- At the beginning of the light reaction, light excites electrons. Explain.arrow_forwardIf a voltage is applied to two platinum wires (electrodes) immersed in water, then water molecules become split into H2 and O2 gas. At the negative electrode, electrons are donated and H2 gas is released; at the positive electrode, electrons are accepted and O2 gas is produced. When photosynthetic bacteria and plant cells split water, they produce O2, but no H2. Why?arrow_forwardThe transfer of electrons in a photosystem creates a membrane potential with a _______ concentration of H+ molecules on the inside of the membrane and a ______ concentration on the outside of the membrane. A. higher; lower B. lower; higherarrow_forward

Jiro is performing an experiment on photosynthesis using Hydrilla plants. He wants to know which light spectrum would facilitate faster photosynthetic rate. He asked Elea and Nina to help him plan and set-up the experiment. Elea plans to test four light spectra by using four different colored light bulbs accordingly. Nina said they need two controls, one without light source and one under natural light for comparison. They will be using Bromothymol Blue, a color changing carbonic acid indicator as a substrate for the Hydrilla. This indicator, which is originally blue in color, changes to yellow when infused with carbon dioxide and forming carbonic acid. The assumption is that when the Hydrilla plant submerged in the indicator starts to photosynthesize, it will slowly turn the yellow color (previously infused with carbonic acid through blowing carbon dioxide into the solution) back to blue as plants use carbon dioxide during the process. They will check which of the setups will…arrow_forward
