Try the two links below for labeled diagrams of ATP. The link for ADP has no labels, but you can recognize the components after looking at the ATP images.
The induction in Otto cycle is shown in the diagram at lower portion below atmospheric pressure(ATP) 0 to 1(from end of exhaust and starting of compression) the suction starts from ATP and then below ATP then to ATP due to the suction offered by piston from stored energy of fly wheel(ref.actual Otto cycle)
The protein looks like a dumb bell with two with two ends and the rod you mentioned is in the center. The entire unit rotates around with the "rod' embedded in the membrane. This helps to speed up the production of ATP from ADP. See the link below with a moving diagram:
ATP - adenosine triphosphate
The old ATP tally differs from the new ATP tally by about 2 ATP.
NADPH and ATP
ATP is known as Adenosine TriPhosphate. Hence the abbreviation ATP. ATP is produced by the ribosome in a cell. ATP is energy for the cell.
adp+p(i)--->atp ADP +P ---> ATP
1 ATP is used to begin.Also another ATP is used in glycolisis.
Glycolysis produces 4 ATP but uses 2 ATP to start the process.
ATP is a product.Respiration is a process.Respiration produces ATP.
