Here are the notes I made for an experiment I was doing (I didn't put it here as it is too long)

(please ignore the numbers at the end of the pdf file)

The graph looks like this:

enter image description here

As you see on the graph, the numbers are the same as the ones below

1. The effect running out of glucose has on the yeast growth Our yeast increased in number by dividing rapidly. They use glucose to respire and release energy. They need energy to grow.

2. Why the yeast starts to grow again The yeast starts to decrease in volume when they ran out of glucose.

3. Describing patterns in graphs The yeast breaks down the starch to glucose

The problem is, why did the yeast rise at the end, I forgot?

Thanks in advance

I just would like to say that the teacher never talked about the production of Co2 –  Tim Timmy Nov 3 '13 at 20:36
