Yeast on Atkins: A Study of Protein Diets on Yeast Growth By Ana Gordon-Loebl

Introduction The average person in the U.S. gets 50% of calories from carbs The average person in the U.S. gets 50% of calories from carbs On the Atkins diet, only 10% of calories come from carbs On the Atkins diet, only 10% of calories come from carbs The body’s response to low carb intake is called ketosis. The body’s response to low carb intake is called ketosis. People in ketosis burn stored fat for energy. This takes more energy than burning carbs, so more protein is needed to burn the same # of calories People in ketosis burn stored fat for energy. This takes more energy than burning carbs, so more protein is needed to burn the same # of calories

Introduction, Continued Digestion in yeast cells is comparable to digestion in human cells. Digestion in yeast cells is comparable to digestion in human cells. Humans and yeast are very similar on a cellular level. Humans and yeast are very similar on a cellular level. Just like human cells, each yeast cells contains a cytoplasmic membrane, cytoplasm, a nucleus, vacuoles, and mitochondria. Just like human cells, each yeast cells contains a cytoplasmic membrane, cytoplasm, a nucleus, vacuoles, and mitochondria. During the growth phases, yeast breaks simple sugars down to release energy and uses nutrients from a nitrogen source (i.e. amino acids).

Hypothesis The yeast grown in higher concentrations of carbohydrates will grow more quickly than the yeast grown with higher concentrations of protein. The yeast grown in higher concentrations of carbohydrates will grow more quickly than the yeast grown with higher concentrations of protein. After 5 days, there will be more colonies of yeast in the trays with carbohydrates than in t he trays with protein. After 5 days, there will be more colonies of yeast in the trays with carbohydrates than in t he trays with protein. I hypothesize that there will be a direct relationship between the concentration of carbohydrates in the tray and the number of yeast colonies that will grow in the tray. I hypothesize that there will be a direct relationship between the concentration of carbohydrates in the tray and the number of yeast colonies that will grow in the tray.

Methods Five trays of gelatin were prepared in muffin tins. Five trays of gelatin were prepared in muffin tins. Each tray held a different concentration of proteins and carbohydrates. Each tray held a different concentration of proteins and carbohydrates. Yeast was spread equally over each of the trays and was left to grow for 5 days. Yeast was spread equally over each of the trays and was left to grow for 5 days. After 5 days, the yeast colonies were counted and recorded. After 5 days, the yeast colonies were counted and recorded. These steps were repeated 4 times in order to collect 4 different sets of data. These steps were repeated 4 times in order to collect 4 different sets of data.

Methods, continued I spread the yeast (dissolved in warm water) in the tray in the above way) I used muffin tins w/ aluminum cupcake inserts, Baker’s yeast, and amino acids in the form of protein pills

Results, continued The graph shows a direct relationship between the concentration of carbs in the tray and the number of colonies that grew in each tray. The graph shows a direct relationship between the concentration of carbs in the tray and the number of colonies that grew in each tray. As the concentration of carbohydrates decreased, so did the number of colonies As the concentration of carbohydrates decreased, so did the number of colonies In addition, the graph shows an indirect relationship between the concentration of protein and the number of colonies (as the concentration of protein increased, the number of colonies decreased). In addition, the graph shows an indirect relationship between the concentration of protein and the number of colonies (as the concentration of protein increased, the number of colonies decreased). Both trials were contaminated with mold, so the results may not be 100% accurate Both trials were contaminated with mold, so the results may not be 100% accurate

Conclusion The hypothesis that there is a direct relationship between the concentration of carbohydrates in the tray and the number of yeast colonies in grown in the tray was proven. The hypothesis that there is a direct relationship between the concentration of carbohydrates in the tray and the number of yeast colonies in grown in the tray was proven. From the results of the experiment, it can be concluded that the Atkins diet is effective in slowing the growth of yeast colonies. From the results of the experiment, it can be concluded that the Atkins diet is effective in slowing the growth of yeast colonies. Further, one can take the results and infer that the Atkins diet would therefore slow the growth of humans as well.

However, more trials will have to be done before concrete conclusions are made because the mold may have influenced the results.

Future Studies In order to test the effectiveness of the Atkins diet compared to low-fat diets, yeast could be put on diets with varying concentrations of carbohydrates. In order to test the effectiveness of the Atkins diet compared to low-fat diets, yeast could be put on diets with varying concentrations of carbohydrates. In order to test the effects of the Atkins diet on the body’s immune system, yeast can be grown with varying degrees of the diet and then be put under stress (i.e. soaked in detergent). The ability of the yeast to recover from this stress could provide insight into the healthiness of the Atkins diet.
