Now, reflect upon the components which make up the growth medium used to cultivate yeast. Whilst the growth medium was being made, the component which provides a source of energy for yeast was omitted. What component was left out? What effect will this have on the growth curve phases and the rate at which they occur, especially in regard to the 'Exponential Growth' phase of the yeast?

Step 1
Bacteria grow rapidly under a favorable environment where all the necessary conditions for its growth are present. When bacteria are grown in a closed system or batch culture where neither the food is added nor the waste is removed, bacteria grow in a predictable pattern and when it is plotted on a graph, a distinct curve known as bacterial growth curve is obtained.
