D_____ J_____ CARBOHYDRATES LAB May 22‚ 2013 Pre-lab Questions 1. The water in test tube No. 1 is a negative control. No reaction is expected to occur because water is not a carbohydrate. Reaction by a negative control is evidence of contamination. 2. The color changes expected for positive test results are Benedict’s test: orange to brick red Tollen’s test: metallic silver Starch iodine test: blue-black 3. Identify each of the samples in Part 1 as monosaccharide

Mashrek International School Investigate the Factors that Affect the Rate of Respiration in Yeast. (Temperature) Fawzi El Ansari Biology HL Title: Investigate the Factors that Affect the Rate of Respiration in Yeast. (Temperature) Aim: The aim of this experiment is to investigate the effect of changing the temperature on the rate of respiration in yeast. This will be done by placing equal amounts of yeast in each beaker that contains the same pH solution. Each beaker will be mixed with glucose

Karmini Mondal Chemistry 245- 061 Biosynthesis of Ethanol from Sucrose Introduction: Ethanol can be created using two methods: acid catalysed hydration of ethylene and through fermentation of sucrose. The purpose of this experiment was to use fermentation to produce ethanol from commercial sucrose (store-bought sugar)‚ using fractional distillation of the fermented solution. The percent ethanol in the fermented solution was then calculated. Mechanism: Results: Mass of conical vial 10.36 g

The aim of this experiment was to investigate the effect that a glucose concentration has on the rate of fermentation. This was done by adding a variety of different glucose concentration into a test tube‚ siting in a water bath. The carbon dioxide would be collected in the test tube and therefore would measure the rate of fermentation. The results parsley supported the hypothesis that‚ “If the glucose concentration increases‚ the rate of fermentation increases‚ therefore the more carbon dioxide released”

Carbohydrate Powders: During an intense weight training workout‚ the glycogen stored in the muscles and liver is the main energy source. Optimal strength and endurance during your workouts it is very important that these glycogen supplies are completely restored before starting a new workout. The best moment to replenish exhausted glycogen supplies is during the first 2 hours after the workout. Easily digestible food products containing lots of fast absorbing carbohydrates high glycemic index are

prevent spread of mosquitoes in our house without buying with high-priced electric mosquito killer lamps‚ insect killer racket or any other device that is too pricy for killing insects and mosquitoes? II. Title Mosquito Trapper Using Sugar And Yeast III. Introduction Our group observed that many people especially children are prone in getting sickness from mosquitoes and may suffer sickness like Dengue and Malaria that may lead to death. Our group also observed that we can create a mosquito

Introduction A melon is any of various plants of the family Cucurbitaceae with edible‚ fleshy fruit. The word "melon" can refer to either the plant or specifically to the fruit. Many different cultivars have been produced‚ particularly of muskmelons. Although the melon is a botanical fruit (specifically‚ a berry)‚ some varieties may be considered vegetables rather than fruits. The word melon derives from Latin melopepo‚ which is the latinization of the Greek μηλοπέπων (mēlopepon)‚ meaning "melon"

Carbohydrates - the Good‚ the Bad‚ the Iffy In the video “Are All Carbohydrates Equally Bad?” Dr. Jason Fung gives us a very good description of how different carbohydrates impact our body. Dr. Fung concluded that fructose‚ a sugar that found in fruits and honey‚ is much worse for us than glucose that found in bread‚ rice‚ and potatoes (Brefere & Drummond‚ 2017‚ p. 68). Even though they are both single sugars‚ they have different effects on our body. The same as people questioned for many years
