Quiz Viruses %CODE1% Name: Viruses True/False Indicate whether the sentence or statement is true or false. TF 1. Although viruses do not consist of cells, biologists consider them to be living because they are capable of reproduction. TF 2. Some viruses have a membranous envelope surrounding the protein coat that helps them gain entry into host cells. TF 3. Viruses consist of RNA or DNA surrounded by a coat of protein. TF 4. Prions are the smallest known particles that are able to replicate. TF 5. A virus can only reproduce by controlling a cell. TF 6. Once a virus enters either a lytic or a lysogenic cycle, it cannot change to the opposite type of cycle. TF 7. Prophages and proviruses can both enter lytic cycles and destroy host cells. TF 8. People can contract the influenza virus more than once because the virus tends to mutate rapidly, avoiding the actions of the immune system. TF 9. Smallpox is caused by bacteria. TF 10. Chickenpox and shingles are caused by the same virus. Multiple Choice Identify the letter of the choice that best completes the statement or answers the question. ABCD 11.

Cell Respiration Quiz %CODE1% Cellular Respiration Quiz 1. Which of the following occurs in both photosynthesis and respiration? chemiosmosis glycolysis calvin cycle krebs cycle2. Which of the following statements is FALSE? glycolysis can occur with or without oxygen glycolysis occurs in the mitochondria glycolysis is the first step in both aerobic and anaerobic respiration glycolysis produces 2 ATP, 2 NADH, and 2 pyruvate 3. This process uses NADH and FADH2 to produce ATP oxidative phosphorylation fermentation glycolysis krebs cycle 4. This process begins with the production of Acetyl-CoA: chemiosmosis glycolysis fermentation krebs cycle 5. Cramps during exercise are caused by: alcohol fermentation glycolysis inhibition lactic acid fermentation chemiosmosis 6. Oxidative phosphorylation is also known as: chemiosmosis glycolysis fermentation electron transport chain 7. The final electron acceptor during oxidative phosphorylation is: oxygen water carbon dioxide ATP 8. Which of the following processes produces the most ATP? glycolysis oxidative phosphorylation fermentation krebs cycle 9. Which of the following is necessary for oxidative phosporylation to occur? ATP oxygen carbon dioxide lactic acid 10. Which of the following is the products of the Krebs cycle? ATP NADH FADH all of these Score = Correct answers: BACK
