The effect of sugar on yeast
Показать описание
I started with 3 cups of yeast: one had 0 grams of sugar, the second had 10 grams of sugar, and the last had 20 grams of sugar.
I added 250 mL of warm water to each cup and stirred, and left my camera to record them.
What's happening? As the yeast use energy, they release carbon dioxide gas. In more technical terms, they are performing cellular respiration to produce energy so they can grow, and a byproduct of cellular respiration is carbon dioxide. This is similar to how you breathe out carbon dioxide.
This means we can use carbon dioxide production as a proxy (measurement) for how much each cup of yeast is growing.
Which cup of yeast will grow the most and why?
