The enzyme responsible for atp production?

The enzyme is synthase

Well, it would be easier if I had choices, but here's what I found:

"Chemical engineers also develop solutions to environmental problems, such as pollution control and remediation. And yes, they process chemicals, which are used to make or improve just about everything you see around you.""Another source mentioned that they use chemistry to solve everyday problems. They also help make [them] as environmentally safe as possible, and eliminate as much waste as they can."

Hope this helps! :)
