Cell Respiration Lab Research Question What is the optimal temperature for germinating pea-seeds where the rate of respiration is the greatest? Background Information Cell Respiration refers to the biochemical process conducted by the cells of an organism that combines glucose and oxygen to produce energy in the form of ATP, along with two by-products, water and carbon dioxide. The equation representing this chemical reaction is shown below. C6H12O6 + 6 O2 6 CO2 + 6 H2O + ATP Although plants and

exact numerical results being 65+8 and 70 +12 mm of CO2 per hour for Glucose and Fructose compared to only 1+2 mm of CO2 per hour for Galactose. Meanwhile, Disaccharide sugars also showed large differences as Sucrose and Maltose both outproduced Lactose (66+11 and 43+11 mm of CO2 per hour compared to 1+2 mm of CO2 per hour respectively). We observed that Galactose and Lactose sugars produced close to zero carbon dioxide in the fermentation of S.

Galactosemia Introduction: Galactosemia (a high blood level of galactose) is caused by lack of one of the enzymes necessary for metabolizing galactose, a sugar present in lactose (milk sugar). Galactosemia is a clinically heterogeneous autosomal recessive congenital disorder of metabolism. Galactosemia is mostly observed in new born babies. There are two types of galactosemia in found, Classic galactosemia and variant Galactosemia  Classic galactosemia, results in potentially fatal complications

sugar called galactose cannot be digested by the body. When galactose cannot be digested, it builds up in the body and causes damage to the liver, brain, eyes, kidneys, central nervous system, and other body systems. Galactose is mainly found in dairy products but is also in many other foods. The diet for galactosemia involves avoiding foods and drinks that contain galactose. You should follow this diet for your entire life. What are tips for following this plan? Foods that contain galactose are not allowed

Galactosemia is a disorder that adherently affects the way the body processes a simple sugar called galactose, which is a breakdown product of lactose (1). Lactose is found in all dairy products and in multiple baby formulas. Most importantly, the signs and symptoms of Galactosemia result from the inability to use galactose to produce energy (1). Classic Galactosemia occurs in 1 in 30,000 to 60,000 newborns (1). However, Galactosemia type II affects fewer than 1 in 100,000 newborns and type III seems

Lactose is a disaccharide sugar that is found in especially milk. This is the definition of Lactose according to Google: Lactose a sugar present in milk. It is a disaccharide containing glucose and galactose units. Like I said Lactose is mostly found in dairy products like cheese, milk, butter, and ice cream. Too much Lactose is bad for your body because it can cause type II diabetes. Lactose can even cause cancer which can lead to

modifies the process of breaking down galactose, a simple sugar. Galactose is essentially part of a common sugar named lactose. Furthermore, it can also be present in a variety of foods, especially in baby formulas and dairy products. “Galactosemia” is a term that represents that the blood contains too much galactose. There are several types of galactosemia, such as classic and clinical variant galactosemia (type I), galactokinase deficiency (type II), and galactose wpimerase deficiency (type III)

needed to break carbohydrates down into simpler components that can easily be used for energy. However, enzymes are very specific and only react to certain substrates, as shown by part A of this lab, where glucose trinder was exposed to glucose, galactose, mannose, and lactose, but only reacted with glucose. To show how pH can have an effect on enzymatic reactions, lactose was exposed to lactase at different pH 's, the data showed that the reactions occurred more easily at the more neutral pH 's (closer

Slide C: This was mixed with 15 microliters of erythrocyte suspension, 10 microliters of Con A, and 10 microliters of Galactose. Slide D: This was mixed with 15 microliters of erythrocyte suspension, 10 microliters of Con A, and 10 microliters of Mannose. Discussion The results for cell staining on slides 3 and 4 showed a noticeable purple staining for both samples. Slide 3 (Galactose) showed that the cheek cells were tightly bound together with a purple color while slide 4 (Mannose) showed the cheek

diarrhea and prolonged conjugated hyperbilirubinemia are the commonest presenting symptom. Jaundice and hepatomegaly develop early. Cataract also develops with time. Untreated disease may progress to cirrhosis. Ascites may develop with continued galactose ingestion as the disease progresses and is present in most infants who die due to this

task? The product of the natural reaction catalysed by the enzyme is galactose and glucose, from a lactose substrate. The enzymes catalyses the enzymatic hydrolysis of lactose substrate (disaccharide -> monomers: galactose and glucose) by breaking the ‘glycosidic bonds’. The additional molecule required for the completion of hydrolysis is water (H2O).

What is the impact of utilizing immobilized enzymes in the lactose industry? Introduction Enzymes are protein molecules that act as catalysts (they speed up chemical reactions) in living organisms. Enzymes are specified, however, they are not permanently specified- they do not change from reactions, which allows them to be reused. Despite the fact that they can be reused, if enzymes are in a solution with their reactants, it is difficult to separate them. Without enzymes, the chemical reactions

Greek yogurt, although created in the Middle East and Eastern Mediterranean hundreds of years ago, has become a staple in many homes across the United States. With its white, creamy texture and often tangy taste, it is a great snack to pack in protein (“FAGE...” 2013). Greek yogurt is also a wonderful source of calcium, and it is gluten-free and vegetarian-friendly (“FAGE...” 2013). Greek yogurt is not just eaten as a wholesome snack, though. It is often used as a substitute for mayonnaise, and it

alternate induction agents, antibiotic and glucose adding on to inducing of β-galactosidase in E.coli. The β-galactosidase is normally switched off in E.coli except in the presence of lactose; the enzyme β-galactosidase breaks down lactose into galactose and glucose. (Matthews 2005). The lac operon or lactose operon is essential for the transportation of lactose in E.coli. In the lac operon three structural genes, z, y and a genes, are transcribed into an mRNA molecule that synthesizes 3 proteins

Disaccharides There are three dietary monosaccharides called glucose, fructose, and galactose. Monosaccharides are single-ring structures, and they form the basic building blocks for more complex sugars, such as disaccharides. Disaccharides are referred to as double sugars because they are made from a combination of two monosaccharides. In dehydration synthesis, water is removed and two monosaccharides become a disaccharide. Dehydration Synthesis, or condensation reaction, is when we can take these

different forms of carbohydrates are found in many foods. Examples of monosaccharides are glucose, fructose and galactose which can be found in fruits, veggies and some dairy products. Table sugar is a disaccharide formed of glucose and fructose which occurs naturally in fruits and artificially in many processed foods. Lactose is another disaccharide, composed of glucose and galactose which is the main sugar in milk. Starch, glycogen and cellulose are all examples of polysaccharides. The final test

small intestine. The epithelium absorbs these simple saccharides (such as dextrin and maltose). These sugars, in their simplest forms (as glucose, fructose, or galactose), will enter the capillaries where they enter the blood stream via different transporters such as the GLUT transporter (a facilitative sugar transporter)(7). Fructose and galactose will enter the liver via the hepatic portal system where they are broken down to glucose. Glucose is already at an optimal state for use in tissues at the

enzyme, L- fucosyl tranferase that adds L-fucose to the terminal galactose to form the H antigen (Ahmed, 2007). Individuals with with blood grioup A and AB contain the A gene which is found on chromosme 9. This gene encodes N-acetylgalactosaminyl transferase which adds N- acetylgalactosamine to the terminal galactose of the H antigen, to create the A antigen (Ahmed, 2007). The B gene encodes D galactosyl transferase which adds D-galactose to the ternminal glactose of the H antigen to create B antigen

Fructose, glucose and galactose are contained in monosccarides. In this spread, β-D fructose also known as levulose and fruit sugar are presented and fructose is the sweetest of the monosaccharides which help to sweeten the spread. β-D-glucose also has presented in this spread which can be found in honey and fruits. Glucose is good in metabolized in the body for energy. For galactose, it is an isomer of glucose with a hydroxyl group on carbon 4 reversed
