What is cyclic electron flow? Where does it occur? It uses photosystem I but not photosystem II. Electrons cycle back. It occurs in light reaction(thylakoid disk). What is non-cyclic electron flow? Where does it occur? electrons do not return to the chlorophyll from which they originated. ATP, NADPH and O2 are produced. It occurs in the thylakoid membrane. Involves PS1 and PS2. What happens during Photosystem I? a light capturing unit located in the thylakoid membrane. It has two molecules of P700 chlorophyll a at its reaction center. What happens during Photosystem II? one of the 2 light capturing units in a chloroplast's thylakoid membrane. It has 2 molecules of P680 chlorophyl a at its reaction center. Where are PSI and PSII located? They are located in the thylakoid membrane. What are Hydrogen ions pumped into? the thylakoid space. What does cyclic electron flow produce? ATP What does non-cyclic electron flow produce? ATP, NADPH and O2 Where is the Calvin Cycle located? occurs in the stoma of the chloroplast. What is the end product of the Calvin Cycle? Glucose and water. The photosynthetic pigments are arranged into photosystems located where? Thylakoid membrane. What are the products of the light dependent phase of photosynthesis? Oxygen, ATP and NADPH. What is the name of the electron carrier produced in the light dependent phase of photosynthesis? NAD+ The energy needed to drive the reactions of the light independent phase of photosynthesis is derived from ATP. What’s the difference between local regulation and distant regulation? Local: works b/w cells located near each other .

The distant: impact cells located some distance from each other. What are the cytoplasmic connections between adjacent cells called in plants and animal cells? Which type of signaling produces messengers which influence many adjacent cells? synaptic signaling. Which type of signaling produces messengers that regulate distant cells? What is synaptic signaling? Is a response in brain. It is the communication b/w the neurons (cell) in brain. What is the function of a protein kinase? Protein kinases (PTKs) are enzymes that regulate the biological activity of proteins by phosphorylation of specific amino acids with ATP as the source of phosphate, thereby inducing a conformational change from an inactive to an active form of the protein. What is binary fission? cell division in prokaryotes. What are the three stages in cell signaling? Reception: In this stage the signal molecule is detected by the receptor protein of target cell. The signal molecule generally comes from outside and is new to the target cell, where as the receptor molecules/proteins are located outside/ inside to the target cell. In other terms reception can be defined as the target cell detection of signal molecule that is coming from outside of the cell.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
