stion 20 vet ered s out of g question Below is an image of how biotin is used in the reaction that converts pyruvate to oxaloacetate, an important metabolic reaction. The overall reaction is: Bicarbonate + ATP + pyruvate -> Oxaloacetate + ADP Which statement below is correct regarding biotin? xx-00 HO Bicarbonate HẠT NH Biotin Enz ATP Enol pyruvate ADP 2. NH Enz Carboxybiotin coo CIO CH₂ cooo Oxaloacetate HN NH Biotin O a. Biotin is a cofactor that serves as a reducing agent and is important for the generation of collagen O b. Biotin is a prosthetic group where the nitrogen serves as an electrophile and bicarbonate is a nucleophile O C Biotin is a cofactor that is covalently linked to the enzyme; the enzyme is a ligase
