Succinate dehydrogenase is an iron-containing flavoprotein enzyme that catalyzes the dehydrogenation of succinic acid to fumaric acid. This reaction is a key step in the Krebs cycle, a central metabolic pathway for energy production in aerobic organisms. The enzyme is widely distributed in animal tissues, bacteria, and yeast. It plays a role in the respiratory chain, transferring reducing equivalents from substrates to molecular oxygen, which ultimately leads to the synthesis of ATP, the cell's primary energy currency.12
