Q.In the prokaryotes ................. molecules of ATP are formed per molecule of glucose oxidised.

Step 1. Recall the chapter's own ATP balance sheet. Table 13.3 works out a net gain of 38 ATP per glucose molecule fully oxidised by aerobic respiration - a figure this chapter also applies to eukaryotes (matching Exercise 1B's answer).

Step 2. Consider what differs for prokaryotes. Prokaryotes have no mitochondria - their entire respiratory chain runs on the plasma membrane and in the cytosol, so there is no separate mitochondrial membrane for glycolytic NADH to be shuttled across. Since this chapter's own accounting already counts every NADH+H+ (including the two produced by glycolysis in the cytoplasm) at 3 ATP each, with n …

Applying Table 13.3's own net-ATP figure (38) to prokaryotic respiration, since prokaryotes lack a mitochondrial membrane and this b …

• Quoting 36 ATP, a figure used by some other textbooks specifically for EUKARYOTES to account for a 2-ATP shuttle cost when moving glycolytic NADH into the mitochondrion - a distinction this chapter's own Table 13.3 does not draw, since it already computes eukaryotic net ATP as 38. …
