Apparatus used to investigate whether oxygen is used during aerobic respiration Questions 1. Identify the experiment and the control. Explain your answer. (2) 2. What precaution do you need to take before setting up the experiment? (2) 3. What is the function of the soda lime in the test tube? Explain why this is necessary. • As the beetle respires and uses the gas in the test tube what happens: a) to the volume of the gas in the test tube? (1) b) to the coloured water in the rubber tubing? Why is the test tube kept in water at a constant temperature? (2) What temperature should the water be? Give a reason for your answer. (2) Why is oxygen necessary during aerobic respiration? (2)

The dna in a cell’s nucleus encodes proteins that are eventually targeted to every membrane and compartment in the cell, as well as proteins that are targeted for secretion from the cell. for example, consider these two proteins: phosphofructokinase (pfk) is an enzyme that functions in the cytoplasm during glycolysis. insulin, a protein that regulates blood sugar levels, is secreted from specialized pancreatic cells. assume that you can track the cellular locations of these two proteins from the time that translation is complete until the proteins reach their final destinations.for each protein, identify its targeting pathway: the sequence of cellular locations in which the protein is found from when translation is complete until it reaches its final (functional) destination. (note that if an organelle is listed in a pathway, the location implied is inside the organelle, not in the membrane that surrounds the organelle.)
