It will cause more oxygen to be produced thus result in the increase of the final volume of foam in each measuring cylinder than actual value. The rate of reaction of enzyme will then higher than expected. One possible solution for this error is changing the ruler into another measurement instrument such
Kinetic theory states that molecules are always in constant motion. Kinetic energy and molecule velocity increases as temperature increases. Reactions require collisions between reactant molecules or atoms. In chemical reactions, the reactants change into products when molecule collide with enough energy to break old bonds to make new ones. Collisions increase or become more violent between molecules at higher temperatures or decrease as the temperature is lowered.
Any Increase in substrate concentration after this point cause further increase in the rate of reaction because at Vmax enzyme moleclues are completed saturated with substrate molecules. 3.Effect of temperature At very low temperature enzymes are inactive.Enzymes activity increase gradually with the rse in temperature until a temperature at which the enzyme attains its maximal activity this temperature is called optimum temperature which lies between 37-40 c in humans. 4.Effect of pH Each enzyme has an optimum pH which it attains its maximal activity
Presumably, this shift was to the right due to the fact that when hydrogen ions were added to the reactant side of the reaction, the concentration of H+ ions in the reaction had increased, resulting in a shift to the right; hence, a larger production of dichromate ion found as a product (due to the visible color change found in table 1). Ultimately, in this case the equilibrium system was subjected to a change in concentration of a reacting species and therefore the system responded by attaining a new equilibrium shift to
The researchers were able to produce different explanations to assess the results from each of the experiments. With regard to experiment 1, the researchers correlated the outcome to the influence of temperature on the movement of atoms and molecules. Reanalyzing the definition set for this concept, temperature is analogous to the average molecular kinetic energy of a substance. Thus, it can be said that at higher temperatures, the particles that compose matter move at higher velocities and consequently have higher kinetic energies. Applying this statement to the experimental setup, the average kinetic energy of the molecules of warm water is therefore much higher than that of the cold water.
The hypothesis was proven to be true, because there are more enzymes to react with substrates. For the enzyme—factors affecting, the hypothesis concluded was if the temperature increases, than the enzyme activity will increase. This however was proven wrong, because enzymes become unstable at higher temperatures. They enzyme peroxidase can become denatured in
This would have a positive effect in delivering more oxygen to the tissues and would be especially important if exercise was to be carried out as more oxygen is being use by the tissues. Although the left ward shift would increase the oxygen carrying capacity it could be argued that if there was a rightward shift in the oxygen dissociation curve it could be more beneficial. This shift would cause an increase in the unloading of oxygen into the tissues making more oxygen readily available to the mitochondria of those tissues. In order to determine if a left or right shift does occur the concentration of 2,3 DPG could be measured at altitude and at sea level in a native sea dweller. If in fact there is a left shift as expected there would be an increase in the carrying capacity of the
Bottom Chamber gas: When you apply heat to the bottom chamber, the gas increases in pressure because of the evaporated molecules. More molecules in a space means higher pressure. This higher pressure pushes the liquid up the tube to a lower pressure zone. The molecules hit the liquid with so much force and hit it so frequently that the liquid is forced into another area that has molecules that do not hit it so hard or so frequently. Top Chamber
The melting point for lauric acid in this experiment was 50℃. Explain what is happening during each section of the graph for both cooling and heating in terms of particle motion and energy. When heat is added to a substance the particles in the substance vibrate faster and when vibrate faster the space between the particles increases. The hotter it gets the more the object expands and takes up more space. When a substance is cooled the particles vibrate less causing them to constrict and take up less space.
In general, the greater the temperature difference, the better the driving force of the steam. Additionally, having a high temperature difference will increases the flow rate of the liquid and vapour within the tube. This increase in flow rate causes higher turbulence which results in an increase of the heat transfer coefficient. However, the overall temperature difference has to be within the range of boiling points of the two components as it could affect the quality and the purity of the
