Part 2: PASTEUR EFFECT - FERMENTATION VS. RESPIRATION Louis Pasteur, the great French biochemist, studied the metabolism of yeast - a facultative anaerobe. He observed that yeast consumed sugar much faster under anaerobic conditions than when oxygen was available. This is called the Pasteur Effect. To understand why this happens, answer the questions below: 1. How many glucose molecules do a yeast cell need to produce 30 ATPS by aerobic respiration? (2 points) A. 30 B.2 c. 1 D. Depends on the type of yeast E. Yeast cannot do aerobic respiration because they lack mitochondria 2. How many glucose molecules do a yeast cell need to produce 30 ATPS (the same number of ATPs as in question 1) by fermentation? (2 points) A. 30 B. 15 c.2 D. 1 E. Depends on the type of fermentation
