Extract of sample

Download file to see previous pages For the extracts that included glucose, the process of fermentation continues up to when ADP and P1 inside the extracts were exhausted.
Phosphate was needed in the dehydrogenase of the glyceraldehydes 3-phosphate reaction and glucose stopped in this step after the exhaustion of P1. Since glucose remained, it went through phosphorylation by ATP, but P1 was not released.
The yeast fermentation gave out CO2 and ethanol instead of lactate. In the absence these reactions and in the absence of oxygen, NADH will be accumulated. There would be no new for continued glycolysis. The bisphosphate hexose which accumulated fructose (1,6-bisphosphate) in the form of energetic. The intermediate was at a valley or low point along the pathway between the input reaction energy that was ahead of it and the following energy reactions payoff.
P1 would be replaced by arsenate in a dehydrogenase reaction of glyceraldehydes 3-phosphate to provide acyl arsenate that is hydrolyzed spontaneously. This would inhibit the formation of fructose (1,6-bisphosphate together with ATP thus allowing the formation of 3-phosphoglycerate, that continues in the pathway.
Reaction a, b and c will proceed in the direction shown. This is because the phase of payoff of glycolysis will give out ATP which is exergonic. This phase is typified by five reactions which are similar to those of reaction a, b and c. These include:
From the table, Ethylene glycol enters through the mediated route. This is so because the facilitated or passive diffusion occurs when the specific molecules are transported down the gradient of concentration high to low. In active transport the energy is used in transporting the molecules against the gradient concentration that is low to high as in the case of Ethylene ...Download file to see next pagesRead More

Clinical Chemistry Assignment: Case study and data interpretation
...?Case Study and Data Interpretation Question Plasma Osmolality is the amount of electrolyte water balance in the body. Sodium salts, glucose, and urea are the major causes of osmolality (Moritz ML, 2010). Most of the people confuse plasma osmolarity with plasma osmolality. The difference is the amount of measure used to quantify the amount of solutes in plasma. One litre of plasma osmolality is equivalent to 1 kilogram of plasma osmolarity. Osmolality in blood tend to increase with the body loss of water. For a normal person the antidiuretic hormone will be under stimulation if there is increased rate of osmolality. The presence of antidiuretic hormone leads to reabsorption of water. The urine excreted also becomes more... Study and Data...

...Week1 DQ A fire is started in a fireplace by striking a match and lighting crumpled paper under some logs. Describe all the energy transfers in the scenario. Answer: Match stick is made up of (wood+sulphur) that contain chemical energy Striking the match involves scratching the sulphur end on the rough surface thus producing friction hence kinetic, sound and heat energy are produced at this instance. The match stick lights hence produces light and heat energy that burns the crumpled papers and logs consecutively. Crumpled papers and logs contain chemical energy and while burning produces light and heat energy. Thus: Chemical energy kinetic energy heat energy sound energy light energy heat energy chemical energy... DQ A fire...

...Chemistry Practical Assignment Introduction: Copper carbonate if heated will produce gas and by measuring the volume of gas, we can experimentally establish the correctness of both the equations provided to us. The important thing for finding the correct equation is that the volume of one mole of gas at NTP is 22.4 liter and using this equation we can back calculate the mole or mass of carbon dioxide formed from the copper carbonate used for the experiment (Determining the Correct Equation for the Decomposition of Copper Carbonate, 2003) and hence find out the correctness of the eauation provided. Equipment and Apparatus required for conducting the experiment: The following apparatuses are required to conduct the experiment... to get...
