Below is the concentration of lactic acid in the blood of an athlete before, immediately after and one hour after completing a 400 m sprint.

Before race 25 M Immediately after race 197 M One hour after race 26 M

How can you explain the large increase in lactic acid (25 M versus 197 M) at the completion of the race?

b) You have identified a mutant yeast whose glycolytic pathway is shorter due to the presence of a new enzyme catalysing the following reaction:

Glyceraldehyde-3-Phosphate + H2O + NAD+ →

3-phosphoglycerate + NADH + H+

What would the effect of this mutation have on this mutant yeast’s ability to grow under i) aerobic, and ii) anaerobic conditions?
