Which part of the F1Fo ATP synthase is responsible for ATP production? the c subunits of the Fo mobile component the a subunit of the Fo static component the gamma subunit of the F1 mobile component the beta subunits of the F1 static component

Introduction: It is an enzyme that generates ATP (adenosine triphosphate) directly during cellular respiration. ATP is the significant energy-rich molecule used by cells. The enzyme ATP synthase produces ATP from ADP (adenosine diphosphate) and inorganic phosphate (Pi) via the process of oxidative phosphorylation. In this process, the enzyme oxidizes nutrients for the formation of ATP. ATP synthase is present in all forms of life and powers all cellular processes. Answer: The enzyme ATP synthase is also referred to as F1F0 ATPases as these molecules can catalyze the hydrolysis or synthesis of ATP. In a eukaryotic organism, they are present on the inner mitochondrial membrane, while in archaea and bacteria, it is located on the inner surface of the cell membrane. The ATP synthase possesses two portions, one embedded inside the cell membrane, referred to as F0. The hydrogen ions that flow across the membrane supplies power to F0. F1 is the portion located in the archaeal or bacterial cell. The F0 has structural similarities with the DNA helicase enzyme, while the F1 portion has similarities with the H+ motor that causes the flagellar movement, as observed in some bacteria. The movement of the protons down their concentration gradient via the F0 subunit makes up the gamma subunit, and the F0 subunit rotates. Conformational alteration occurs in the beta subunit when the gamma rotates quickly inside F1. This allows the entry of molecules like inorganic phosphate and ADP into the catalytic site. Another alteration in the conformational area joins the inorganic phosphate with the ADP loosely at the catalytic site. The ATP molecule is synthesized when there is a conformational change from beta-DP to beta-TP. ATP is released when the conformation is altered from beta-TP to beta-E. Therefore, as per the above explanation, the fourth option that mentions 'the beta subunits of the F1 static component' is correct, and the remaining options are incorrect.
