Please check to see thatall the pages are present before you begin. Use a #2 pencil and bubble in all answers. Your score will beposted on the UIC Blackboard site as soon as they are in. No kidding. Good Luck! Matching - Use the key below to select the best answers for questions 1 - 8. Here’s a hint - mostpeople get really thrown by this section, so take the rest of the exam and come back to it.I. Glycolysis VI. Alcohol FermentationII. Oxidation of Pyruvate VII.
