- Cellular respiration is divided into 3 phases, each yielding a different amount of energy. A yeast cell is placed in an open flask in the laboratory. The flask contains sugar, water, and grape juice. b. The flask is then sealed with an airtight stopper. Describe which phases of cell respiration will take place now and list the amount of energy that will be made during those phases. *Which of the following DOES NOT describe Cellular Respiration? * a. It provides cells with the energy they need to function. b. Cellular respiration is essential to both eukaryotic and prokaryotic cells because this biochemical energy is produced to fuel many metabolic processes, such as biosynthesis, locomotion, and transportation of molecules across membranes c. Without the process of cellular respiration, there is no gaseous exchange and the cells, tissue and other organs die due to the lack of oxygen and by the accumulation of carbon dioxide within the cells and tissues. d. Cellular respiration is a type of passive cell transport. Molecules move from areas O of high concentration to areas of low concentration in order to decrease the concentration gradientIt is essential for the cells in plants and animals to have an adequate supply of oxygen. Explain what the oxygen is needed for in the cells? (Be as specific as possible.)
- Using the concepts of endo- and exo-cytosis explain the origin of the mitochondria. Include a drawingThe cardiovascular, respiratory, and gastrointestinal systems all work together to ensure that cells of the human body are able to carry out vital reactions, including aerobic respiration and protein synthesis. Question. Write a short account to explain how each of these three systems ensures that cells receive the required raw ingredients needed for such cellular reactions and how two of the systems contribute to the removal of the waste products created. Completion Note: (All three systems must be considered, and should include specific detail such as the role of named enzymes in the gastrointestinal tract and named biomolecules transported to and from cells. It is also important to briefly outline why body cells need to carry out aerobic respiration and protein synthesis.)Explain how cancer cell metabolism is different from normal cell metabolism. Describe how PET scans take advantage of this difference in metabolism to distinguish cancer cells from normal cells

A three-carbon molecule that is a final product of glycolysis 4. The final product(s) of anaerobic fermentation in animals and bacteria.
- Describe the process of cellular respiration. What are the products and reactants? How does cellular respiration relate to your everyday life? Are there any practical applications for having a knowledge of how cellular respiration works? (side note that has nothing to do with these questions: I had asked a previous question and it has been saying an expert is reviewing. but 13 hours has passed and i havent gotten my assignment done already can you tell anyone thats working within the same company as you to get it done already? i have to turn it in by 6am today. its 4am here. please and thank you)A segment of cell's collection of biochemical pathways is shown below. P is a product of one series of these reactions. It is also a regulatory molecule. Look at the pathway below and indicate the position(s) at which M is most likely to act as a feedback inhibitor when its concentration gets too high. 1 2 3 4 5 A----->B -----> C----->E----->J------>M----->P----->X----->ZCells use two ways of storing potential energy: 1) as concetration gradients and 2) in molecules. A) Explain how energy can be stored in these two forms and how it can be used to do the work. B) Propose an analogy that can explain each these forms of energy storage using everyday items.
