Make connections the proton pump shown in figure 7.17 is depicted as a simplified oval purple shape, but it is, in fact, an atp synthase (see figure 9.14). compare the processes shown in the two figures, and say whether they are involved in active or passive transport (see concepts 7.3 and 7.4).

Part a - which gene to compare? in this exercise, you will use the cytochrome c oxidase i (coi) gene to investigate relationships among salmon species. (this gene encodes a protein that functions in the mitochondrial electron transport chain.) you will compare the coi gene sequences from your salmon test samples to the standard sequences for each salmon species. in order for the coi gene to be useful for distinguishing among the different salmon species, which three statements must be true?
