An unwanted program running on a computer is called a: Pain Sickness Encryption Virus

The Nernst equation can be used to predict the membrane potential resulting from all permeable ions. intracellular ion concentrations. extracellular ion concentrations. the membrane potential resulting from permeability to a single ion.

Laboratory Review 5 I. How is "produces" represented in a chemical reaction? 2. Are the substrates in an enzymatic reaction reactants or products? 3. What is the name of the location on an enzyme where its substrate or substrates bind? 4. What cellular organelle contains catalase and is present in all plant and animal organs? S. What did measuringthe bubble column heights i al th experimental procedures indicate? 6. What purpose did the tube containing water and hydrogen peroxide serve in the catalase activity experimental procedure? 7. What word describes the loss of an enzyme's original shape and ability of its active site to function? 8. What happens to enzyme activity if the temperature increases slightly? 9. What did the negative control tube lack when the effect of enzyme concentration was studied? 10. If cells produce more catalase, will there be more or less water and oxygen produced from the breakdown of hydrogen peroxide by catalase? 11. What word describes the pH at which the speed of a reaction involving an enzyme 12. What do changes in pH (too low or too high) do to an enzyme that reduce its activity? 13. In the Experimental Procedure on the effect of pH on enzyme activity, which tube 14. Since enzymes are specific for certain substrates and often have similar names, what occurs best? contained water with an acidic pH? is the name of the enzyme used in tube 3 of the catalase activity experiment that facilitates the breakdown of sucrose? racilitates the breakdown of sucrose? Thought Questions 15. People with Crohn's disease may develop lactose intolerance caused by damage to their small intestine. These people may take a commercial product called Lactaid to prevent digestive upset when consuming dairy products What is in Lactaid about the specificity of enzymes for substrates in this lab. that helps these people avoid those symptoms? Explain how this relates to what you learned 16. High-grade fevers (in humans, 103°F or higher) are of concern, and medical care should be obtained. Explain why, based on your understanding of enzyme function. creatic amylase is a digestive enzyme that digests starch in the small intestine. Pancreatic amylase's optimum pH is slightly basic, which the presence of NaHČO, provides. Indicate which test tubes (1-3) would show digestion of starch following incubation. Explain why the others would not. Tube 1water, starch 17. Pan Tube 2 water, starch, pancreatic amylase, HCI Tube 3 water, starch, pancreatic amylase, NaHCO
