Answers must be in essay form (unless stated otherwise, example-graphing or creating data tables). Outline form is not acceptable. Labeled diagrams may be used to supplement discussion, but in no case will a diagram alone suffice. It is important that you read the question completely before you begin to write. Make notes on this paper to guide you through your essay. Once you begin to write continue to reference the question Write your answer on the lined pages that appear at the end of the question or on paper provided by your teacher (for practice you will use your own notebook paper, answer both questions). Staple this paper to the top of your essay, you may write on this paper, this is due today!! FRQ’s:The results below are measurements of cumulative oxygen consumption by germinating and dry seeds. Gas volume measurements were corrected for changes in temperature and pressure.Cumulative Oxygen Consumed (mL)Time (min) 0 10 20 30 4022C germinating seeds0.08.816.023.732.022C dry seeds0.00.20.10.00.110C germinating seeds0.02.96.29.412.510 C dry seeds0.00.00.20.10.2a. Using the graph paper provided, plot the results for the germinating seeds at 22C and at 10C.b. Calculate the rate of oxygen consumption for the germinating seeds at 22C using the time interval between 10 and 20 minutes.c. Account for the differences in oxygen consumption observed between:- germinating seeds at 22C and 10 C- germinating and dry seedsd. Describe the essential features of an experimental apparatus that could be used to measure oxygen consumption by a small organism. Explain why each of these features is necessary. A drawing may be used to supplement your answer.2. Energy is neither created nor destroyed, but it is changed from one form to another. Energy transfer is an important concept in cellular biology. In most eukaryotic cells, chemical bond energy in glucose is eventually converted to the chemical bond energy in ATP molecules in the process of aerobic cellular respiration.a. The majority of ATP molecules are produced in the process of oxidative phosphorylation. Describe this process including the names and locations of the structures involved and the formation of the electrochemical gradient.b. For 3 of the following situations, discuss the role of ATP in completing these examples of cellular work. - active transport-Glucose production in the dark reaction- cytokinesis in an animal cell- movement of a flagellum - Contraction of a muscle- control of the stages in mitosisEnergy transfer occurs in all cellular activities. For 3 of the following 5 processes involving energy transfer, explain how each functions in the cell and give an example. Explain how ATP is involved in each example you choose. cellular movementactive transportsynthesis of moleculeschemiosmosisfermentation ................
