Cellular Respiration Understand the differences between aerobic and anaerobic processes. How do you identify a compound that is reduced or one that is oxidized? Know how to identify the reducing/oxidizing agent. Understand how to identify something as an electron donor/acceptor. Also know specific molecules used in respiration that can act as donors/acceptors. What are the three different stages of cellular respiration? Can they occur in all organisms? Which stage of respiration produces the most ATP? Which produces the least? Which stage(s) must invest energy to create energy? Where does each stage of respiration take place? In the stages of cellular respiration, there are two different processes that are used to create ATP. What are these two different processes and how do they differ? What are the net products of Glycolysis? Before it can enter the citric acid cycle, the product of glycolysis must be converted to what? What are the net products of the citric acid cycle? The citric acid cycle technically generates the same amount of ATP as glycolysis. While ATP creation is an important part of this cycle, what is the primary purpose of this particular stage of respiration? Name one specific class of proteins that play an important role in electron transport. What enzyme is used in oxidative phosphorylation to actually generate ATP molecules and how does it function? What percentage of the energy in a glucose molecule is actually transferred to ATP during respiration? What happens to the rest of the energy? What is the difference between anaerobic respiration and fermentation? Know the difference between obligate and facultative anaerobes. Understand how fats can also be broken down to be used in cellular respiration. Know why a process like cellular respiration would need to be regulated by an inhibitive feedback loop. Photosynthesis Know the difference between an autotroph and a heterotroph. Important terms that you should know include: Chlorophyll Stomata Mesophyll Thylakoids Stroma If Photosynthesis is carried out in any of the above complexes, know in which ones it occurs, and also know where the light dependent and independent reactions are carried out. What is the purpose of the light dependent and independent reactions? What is produced at the end of each set of reactions? Understand the importance of each of the following types of pigments: Chlorophyll a, chlorophyll b, carotenoids. Be able to discern between the structure of chlorophyll a and b. Know the purpose of photosystems and their importance to the light dependent reactions. What is the order of the photosystems? What wavelength of light does each absorb? Understand the difference between linear and cyclic electron flow, as well as the products produced by each. What is P680? What is P700? What is the product of the Calvin Cycle and how many times must the cycle occur to create one molecule of this product? What are the three phases of the Calvin Cycle? If excess sugars are produced by photosynthesis how and where are they stored in plants? Understand the relationship that the by‐products or products of each stage of photosynthesis have with the other stage. In other words, if the Calvin Cycle produces certain by‐products, are those by‐products utilized by the light dependent reactions? Cell Cycle: 1. Know the definition of all of the words in bold. 2. Know the difference between similar key terms (ex. Chromatin, chromosome, chromatid, centromere, centrosomes, centrioles, etc). 3. Know the phases (Mitotic & Interphase) and the subphases (G1, S, G2, pro, prometa, meta, ana, and telo) of the cell cycle/cell division, and know what happens in each. 4. Which part of the cell cycle last the longest amount of time: Interphase or M phase? 5. Be able to identify different stages of mitosis in both plant and animal cells (either microscope pictures, or drawn pictures). Know the key events that occur in each stage, distinguishing it from the others. 6. At the end of cellular division, know what the name of the process is that results in the cytoplasm dividing as well as what the structure is called that forms when this event occurs. Know the differences, at this step, between plant and animal cells. 7. Know how many cells are produced at the end of mitosis as well as how those material. 8. What difference(s) exists between somatic cells and gametes? cells compare with their parent cell and each other in regards to their genetic 9. Scientists hypothesize that the signals that carry out most of cellular division occur in a specific region of the cell. What region of the cell is this, and how did the scientists arrive at this conclusion? 10. What safety measures does a cell have that could prevent it from e ntering the cell cycle if it is not prepared to do so? At what sub‐phases are these measures implemented? 11. What are some of the various external signals that can affect a cell’s willingness to divide? 12. Know what can go wrong in regards to the mechanisms from the two previous questions that can cause a cell to become cancerous. 13. Know the difference between malignant and benign tumors in regards to their severity.
