Allosteric enzymes are most effective when the substrate concentration is?
d
TO INCrease the rate of a reaction why would you increase the concentration of the reactants?
For most reactions which involve liquids or gases, increasing the concentration of the reactants also increases the rate of reaction. This is because the number of effective collisions are also increased which speeds up the reaction.
Why absolute alcohol cannot be prepared by fermentation process?
Because alcohol kills things. Most varieties of yeast are killed at 10%, but some can stand up to 14%. So you have to distill it to get above that figure. You can't get pure alcohol by distilling because the alcohol and water blend to make a hazeotrope that evaporates at a lower temperature than either one by itself.
In human the organ the most directly regulates the concentration of the water in the blood?
the kidney's most directly regulate the concentration of water in blood.
What concentration are most intravenous solutions- are they hypertonic isotonic or hypotonic?
Isotonic, because that is close to the concentration in the blood.
Why 70 percent percent ethanol used in labs?
70% is the most effective concentration to denature poteins so killing bacteria. At 95% the ethanol just evaporates and leaves the protein untouched. Below 70% does not denature proteins. It also makes the ethanol less flammable.

Why 70 ethanol is used as disinfectant?
a) 70% ethanol has been found to b most effective in killing microbes.Higher or lower concentrations may not b as effective. b) if u use 90% or absolute ethanol, it will evaporate fast and may not be much effective. c) using higher concentrations will leave its traces on the applied surfaces d) higher concentrations of ethanol are harmful to skin and makes it dry pretty a) 70% ethanol is most effective.higher or lower ones r not as effective b) it evaporates at a slow rate than 90% or absolute ethanol. therefore it is more effective and saves ur ethanol too.. c) higher concentrations alwez leave traces applied surfaces thus addind an unwanted reagent d) 70% ethanol is comparatively less harmful to ur hands.. higher concentrations makes ur skin dry..
What is the most popular legal drug?
I'm assuming you're talking about recreationalbiochemistry here, and that apap (Tylenol) is out of the running.It would be either ethanol or nicotine, depending on exactly how you measure "popularity". (The amount of ethanol sold is far greater by mass, but it takes more ethanol to make an effective dose.)
Who were the first groups to be effected by the concentration camps?
Well technically the first groups affected by the Concentration Camps were Criminals and Political Opponents of the Nazi Party. However, the earliest and most effective group to be effected by the Concentration Camps were the Jews.
Is corn used for gasoline?
Yes, it is the source of corn whiskey. Ethanol can be made from any sugar or starch.Corn doesn't make ethanol. The yeast that consumes the corn produces ethanol as a waste product.
Does Mobile put ethanol in its gas?
In most areas. yes. There should be a sticker on the pump saying if it has ethanol in the gas.In most areas. yes. There should be a sticker on the pump saying if it has ethanol in the gas.
Which country produces ethanol?
US, and then Brazil produces the most ethanol fuel...nd I'm sure every countries that has ethanol industry would produce ethanol fuel!
Is potassium soluble in ethanol?
Yes. Potassium iodide is readily soluble in ethanol and in methanol, the two most common alcohols. The saturation concentration is higher in methanol than in ethanol, i.e., you can dissolve more potassium iodide in the former than in the latter. Potassium iodide-alcohol solutions are widely used in the construction of electrolytic tilt sensors, which require a stable ionic solution for proper operation.
Why is ethanol commonly used in perfumes and aftershaves?
Ethanol, like other alcohols, is a colourless liquid with a sweet distinctive smell. As a good solvent, it is effective for use in perfumes, etcetera, as it effectively dissolves the ingredients and blends them well. Moreover, it is volatile -- due to its tendency to evaporate quickly, it adds an effect on the perfume which helps spread its smell (or diffuse) at a faster rate. Like most alcohols, ethanol also has a cooling effect on the skin, which is evidently soothing, hence an effective solvent for aftershaves.
Solubility of silics gel in ethanol?
Silica gel is insoluble in ethanol and most (if not all) laboratory solvents.
Does Shell gas contain ethanol?
MOST pump gas has at least 10% ethanol. Check the sticker on the pump.
