Provide a balanced equation (substrates, products, cofactors) and the name of the enzyme that catalyzes the last reaction of glucose metabolism in red blood cells. Structures are NOT required. (4 points) b. Why do red blood cells need to catalyze this last reaction? (2 points) 2. One of the most common genetic deficiencies in humans results in a hemolytic anemia induced by fava beans and anti-malarial compounds such as primaquine. a. Name the enzyme lacking in this deficiency. (2 points) b. Provide a balanced equation for the reaction catalyzed by this enzyme (substrates, products, cofactors). Provide names and structures for substrates and products, name only for cofactors. (4 points) c. Which of the products of this reaction is necessary to protect red blood cells from hemolytic anemia? (2 points)
