activity
would take place with 60% sucrose concentration. Since yeast fermentation
requires sucrose and water, aproximately equal proportions of both would yield
to the most respiratory activity.

Once the sucrose concentration was serially cut to the desired level,
the experimenter added 5 ml of yeast suspension to each one of the ten test
tubes.

Then, ten small test tubes were placed invertedly into each one of the
large test tubes, making sure no air bubbles remained within the small tibes.
The test tubes were left 24 hours, allowing for fermentation to take
place. But, no respiratory activity was detected.
In previous experimentation, it was found that yeast fermentation did
take place in different molasses concentrations. Since, molasses contains
large quantities of sucrose, it was assumed that different concentrations of
pure sucrose would yield similar results, when mixed with yeast. However, this
was not the case.

The probable explanation is that in order ...
