question 1
1. Your experiment used the decolorization of DCPIP to indirectly measure rates of photosynthesis in the isolated chloroplasts. Why does this work? To answer this, first provide a detailed description of the Linear Electron Flow pathway as it occurs in chloroplasts, and then explain what part of this pathway actually decolorizes DCPIP and why this only occurs when light is shining on the chloroplasts. Feel free to research this before answering. Provide the URL of any source(s) you...

mestion Completion Status: Why did I suggest that the secret to life is electrons and protons? A. Because redox reactions are necessary for all of the reactions in live cells and these redox reactions require both H+ and electrons B. Because electrons carry a negative charge and protons have a positive charge C. Because most (not all) cells need electron transport and H+ gradients to make ATP D. Because electrons are necessary for the electrical responses of the cell (like...
