As we can see on the graph we can tell how clearly glucose has highest respiration rate of 455 ppm/min. Sucrose is second with 391 ppm/min‚ then fructose with 231 ppm/min and lastly lactose with 92 ppm/min. We can see a clear trend‚ that glucose had the highest rates and that lactose was the lowest‚ so we see a clear downwards sloping trend‚ which was also expected. This suggests that yeast respires best with glucose instead of sucrose fructose or lactose. To explain this process‚ we must first understand

process will be examined‚ by measuring the pH of reaction‚ lower pH means more CO2 production. The first factor being measured is the type of sugar used in the fermentation of yeast. The types of sugar being used in the experiment is glucose‚ sucrose‚ and lactose. Glucose is a monosaccharide and is used in the first step of glycolysis in order to help create pyruvates‚ which are then used to create ethanol as long as there is no mitochondria or oxygen present. Sucrose is a disaccharide‚ commonly referred

Hannah was diagnosed with Type 1 Diabetes Mellitus. Type 1 Diabetes Mellitus is chronic disease in which there is a high level of sugar (glucose) in the blood. Without insulin‚ the glucose goes to bloodstream and instead of going in the cells which causes Hyperglycemia. Then the body can’t use the glucose which than results in Type 1 Diabetes. The exact reason for Type 1 Diabetes is unknown. Most usually auto immune disorder. With this disorder the immune system attacks the good healthy body tissue

iLab #2 Carbohydrate Tests INTRODUCTION - For this experiment we will be testing four different bacteria with four different tests‚ using glucose‚ lactose‚ and sucrose. Hopefully we will use the information from those test to be able to identify the organisms in each of the samples from the case studies. We will use the results from the four different tests along with the information of how different bacteria react to match up to the case

we have to break it down into its two ingredients that it is made up of‚ glucose and fructose. Sugar‚ or its natural form‚ sucrose‚ is a carbohydrate‚ which makes it an energy substance. It is also known‚ as sucrose is a sweet crystalline substance obtained from various plants‚ especially sugar cane and sugar beef. It is used a sweetener in foods to make them taste better‚ and is made up off glucose and fructose. Glucose‚ called a simple sugar‚ is a carbohydrate‚ which makes it a pure energy

turning the corrective measures off. Homeostasis uses the principle of negative feedback in order to maintain a constant internal environment. There are a number of different examples of negative feedback such as thermoregulation‚ regulation of blood glucose and the regulation of water potential. The control of the heartbeat can also use negative feedback mechanisms. In mammals a constant body temperature is maintained using the part of the brain called the hypothalamus‚ this detects information from

The structural features of carbohydrates account for the fact that a wide variety of polysaccharides exist is pentoses and hexoses. The examples of pentose are ribose‚ deoxyribose‚ ribulose and xylulose. The examples of hexose are glucose which is found in fruits‚ fructose which is found in milk and galactose which is found in honey. Both pentoses and hexoses are mostly found in monosaccharides. They are the most simplest sugar which cannot be futher hydrolysed into smaller units. They contain

If you exercise regularly or if you are an athlete in training‚ you are trying to make your muscles work better. You want to be stronger if you are a weightlifter‚ you want to be able to throw a blistering fast ball if you are a baseball pitcher or you want to be able to finish strong at the end of a 26-mile race if you are a marathon runner. Adequate nutrition is a key component of sports performance. The greater the demands for increased performance both in training and competition‚ the higher
