The Beginning:
Turns out asking your grandma how to make bread actually pays off. We were assigned this project in our honors biology class, and we immediately started to research. The project was to make bread, and to find out what ingredient makes the fluffiest, most risen bread.
Background: Cellular Respiration & CO2 Cycle
When making bread you can see cellular respiration in action, but what is cellular respiration? Cellular respiration is the process of the cell turing glucose into a usable energy. It can be expressed in the chemical equation below:

Hello!! Are you interested in a scrumptious bread recipe filled with lots of flavor?
Introduction:
My friends and I wanted to test some new recipes, so we decided to delve into some baking. Lilly told me about her grandmother’s legendary whole wheat chocolate chip bread. Then my other friend Emma suggested we make our own bread recipe.

In our biology class, we are making bread. Considering none of us are true “bakers” and have never attempted to make bread from scratch before, we weren’t too sure about how our product would turn out. The main point of this bread lab was for us to better understand how fermentation, photosynthesis and cellular respiration takes place when making bread.
Procedure:
First, in a ziploc baggie mix together ¼ teaspoon yeast, and ¼ cup of flour and, 1 tbsp of sugar and ½ tsp of salt

Preparing for the experiment: Balloon lab
In order to begin to understand the process of how yeast interacts with different amounts of sugar we completed a alcohol fermentation lab. To set up the lab we added different amounts of sugar to each test tube, it was as follows:

RecipeFirst we added ¼ cup of flour
We also added a bit of flour to the dough as we were kneading it to make it not stick to our hands as much and so the dough would stick together better
We then added 4 tablespoons of heated water
We also added ¼ teaspoon of yeast
Then we added ½ teaspoon of sugar
We also added ⅛ teaspoon of salt
Cellular Respiration
O2 + C6H12O6 -> CO2 + ATP + H2O
Happens in the Mitochondria
This makes CO2 which makes the bread rise
The wheat is doing photosynthesis then that glucose goes into the the mitochondria where it does cellular respiration
Anaerobic Respiration vs Aerobic Respiration
Yeast does alcoholic fermentation which is a form of anaerobic respiration and humans do both in Lactic acid fermentation and also does aerobic respiration.
