A researcher has isolated an organic, water-soluble chemical from roses. After performing in-vivo tests, the scientist determines that the chemical supplies no energy for cells, but protects cell membranes from being damaged by certain environmental factors. Based on this information, the researcher may have discovered a (an) A. antioxidant. B. amino acid. C. precursor. D. autoanalyzing agent. Bloom's Level: 3.

11. Which of the following vitamins have antioxidant activity? A. E B. B-6 C. K D. D Bloom's Level: 1. Remember Learning Outcome: 8.02.02 Discuss major functions of each fat-soluble vitamin. Section: 8.02 Topic: Nutrient functions Topic: Vitamins 12. A medical researcher is investigating the chemical and physical properties of substance that she isolated from the surface of charcoal-grilled meat. When the scientist mixes a small amount of the substance with living human cells, the chemical causes the rapid breakdown of the cells' plasma membranes. She is able to prevent this reaction by adding vitamin C to the mixture of the substance chemical and cells. Based on this information, the scientist has A. isolated a potential treatment for cancer in charcoal-grilled meat. B. discovered that vitamin C is has pro-oxidant activity in-vivo experiments. C. conducted an in-vitro experiment under poorly controlled conditions. D. determined that the chemical isolated from charcoal-grilled meat is an oxidant. Bloom's Level: 3.
