented when 2 carbon dioxide molecules are converted into 1 oxygen molecule, and the rest of the atoms are used to build a larger molecule of carbon, oxygen, and hydrogen atoms (harvested from the light reactions). This growing molecule of C, H, O eventually forms into glucose which is then released from the chloroplast. Because this process is modeled in two parts, the total number of oxygen molecules produced may exceed the number of carbon dioxide molecules used up at some points in the simulation. But this would be consistent with the two part set of steps (light reactions and dark reactions) that occur in photosynthesis.
