The synthesis of lauric acid
Consider the synthesis of lauric acid (12:0) in a coconut tree, a C3 plant. This will require you to think about the carbon fixation pathway and fatty acid synthesis. © 2022, Arizona State University How many molecules of acetyl CoA are required for the synthesis of lauric acid? Since the acetyl CoA is produced from glucose, how many molecules of CO2 must be fixed to make this acetyl COA (think about how much glucose is needed to make the acetyl COA)? How many NADPH and ATP are required to make the necessary glucose? How many photons are required by each photosystem to produce the NADPH? How many protons are pumped in conjunction with NADPH production? If the coconut tree has an ATP synthase with 14 c subunits, how many protons are required to produce the necessary ATP? Use the answers to the above two questions to determine the number of protons that must come from cyclic electron flow. How many additional photons are required by the photosystem to produce the needed protons?
