24. Where is the enzyme glucose-6-phosphatase located?
(A) cytosol
(B) endoplasmic reticulum
(C) mitochondria
(D) nucleus
(E) none of the above

25. Which of the following is the most distinguishing difference between a purine and a pyrimidine? (A) Purines are double ring structures while pyrimidines have a single ring. (B) Purines have nitrogens in the rings while pyrimidines do not. (C) Pyrimidines have nitrogens in the rings while purines do not. (D) Purines are found in RNA while pyrimidines are found in DNA. (E) Purines are found in DNA while pyrimidines are found in RNA.

26. Phospholipases break down fats by _____ (A) adding a phosphate group to them (B) reducing the double bonds to single bonds (C) hydrolyzing them (D) removing acetyl-CoA units (E) none of the above

27. Certain restriction enzymes produce cohesive (sticky) ends. This means that they _____(A) cut both DNA strands at the same base pair (B) cut in regions of high GC content, leaving ends that can form more hydrogen bonds than ends of high AT content (C) make a staggered double-strand cut, leaving ends with a few nucleotides of single-stranded DNA protruding (D) make ends that can anneal to cohesive ends generated by any other restriction enzyme (E) stick tightly to the ends of the DNA they have cut

28. All of the following are considered "weak" interactions in proteins, EXCEPT: (A) hydrogen bonds (B) hydrophobic interactions (C) ionic bonds (D) peptide bonds (E) van der Waals forces

29. The force that drives an ion through a membrane channel depends upon (A) the charge on the membrane (B) the difference in electrical potential across the membrane (C) the size of the channel (D) the size of the ion (E) the size of the membrane

30. Which of the following is a product of the activation of fatty acids? (A) CoA-SH (B) ADP (C) pyrophosphate (D) none of the above (E) all of the above

31. If you touch a hot stove and burn your hand, the pain isn't actually in your hand-it's in your head. What evidence can you provide to substantiate this claim? (A) A reflex arc allows the quick response between the hand and the brain; no interpretation occurs. (B) Sensory neurons and interneurons carry the heat sensation to the brain where it is interpreted as painful. (C) Motor neurons pull your hand away from the flame, signaling pain to the brain. (D) Interneurons form connections directly from the burned receptor molecules to the brain. (E) All of the above.

32. Oral rehydration solutions that contain both salt and glucose are highly effective in treating severe dehydration caused by diarrhea and vomiting. However, glucose or salt alone are not effective. Why? (A) Glucose without sodium is broken down too quickly in the mouth by saliva. (B) Water alone rushes through the digestive tract too quickly to be absorbed by the body tissues. (C) Sodium transport and glucose transport are coupled in the small intestine so that glucose accelerates absorption of salt and water. (D) ATP is required to transport sodium unless glucose is available for cotransport. (E) None of the above.

33. How does the digestion and absorption of fat differ from that of carbohydrates? (A) Processing of fat does not require any digestive enzymes, whereas the processing of carbohydrates does. (B) Fat absorption occurs in the stomach, whereas carbohydrates are absorbed from the small intestine. (C) Carbohydrates need to be emulsified before they can be digested, whereas fats do not. (D) Most absorbed fat enters the lymphatic system, whereas carbohydrates directly enter the blood. (E) Fat must be partially digested by bacteria in the large intestine before it can be absorbed, which is not the case for carbohydrates.

34. Which of the following physiological responses to hemorrhage is correctly described? (A) The increase in cardiac output due to hemorrhage results in enhanced venous return, which compensates for the blood loss. (B) Hemorrhage causes a drop in blood pressure, and the baroreceptor reflex increases sympathetic activity, leading to vasoconstriction and increased heart rate to preserve blood pressure. (C) Blood volume expansion following hemorrhage is mediated by parasympathetic activation, which reduces vasoconstriction. (D) The physiological response to hemorrhage primarily involves vasodilation to improve blood flow to tissues affected by low blood volume. (E) Shock caused by hemorrhage results in complete cessation of blood flow to the brain, leading to immediate neuronal death.
