Fermentation Lab: Conclusion & Evaluation of the Effect of Type of Carbohydrate on Amount of CO2 Produced IB Biology/Topic: 3.7 05 February 2013 Question: Which type of carbohydrate‚ glucose‚ sucrose‚ or starch‚ will produce the greatest amount of fermentation over the class period? Why? Hypothesis: If the carbohydrate starch is added to the set up of yeast‚ then it will create the greatest amount of fermentation because starch is a polysaccharides

Carbohydrates General molecular formula Cn(H2O)n Appeared to be hydrates of carbon. not all carbohydrates have this empirical formula: deoxysugars‚ aminosugars Carbohydrate - polyhydroxy aldehyde‚ ketones. General characteristics Most carbohydrates are found naturally in bound form rather than as simple sugars Polysaccharides (starch‚ cellulose‚ inulin‚ gums) Glycoproteins and proteoglycans (hormones‚ blood group substances‚ antibodies) Glycolipids

eat a variety of foods from each of these groups‚ your body will receive all the nutrients and vitamins it needs to function. The five food groups are: 1. Bread‚ cereals and potatoes: ( carbohydrate‚ calcium and iron‚ B vitamins and dietary fibre) - Carbohydrate is needed to provide energy. Starchy carbohydrates are broken down and converted to glucose which is either stored as glycogen in the liver and muscles or is circulated in the bloodstream where it can enter cells and be used as energy. -

to these substances to give them a better taste. 6. Which food substances contained starch? Are these results expected? Explain. The potato contained starch. This was expected because I know a medium sized potato can contain up to 30 grams of carbohydrates. 7. Which substances contained protein? Are these results expected or not? Explain. The chicken and the eggs contained protein. This was expected

management diet‚ which is based on specialized shakes‚ soups‚ bars and muesli. The diet is advertised as low GI and low carbohydrate. The diet is designed to induce the individual into a state of ketosis‚ ‘Ketone bodies are produced mainly in the mitochondria of liver cells. Its synthesis occurs in response to low glucose levels in the blood‚ and after exhaustion of cellular carbohydrate stores‚ such as glycogen. The production of ketone bodies is then initiated to make available energy that is stored
