2. An herbicide called Paraquat blocks the flow of electrons at the early electron acceptors of Photosystem I. Describe and name a specific molecular product of the light reactions that would not be formed. Name and describe a specific process of the Calvin cycle that would be affected. (2pt)

Information that might be useful First Law of Thermodynamics: The total amount of energy of an isolated system is constant; energy can be transformed from one form to another, but can be neither created nor destroyed. Second law of thermodynamics: With every energy transfer or transformation, some energy is degraded (lost, or made less useful), increasing the disorder of the universe and decreasing the energy that is available to do work. The energy of a photon (E) = hc/dl/h = a constant (Planck's constant) c = the speed of light, 000the wavelength of light
