pathway for glucose oxidation. Similar to glycolysis‚ but instead of having pyruvate as the end product it is diverted to other pathways. Supplier of energy to the cell in the form of NADPH (a reducing power for biosynthesis). It is also referred to as hexose monophosphate shunt. *Fate of glucose 6-phosphate (G 6-P) IN THE PPP (S. 71) Taken out from glycolysis and converted into Ribulose 5-phosphate. With the conversion of ribulose 5-phosphate 2 moles of NADPH acquired protons from glucose 6-phosphate

Transport of Solute in Solvent through Osmosis or Diffusion Due to Different Concentration Gradients Passing Through a Semi-permeable Membrane between Cell and Cells Environment Bio 101 Objective: The objective is to simulate passive transport: diffusion of solutes and osmosis of water through a semipermeable membrane (dialysis tubing). The experiment will show how molecules in solution move from areas of higher concentration to areas of lower concentration in the attempt to reach homeostasis
Premium Osmosis Chemistry Diffusion
Osmosis is the spontaneous net movement of solvent molecules through a partially permeable membrane into a region of higher solute concentration‚ in the direction that tends to equalize the solute concentrations on the two sides.[1][2][3] It may also be used to describe a physical process in which any solvent moves‚ without input of energy‚[4] across a semipermeable membrane (permeable to the solvent‚ but not the solute) separating two solutions of different concentrations.[5] Although osmosis does

DIFFUSION AND OSMOSIS: WHAT’S TO EXPECT? Diffusion and osmosis are very important in biological process. Diffusion is the movement of molecules or ions from a region of their high concentration to a region of their low concentration. Osmosis is the diffusion of water molecules across a semipermeable membrane. To gain a better understanding of diffusion and osmosis‚ we examine multiple experiments to show diffusion and osmosis in animal cell‚ plant cell and synthetic cell. In our first experiment

Glucose homeostasis The fed state Presentation copyright © 2007 David A Bender The central nervous system is very largely reliant on glucose as its metabolic fuel; it cannot oxidise fatty acids (but can metabolise ketone bodies in prolonged starvation) glycogen Red blood cells are absolutely reliant on glucose; they have no mitochondria and form ATP only by anaerobic glycolysis triacyglycerol protein glucose triacylglycerol in VLDL triacylglycerol in chylomicrons amino

Glucose Oxidase and Its Various Uses Aaron Truong Since glucose oxidase has an end product called hydrogen peroxide‚ which is a harmful substance to bacteria‚ it can be used to fight bacteria‚ or sterilize objects (can have various uses such as in hand sanitizers‚ toothpaste‚ soap‚ etc)‚ not just biosensors. Another key part in the reaction would be C6H12O6‚ or glucose. Glucose oxidase can be applied to diabetics as mentioned earlier‚ as biosensors work by "keeping track of the

beans. Carbohydrates are the main source of glucose‚ which is a major fuel for all of the body’s cells and the only source of energy for the brain and red cells. Except for fiber‚ which cannot be digested‚ both simple and complex carbohydrates are converted into glucose. The glucose is then either used directly to provide energy for the body‚ or stored in the liver for future use. When a person consumes more calories than the body is using‚ a portion of the carbohydrates consumed may also

Osmosis in Plants Outline: To investigate the effect of varying concentration of a certain sugar solution on the amount of osmotic activity between the solution and a potato chip of a given size. Definition - Osmosis: Movement of a solvent (liquid) through a semi-permeable membrane separating solutions of different concentrations. The solvent passes from a less concentrated solution to a more concentrated solution until the two concentrations are equal. All
