ATP synthase (EC 3.6.3.14) is an important enzyme that provides energy for the cell to use through the synthesis of adenosine triphosphate (ATP). ATP is the most commonly used "energy currency" of cells from most organisms. It is formed from adenosine diphosphate (ADP) and inorganic phosphate (Pi)‚ and needs energy. The overall reaction sequence is: ADP + Pi → ATP‚ where ADP and Pi are joined together by ATPsynthase Energy is often released in the form of protium or H+‚ moving down an electrochemical

Subject Title : Biology Program : Diploma Program (IB) School Year : 2014-2016 Instructor : Jeffrey Joseph Y. Araula‚ MMM NATURE OF THE SUBJECT Biology is the study of life. The first organisms appeared on the planet over 3 billion years ago and‚ through reproduction and natural selection‚ have given rise to the 8 million or so different species alive today. Estimates vary‚ but over the course of evolution 4 billion species could have been produced. Most of these flourished for a
