People who are infected with HIV do not get sick immediately. It can take the body months to attempt to fight off the virus and for a patient to test HIV-positive. So, paradoxically, the period when an HIV-positive person is most infectious coincides with the period he or she is least likely to know their status.
The ATP synthase of mitochondria and chloroplasts is an anabolic enzyme that harnesses the energy of a transmembrane proton gradient as an energy source for adding an inorganic phosphate group to a molecule of adenosine diphosphate (ADP) to form a molecule of adenosine triphosphate (ATP).
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 (P i), and needs energy.The overall reaction sequence is: ADP + P i â ATP, where ADP and P i are joined together by ATP synthase.he same process takes place in the mitochondria, where ATP synthase is located in the inner mitochondrial membrane (so that F 1 -part sticks into mitochondrial matrix, where ATP synthesis takes place).
