Question

1. In the cells in the leaves of an apple tree, photosystem II replaces the electrons lost by photosystem I. A chlorophyll molecule of photosystem II absorbs two _____ and ejects two _____. These pass to the primary electron acceptor and on to an electron transport chain. The electrons pass down the chain and eventually end up replacing the two electrons lost by the chlorophyll of _____. On their way down the electron transport chain, the electrons perform important work. One of the electron carriers in the chain uses the energy released by the electrons to transport _____ ions from the _____ into the space inside the _____. This creates a buildup of H + , a concentration _____ of H + across the membrane. The H + ions then diffuse through the membrane via a protein complex called _____, which captures their energy to make _____. In photosynthesis, this chemiosmotic production of ATP is called _____. How does photosystem II replace its lost electrons? It gets them by splitting _____. When the electrons of photosystem II are jarred loose, the reaction center develops strong attraction for electrons. It obtains them by breaking apart a molecule of _____. This leaves two (H + ) which pass in to the thylakoid space and an ____. This atom combines with another from another water molecule to form a molecule of _____ gas, which diffuses out of the leaf- a product of photosynthesis important to us and other animals.
