Pond weed was placed in a test tube containing a solution of sodium hydrogen carbonate, and had its end cut; light was placed 50 cm away and four colors were tested (clear, red, blue, and green). After placing the light, the pondweed was given a certain amount of time to adjust before counting the bubbles, bubbles were counted for 1, 3, and 5 minutes. Only the bubbles that came out of the cut end was counted to represent the rate of photosynthesis. Below is the tabulated results. What are the possible factors or errors that could have affected clear/white light to have lower photosynthetic activity? In theory this should have the highest rate.To assess photosynthesis, we relied heavily on a spectrophotometer to measure the color intensity of DCPIP in our solution. We set the spectrophotometer at wavelengths in the visible spectrum. What is the approximate wavelength range (in nm) for the visible spectrum? For example, the ultraviolet spectrum wavelength range is approximately 10-400 nm

- DRAW a curved arrow mechanism for photosynthesis with the following steps. Step 1: Absorption of sunlight and excitation of chlorophyll molecules Step 2: Transfer of energy to reaction center chlorophylls, which lose an electron and become oxidized. Step 3: Electron transfer from oxidized chlorophylls to an electron acceptor, such as a quinone molecule Step 4: Electron transfer from the quinone molecule to a chain of electron carriers, such as cytochromes, which generate a proton gradient across the thylakoid membrane Step 5: ATP synthesis by ATP synthase using the energy of the proton gradient. Step 6: Transfer of electrons from the electron carriers to the enzyme rubisco, which catalyzes the carboxylation of ribulose bisphosphate (RuBP) with CO2, forming an unstable 6-carbon intermediate. Step 7: Cleavage of the 6-carbon intermediate into two 3-carbon molecules, which are phosphorylated by ATP and reduced by NADPH to form glyceraldehyde-3-phosphate (G3P) Step 8: Conversion of G3P to…Melvin Calvin and Andrew Benson determined the steps in the light-independent reactions of photosynthesis by exposing the green alga Chlorella to CO2 labeled with the radioisotope carbon 14. By looking at which compounds the C14 ended up in, they were able to identify all intermediates in this cyclic pathway. Why did they predict correctly that the same set of intermediates would be formed in the light reaction in land plants?Compare the light-dependent reaction with the light-independent reaction.
