Sucrose

added to sugar, the faster the production of CO2 is. Hypothesis: The rate of CO2 production will increase as the amount of glucose is put in the container. The rate of CO2 production will increase as the amount of sucrose is put in the container. Materials: Yeast Glucose Sucrose 2 small bottles Paper towels Weight scale Spoons…

A small amount of the bacteria was placed in to three diverse tubes, which had different carbohydrates. The bacteria produced acid and gas when placed in the tubes that had glucose, lactose and sucrose, however when placed in the tube of sucrose, acid was shown on the inside of the anaerobic part of the tube which caused no acid to be on the outside. The results given are typical for the E.coli carbohydrate fermentation. The last and final test that was done was a streak…

Introduction and Purpose: Carbohydrates are one of the main types of nutrients, and the main energy source of the human diet. It can be found in a wide range of both healthy and unhealthy foods such as bread, bean, cake, popcorn, cookies, and soft drink (Harvard.edu). The consumption of bad carbohydrate that increases your blood sugar should be limit. If the blood glucose stays high for too long, it can develop type two diabetes (womenheath.gov). In addition, carbohydrates are the most…

Weight loss was calculated by the following formula as described by Akhtar et al (2010) Weight loss % = (a - b/a) * 100 Where a and b represent initial and final weight respectively. 2.2 Overall Acceptability (OAA) - Overall Acceptability of the fruit was judged by panel of 5 judges. The fruits were judged on the basis of color, texture and taste. For this, 4 point scale was used. 4= excellent, 3= good, 2=fair, 1=poor. The samples were rated according to deep red colour, crisp texture and…

In this lab we compared fermentation rates under various conditions also known as anaerobic and cellular respiration with an aerobic process. Cellular respiration, is the method when food molecules are broken down from glucose to energy molecules known as ATP. As stated in lab manual BSC 2010L the equation formula is C_6 H_12 O_6+ 6O_2→6CO_2+6H_2 O+energy (including~ 36 ATP) (Upadhyaya, 2018). Fermentation, similar to cell respiration begins with glycolysis; it is the breakdown of glucose with…

Legumes have been an important source of protein, carbohydrate, fat, minerals, vitamins and health- promoting compounds. Legumes play an important role in the traditional diets of the world population and are a valuable material for the food and animal feed industries (Schuszter-Gajzago, 2004). Pigeon pea is a perennial plant widely grown in the semi-arid tropics of Asia, Africa, and the Caribbean. Pigeon pea, besides its main use as dhal, fresh green seeds is used as a vegetable (Nene and…

something gives us energy it means that whatever we drink or eat will fuel us to work. We get our energy from sugars in our food. The biological definition of energy is the strength and vitality required for sustained physical or mental activity. Sucrose and glucose are sugars that provide energy for your body. Glucuronolactone is vital for growth, cell reproduction, blood formation, and protein/tissue synthesis. Inositol helps control the body’s cholesterol level and it can have vitamin C or E.…

Introduction: The purpose of the tests (culture media, motility, enzymes, etc.) we preform on the numerous bacteria in lab is to show any biological or chemical characteristics of the bacteria that may help it survive or adapt in the wild, how it may be useful or hazardous to humans, and use as general knowledge to differentiate bacteria from each other. In the Culture Media test we can use solid and liquid media to grow multiple bacteria in lab. It can help us determine what processes the…

Homogenates of liver were provided. The homogenates were made by homogenizing liver in a 1:20 w/v (1g: 20 ml) ratio in a sucrose-phosphate buffer, in which 250mM of sucrose and 50mM NaPO, with a pH of 7.4 were added. This information was used to conduct an experiment to determine the concentration of DNA, protein, and carbohydrates in different homogenate samples, including heart, liver, and kidney of Bos taurus, while also looking for the diverse protein sizes found in each homogenate sample.…

Designing different experiments regarding the same concept to investigate this topic further would be interesting. One experiment that could be done in the future could be using cold water instead of warm water. In this experiment the students studied how warm water affects the yeast, and learned that warm water activates the yeast enzymes. Where cold water may denature the enzyme, as the students previously reviewed that three factors that affect enzyme activity are temperature, concentration…
