Practice short answer questions for test 1, BIO 101N, Spring 09 IMPORTANT! Try to answer questions in the space provided (emphasis on try, so if you can’t or don’t want to, that’s fine). This will force you to synthesize the material and write a concise to-the-point answer, which will be easier to remember (and easier for me to grade!).

Contains enzymes that detoxify drugs. E. Contains attached ribosomes and participates in protein processing. F. These organelles are responsible for the digestion of complex chemicals (such as proteins) in animal cells. 4. Briefly explain why ice floats on top of water. 5. Outline the organelles that are involved in the secretion of a protein such as human insulin. You MUST write your outline in the order in which the protein travels through the cell organelles. Next to each organelle, write what is happening to the protein. • ; contains the information required to build the protein. • RNA; • ; protein is synthesized. • ; • ; • plasma membrane; Page 2
