Rennin is an enzyme that converts the soluble milk protein caseinogen into the insoluble protein paracasein, producing the curd that can be processed into cheese or other milk products. Inorganic ions such as metal ions can act as cofactors. The ion may combine with either the enzyme or the substrate to reduce the activation energy. These ions are called activators. Activators are thought to make the enzyme substrate complex form more easily. For example, the action of amylase on starch is quicker in the presence of chloride ions. Calcium ions are required to activate the enzyme rennin. In this demonstration, calcium ion is removed by precipitating it as calcium citrate. In the tube containing the sodium citrate, calcium citrate forms as a precipitate. what effect changing the concentration of calcium ions has on the rate of coagulation of milk how calcium ions influece the activity of rennin in bringing about the coagulation of milk because it does
No, not really. Diffusion works when molecules move from an area of higher concentration to an area of lower concentration. They move independently of one another. So even if you have a high level of NaCl, the glucose concentration will diffuse in the same manner.
calcium hydroxide turn red litmus paper into blue because it is a base. it does not have any effect on blue litmus paper.
Hydrogen gas does not directly react with limewater (calcium hydroxide solution) to produce a visible change. Limewater is typically used to test for the presence of carbon dioxide, which would cause the solution to turn milky due to the formation of insoluble calcium carbonate.
The mass of calcium oxide does not directly affect the temperature when it reacts with water. The temperature change is primarily dependent on the amount of heat released during the exothermic reaction between calcium oxide and water. This heat release is determined by the stoichiometry of the reaction, not the mass of the reactants.
Increasing the CO2 concentration in the atmosphere
the rate of coagulation increases as the concentration of calcium ions increase.
It hinders it. EDTA, a commonly used anticoagulant, works by chelating calcium. This also has the consequence that large volumes of blood transfusions causes calcium deficiency.
so far ive got thermostatcally controlled water bath test tubes microscope but cant think of anythig else!!there must be more
EDTA binds to calcium ions, which are essential for the coagulation cascade. By chelating calcium, EDTA can inhibit the activity of clotting factors that require calcium for their functions, ultimately affecting the clotting process.
For the enzyme to work, its particles must collide with the particles of the substrate. The more particles there are per unit volume, the more frequent the collisions will be. Thus changing the concentration of either chemical will have the same effect.
Increasing the concentration of an acid would increase the rate and vigor of the reaction involving a metal such as magnesium.
Having the effect of retarding or inhibiting the coagulation of the blood.
The PTT test can be used to monitor the effect of heparin on a patient's coagulation system.
Changing the concentration of S2O8^2- ion in a reaction can affect the reaction rate. Increasing the concentration of S2O8^2- typically results in a faster reaction rate because there are more reactant particles available to collide and react. Conversely, decreasing the S2O8^2- concentration can slow down the reaction as there are fewer reactant particles available to collide.
The resting membrane potential is maintained by the distribution of positive and negative charged ions across both sides of the cell membrane. At rest, calcium concentration in cells of the heart is low as compared to the outside. At action, calcium channels in the membranes open, thereby allowing calcium to rush into the cells. So raising the heart rate.
Caffeine: Caffeine has a small effect on calcium absorption. It can temporarily increase calcium excretion and may modestly decrease calcium absorption, an effect easily offset by increasing calcium consumption in the diet.
the rate is affected by concentrations raised to the power of an exponent
