Anaerobic Respiration - Fermentation Test

Welcome to the Electronic Frontier Classroom of the 21st Century. There are many fermentation pathways, and they differ in terms of the enzymes that are used and the compounds that are made from pyruvic acid. You will be tested on production of lactic acid and ethyl alcohol. As "fill-in" type questions appear in this test, please enter your answer(s) using all lower case letters. Unless a question has specific directions printed for you to follow. The test settings for your learning pleasure are unlimited number of attempts with a total of 25 questions for each randomized test. I wish good luck on learning about anaerobic respiration and fermentation!.
