Could someone please help me answer these 5 biology questions related to photosynthesis. 1. If NADP+ is not available as the final electron acceptor, where will the electron go? Select one: a. The electron is ejected into the stroma. b. The electron is returned back to the photosystem through a series of proteins. c. The electron is donated to H2O. d. The electron is recycled directly back to the reaction center pigment. 2. Which of the following is NOT true...

Lab 8 Spring 2020 The Light Reactions The light reactions begin with the photolysis of water. Photolysis refers to the process by which, in the Intact thylakoid membranes and light. water is split into oxygen protons and electrons. Therefore, was primary electron donor in photosynthesis. Conversion of water, a very stable molecule, to oxygen is er unfavorable and would not occur to any significant extent without input of light energy in photosystem e process by which,...
