Which is more complex? Cellular respiration or fermentation?

Cellular Respiration is more complex

Explanation:

hope this helps  

Well I take it that Cellular respiration is more complex because of the fact that fermentation is actually easier than that of the Cellular process and when I say Cellular is more complex I mean it probably takes more time and has more different parts than fermentation.

And I hope I helped explained the best way I could!

Explanation:

Fermentation is a simpler process that produces the products within a single step. ... While aerobic respiration and fermentation both produce energy, the products of the processes are in different forms. The products of aerobic respiration are carbon dioxide, water, and energy in the form of ATP.
