ATP synthase is an enzyme used for the synthesis of ATP through aerobic respiration. It is consist of two parts-Fo and F1. The Fo is bound to inner mitochondrial membrane whereas the F1 is present in the matrix. FO causes rotation of F1. Fo F1 together forms the pathway for protons movement across the membrane. F1 is composed of three subunits of α and β, and one subunit of γ, δ and ε. F1 consist of water-soluble part that can hydrolyze ATP. While, Fo is made of c-ring and subunits a, two b, F6. FO consist of mainly hydrophobic regions.FO region of ATP synthase is embedded in the mitochondrial membrane and forms a proton pore. Fo is consist of a, b and c subunits. Subunit a connects b to the c ring. Subunit b makes up a stalk connecting to F1 which prevents the rotation of αβ hexamer. Six c subunits make up the rotor ring. F1 is hydrophilic region and it protrudes into the mitochondrial matrix. Subunits α and β forms a hexamer with 6 binding sites. γ, δ, and ε subunits of F1 forms the part of a rotational motor. γ subunit allows β to go through conformational changes which allows ADP to bound and release of synthesized ATP. The correct option is (c) 1) stator, 2) rotor, 3) head piece Explanation: As we can see in the image the a subunit of Fo is present in the stator. The stator stalk (a subunit of Fo) connects the b to c ring region. The rotor shaft is made of the γ-subunit. Ant the beta subunit is present in the head-piece of F1. Conclusion: Hence, the correct option is (c) "1) stator, 2) rotor, 3) head piece"
