Hello, I'm EricEnfermeroMobile. An edit that you recently made to Cellular respiration seemed to be a test and has been removed. If you want more practice editing, please use the sandbox. If you think I made a mistake, or if you have any questions, you can leave me a message on my talk page. Thanks! EricEnfermeroMobile (talk) 23:22, 4 October 2013 (UTC)
