BIS 2A MIDTERM 2 2023/2024 On early Earth, the first things that looked like they might be classified as living organisms used iron sulfur clusters as catalysts. If these "naked" iron sulfur clusters can catalyze reactions, why do our cells instead use proteins carrying iron sulfur clusters as catalysts? a. To decrease substrate specificity b. To increase substrate specificity c. To prevent spontaneous oxidation of the iron in the cluster d. a and c e. b and c - CORRECT ANSWER-e. ...
