(I just finished Bio chemistry in my class. Ill tell you what I know about enzymes and hope itll help you, but if it doesnt, could you list the awnsers?)
-Enzymes are protiens -Enzymes speed up the chemical process of breaking down material (like food) -All enzymes have an 'Active sight' that attatch the substrate -Active sight and substrate fit like a puzzle peice (can slightly alter to perfectly fit)
Animals get energy from food. Plant related food takes the sun to grow, and other prey may get energy from plants which uses the sun to grow. If you have any questions, don't hesitate to ask!
