Living organisms need to make energy from food in order to allow rapid cell reproduction and maintain life. Glucose, amino acids, and fatty acids are utilized to generate adenosine triphosphate (ATP), a coenzyme used for an energy carrier. The primary source of carbon and energy for humans and most eukaryotes is glucose [1]. But, since it is polar in nature, glucose cannot diffuse through the plasma membrane’s lipid bilayer. This causes the need for glucose to be transported by a glucose transporter, on the plasma membrane, into the cell. After the uptake of glucose, glycolysis is used to convert the glucose into pyruvate. Glycolysis is a pathway that includes ten enzyme-catalyzed reactions.
When glucose enters the cell, it is phosphorylated by an enzyme, hexokinase, and uses ATP to keep the glucose concentration low in order to continually transport glucose into the cell by the glucose transporters. This produces glucose 6-phosphate, which has a negative charge, preventing glucose from diffusing out of the cell [2]. Glucose 6-phosphate is then rearranged by phosphoglucose isomerase to form fructose 6-phosphate. Fructose 6-phosphate is catalyzed by phosphofructo-kinase-1 coupled with ATP, forming fructose 1,6-bisphosphate. Since the molecule is now destabilized, the fructose 1,6-bisphosphate is split by aldolase to form glyceraldehyde 3-phosphate and dihydroxyacetone phosphate [2]. Dihydroxyacetone phosphate is then converted into glyceraldehyde 3-phosphate by

Glucose
Introduction: What influence does Glucose have within food and chemistry itself? We all know that Glucose itself is a simple monosaccharide that we normally call Sugar, however what does it all really cover within the basis of food? So let’s get down to the bottom of this and discover what role Glucose plays within the chemistry of food.
Background: Glucose, which is also called D-glucose or Dextrose is a monosaccharide within one of the
properly, it requires energy which mainly comes from carbohydrates and fats we would take in as food. Carbohydrates are broken down into glucose which is soluble in blood. It is transported by the blood cells all around the body where it reacts with oxygen and will produce carbon dioxide (CO2), water (H2O) and energy.
C6H12O6 +6O2 ------------6CO2 +6H2O +Energy
Glucose + Oxygen Carbon Dioxide + Water + Energy
Carbon dioxide and water are formed during respiration(the burning of food in the
Glucose is the primary energy source for the brain and it also serves as a source of energy for cells throughout the body. The energy provided by glucose helps the cells to carry out nerve cell conduction, muscle cell contraction, active transport and the production of chemical and metabolic reactions. These processes are all essential for the bodies survival and all require glucose to carry out their actions. Blood glucose regulation is the process by which the levels of blood glucose, are maintained

Introduction
In the modern society people live in today, people have started to take in good cuisines. It became more than just a necessity. Eating and consuming foods are required for every individual as people need it to survive, but too much can be taken in which then, results in harming the body. Desserts such as cake and ice cream are sweet because they have a high concentration of sugar. Sugar
The Effects of Soy food on Blood Glucose in Type 2 Diabetes Mellitus
INTRODUCTION
In clinical scenarios, nurse practitioners often encounter such questions from diabetic patients as ‘Can I take soy food to reduce my blood sugar level?’ or ‘Can soy food prevent diabetes?’ or ‘Does eating soy food really help on my diabetic condition?’
Type 2 diabetes mellitus (T2DM) is one of the most common chronic diseases with significant morbidity and mortality, which has become a global-wide health challenge
In laboratory studies of healthy young adults submitted to recurrent partial sleep restriction, marked alterations in glucose metabolism including decreased glucose tolerance and insulin sensitivity have been demonstrated (Spiegel et al. 2005). A pooled regression analysis in adults also suggests that a reduction in one hour of sleep per day would be associated with a 0.35 kg/m2 increase in BMI (Cappuccio et al. 2008). In Japan, a study of adolescents observed a dose-response relationship between
Objective: There are some studies about the good effects of herbal drugs on blood glucose . This clinical trial was designed to evaluate the synergism effect of Peganum harmala,Quercus infectoria,Vaccinium myrtillus, Citrullos colocynthis, Securigera securidaca with different nature on blood glucose .
Methods: Twenty qualified type 2 diabetic patients were enrolled in this cross over double- blinded clinical trial for receiving two months drug and also two months placebo. The subjects divided into
many other intracellular metabolic pathways . During, gluconeogenesis there is an important process in which there is a conversion of glucose to pyruvate which is known as glycolysis. This process will require three irreversible steps that have a very high negative free energy that is in the forward reaction. So, in order to have a conversion from pyruvate into glucose, the pathway will require the use of enzymes, which will allow the bypassing of these irreversible steps. One of the enzymes that is
Blood Glucose Regulation
Homeostasis is what physiological systems in our bodies do in order to maintain a stable internal environment. Stability is held together by the coordinated responses of the components involved to any stress or unfamiliar situation that the human body is put under that could disrupt its normal functioning conditions. Homeostasis must be maintained constantly in order for our bodies to be able to function properly and not under stress which could have major effects later on
THE EFFECT OF GLUCOSE CONCENTRATION ON ANAEROBIC RESPIRATION IN YEAST
INTRODUCTION:
Yeast, also known as a saccharomyces cerevisiae, is single celled eukaryotic cells that are in the kingdom fungi and are unicellular organisms which normally reproduce asexually by budding at a very high rate. Scientists quite often decide to work with yeast because of its features fast growing rate and the fact that yeast 's DNA can be easily manipulated. Some types of yeast can be found naturally on plant or in
