- In order for the reaction rate to rise the activation energy should be Select one: O O O O a. decreased b. increased c. decreased or increased d. not changed Riboflavin gives rise to cofactors:Define the following terms:a. reactive oxygen speciesb. antioxidantc. oxidative stressd. respiratory burste. reactive nitrogen speciesWhat is not an example of a reactive oxygen species (ROS)? 1. superoxide 2. hydroxyl radical 3. hydrogen peroxide 4. glutathione
- The enzyme catalase is found in beef liver. This enzyme is responsible for the rapid breakdown of hydrogen peroxide to water and oxygen. When the catalase in the liver works properly, the speedy release of O2 and H2O will cause a foaming effect. When the enzyme activity increases, there is more foaming, and when the enzyme activity decreases, there is less foaming. If the enzyme becomes denatured, there will be no foaming.Which protein of the following has a catalytic role? Antibody Enzyme Collagen HormoneWhich of the following is NOT a physiological role of phosphorus? Select one: a. Required for ossification of bones during embryonic development b.
