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 enzyme is ATP synthase (sometimes referred to as "ATP synthetase").It catalyzes the synthesis of ATP from ADP and free inorganic phosphate. It is a remarkable enzyme, part of which spins round. In fact, ATP synthase has been called a molecular machine.To see an image, use the link below.
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 is the power source of almost all cells (There are only a few exceptions, but that is unnecessary information). It basically provides a cell or protein with energy by having its third phosphate group break off from the rest of the molecule- in doing so, massive amounts (relevant to the cell) is released, and this energy can be harvested for use. The result is ADP (Adenosine Di-Phosphate). The third phosphate group is broken off by Hydrolysis/Cleavage (The addition of water). The cycle then continues as ADP gains another Phosphate group through cellular respiration (Mitochondria). See link below for a two dimensional picture of ATP...
See "Related Links" for a link of the diagram.
So your body produces enzymes that break down pyruvate that will make 2ATP. This ATP will make you have seizures so make sure you see a doctor when you have ATP in your body. It could cause a fatal cranial contusion that will lead to a suicide. Vote Vermon Supreme for President
making ATP is endergonic. This is because after ATP hydrolysis to form ADP + P, we now are at a lower energy state and for ATP to be formed again it has to be fueled by catabolic pathways, eg respiration. this energy input allows ATP to be formed and thus we see that phosphorylation of ADP requires energy input (endergonic) to form ATP. Converting ATP into ADP and P itself is EXERGONIC.

I don't see the pictured lobe - or the label #1.
The platelet is such a simple cell fragment that there isn't much to the diagram. However, you can see many good diagrams of platelets on "Google images" Type in "platelet diagram" to the search box.
Unfortunately -since we cannot see the diagram you're asking about, we cannot help you !

2 ATP molecules are invested during glycolysis per each glucose molecule that is being metabolized. The first ATP molecule intervenes in the very first step, that is: from glucose to glucose 6-phosphate, catalyzed by a hexokinase, releasing an ADP molecule. The second ATP molecule is used in the third step: from fructose 6 phosphate to fructose 1,6-bisphosphate, catalyzed by a phosphofructokinase, and releasing also an ADP molecule.
Oxidation of G3P occurs by the removal of hydrogen atoms are picked up by NAD+, and NADH+H+ results. Later the NADH will pass on electrons to the electron transport chain. Oxidation of G3P and subsequent substrtes result in four high energy phosphate groups and these are used to synthesize four ATP. So basically substrate-level ATP synthesis is when an enzyme passes a high-energy phosphate to ADP and ATP results.

There are three phosphate groups in an ATP molecule. Go on to Google images and type in ATP or adenosine triphosphate. Look for a picture that contains chemical symbols and lines. Now, commonly on the right hand side you will see the bulk of the picture. On the left should be a line with P's and O's in the middle of it. The P's of course are the phosphates. The P closest to the bulk is called the alpha phosphate. then working out you have the beta phosphate and then the gamma phosphate. The symbols for these phosphates are the Greek letters for Alpha, Beta, and Gamma.
