Today in a biology lecture about plasma membranes and functions of proteins, we learned about channel and enzymatic proteins along other kinds of proteins. ATP synthase is considered an enzyme that synthesizes ATP, but it also creates a channel for H+ ions to pass through into a lower concentration area.
My question is could ATP synthase be considered a channel protein as well as enzymatic protein? Or no since the ion channeling is part of the enzymatic reaction? Also are there more examples were some proteins could have more than one kind of protein to them?
