The colour red gives the highest rate of photosynthesis (89 bubbles per minute) with blue giving the second highest rate of photosynthesis (70 bubbles per minute)‚ and yellow giving the third highest rate of photosynthesis (64 bubbles per minute) and green with by far the least (44 bubbles per minute). Although‚ we can see no direct correlation between the rate of photosynthesis and

LAB REPORT Lab #9- Yeast Fermentation Dates of performed work: 3/26/18 Date submitted: 4/23/18 Abstract Yeast are unicellular fungi which act as facultative anaerobes. This means that yeast is able to produce ATP by aerobic respiration while oxygen is present‚ but are also capable of anaerobic respiration if oxygen is not available. This is called fermentation.

Carbohydrate and Diabetes Research NUR 115 AM The articles that I researched for this project were interesting and shed light on the relationship between carbohydrates and diabetes. Some of the information that I learned will be useful in my nursing career. Carbohydrates fill numerous roles in living things‚ such as the storage and transport of energy in the form of starch and glycogen etc. The basic carbohydrate units are called monosaccharides‚ such as glucose‚ galactose‚ and

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

or a dark purplish black‚ then the test for starches is positive. If DI water‚ and sucrose are tested for proteins using biuret reagent‚ then they will show a negative result. To explain‚ both DI water‚ and sucrose alone do not contain a trace of protein. In addition‚ deionized water is commonly used in experiments as a negative control. In both experiments‚ if the DI water is tested for a protein or starch‚ then it will come back as a negative. If milk solution‚ and 50% egg white solution are

T2:BIOCHEMISTRY AND ANALYSIS:DETECTION OF FATS‚PROTEINS AND CARBOHYDRATES OBJECTIVE The main purpose of the experiment is to understand some general tests that detect fats‚proteins and carbohydrates in foods. INTRODUCTION Carbohydrates are also known as sacharides. There are 4 main groups of carbohydrates‚which are monosaccharides‚ disaccharides‚ oligosaccharides and polysaccharides. Carbohydrates play an important role in living organism as it is the energy storage‚ and it also plays

The substrate which I chose to further investigate was fructose. Fructose is a fruit sugar which is one of the three‚ along with glucose and galactose‚ dietary monosaccharides that are directly absorbed into the bloodstream during digestion.

Charlene Villanueva - Biology Charlene Villanueva - Biology Starch‚ Glycogen and Cellulose Independent Research A polysaccharide is a long chain of monosaccharide molecules‚ held by glycosidic bonds. They are usually not sweet in taste‚ insoluble in water and often do not produce crystals when water is taken out. Starch Starch is a complex solid carbohydrate‚ consisting glucose molecules held together by glycosidic bonds. It is a storage polysaccharide. They can be found in fruits‚ seeds‚ roots
