Which metabolic reaction requires an input of energy? 4. Which metabolic reaction releases energy? 5. Which reaction yields a more complex molecule and is reductive? 6. Which reaction yields a simpler molecule and is oxidative? 7. What are the products of catabolism? Which part of the cell does this pathway take place? 8. What are the products of anabolism? Which part of the cell does this pathway take place? 9. Which reaction is divergent? Why? 10. Which reaction is convergent? Why? 11. How can you relate waterfalls to a mole of glucose? 12. What are the steps in catabolism? 13. What is the common pathway of the degraded complex molecules?What is metabolism? Distinguish between anabolism and catabolism, and give examples of each.metabolize aerobically and anaerobically. refers to pathways that take place in the presence of oxygen. refers to pathways that are the exact opposite, and occur without the use of oxygen. aerobic and anaerobic, to meet demand during different intensities and durations of exercise. .. a high-energy molecule stored in muscle cells, transfers its high-energy phosphate group to to form ATP. is available, several major metabolic pathways take place and together these steps are called This pathway generates a amount of ATP. the production of a amount of ATP from glucose occurs and this There are three different energy pathways, muscles' The next two pathways involve the carbohydrate If If oxygen is process is called TROUSE
- ● ● Explain the importance of energy and entropy for living cells. State the role of enzymes in controlling metabolic biochemistry. Describe how catabolism converts many complex food molecules to a few kinds of catabolites. Explain how catabolism yields energy and how the energy is stored for use. Describe how the energy carriers ATP and NADH transfer energy between energy-yielding and energy-spending reactions. Describe how sugar is catabolized to pyruvate via glycolysis, along with production of ATP and NADH. Explain how pyruvate can be further TCA cycle (when oxygen is available). polized by fermentation or by the Explain how bacterial catabolic reactions are used in clinical tests to identify a pathogen. Define and explain the importance of nitrogen fixationSBI4U 26. Observe the diagram to the right. In the past we've discussed you gain from digestion: 4 cal per 1g of protein 4 cal per 1g of carbs 9 cal per 1g of fats Fats Protelns Carbohydrates Given your knowledge of macromolecules and your new knowledge of aerobic respiration, discuss the entrance point of these molecules into the aerobic respiration pathway and why might you get more/less calories (energy) from different macromolecules. Sugars Glycerol Fatty acids Amino acids Glycolysis: Gluçose Glyceraldehyde- 3-phosphate Pyruvate + Acetyl CoA Krebs cycle Oxidative phosphorylationYou are what you eat. What does this mean? If you eat only celery, will you become a vegetable? Sometimes there are so many words used to describe foods and nutrition, it is difficult to make sense of them. In fact, we do use the food we eat to provide energy and also the building blocks for growth and development. Even after you are fully-grown, your body, just like any other machine, needs to make constant repairs to injured areas and must replace cells that have died. To make sure that the structure of your body is correct and strong, you must provide it with a regular supply of the right building materials. Foods are the building materials for the body. There are six large categories of nutrients in food. These are carbohydrates, protein, fats, vitamins, minerals, and water. Each food you eat not only contains more than one nutrient, but also a different number of calories (energy). Fat, protein, and carbohydrates provide calories, or energy as well as building blocks. Vitamins,…
- goes. In order to summarize Cellular Respiration reactions, draw FIVE big boxes in a line down the middle of your page. Write 1) Glycolysis, 2) Pyruvate Oxidation, 3) Citric Acid Cycle, 4) Electron Transport Chain, and 5) Chemiosmosis inside these boxes. Below each process name write WHERE it occurs. Make arrows going in and out of each box. Write IN and OUT on top of the page above the arrows. Each box represent multistep processes. You are focusing on the INPUTS and OUTPUTS. A. First focus on the flow of ENERGY. For each box write the INPUT and OUTPUT – the molecule(s) or form that contain the potential energy. B. Next, in a different color of ink (or highlighter) focus on the flow of ELECTRONS. For each box write the molecule(s) that carry the electrons from which you are harnessing energy. C. And finally, in a third color of ink (or highlighter) focus on the flow of CARBON. For each box write the carbon molecule (if any) from which you are harnessing energy.Sometimes, ATP is referred to as the “energy-storage molecule.” The cell does not actually store energy as a lot of extra ATP but as glycogen or triacylglycerides. Why do you suppose this is the case?The metabolic process that consumes more energy than any other is ?
- How different metabolic pathways are related to each other?. Write the reaction that links glycolysis and the citric acid cycle. What is the enzyme that catalyzes the reaction?Can you please pick the right answer in each parentheses? Glucose synthesis can derive carbons from a variety of sources including ["fatty acids", "glycerol"], ["cholesterol", "amino acids"], ["lactate", "NADH"], and ["oxidative phosphorylation", "carbon dioxide, photosynthesis"]
