Question
Chapter 6, Problem 80TQ
Summary Introduction
To review:
The following Km values for the enzyme ADH1 in Saccharomyces cerevisiae for ethanol and acetaldehyde are given. The possible reaso, nased on Km values, that explains the role of ADH1 enzyme in the ethanol
| Km (ethanol) | Km (acetaldehyde) | |
| ADH1 | 20,000 µM | 1500 µM |
Introduction:
The organism Saccharomyces cerevisiae produces ethanol by utilizing glucose moleculesirrespective of the presence or absence of oxygen. The enzyme, alcohol dehydrogenase (ADH) catalyzes this reaction. Km is the equilibrium constant, which signifies the affinity of an enzyme for its substrate. The value of Km of a particular enzyme may change according to the substrate.

What is the importance of glutamic acid in the metabolism of nitrogen from amino acids? (we know therole; it’s used to remove the nitrogen from amino acids so that the remaining carbon skeleton can bebroken down by the “usual” pathways, but what is the important, unique role that only glutamicacid/glutamate can do?)
