Are the rates of absorption and diffusion constant for all molecules?
no, the rates are different depending on the size of the molecule, the permeability of the membrane, the concentration gradient etc etc.
What is a substance on which an enzyme acts?
Enzymes are biological molecules that catalyze (i.e., increase the rates of) chemical reactions.In enzymatic reactions, the molecules at the beginning of the process, called substrates, are converted into different molecules, called products.Almost all chemical reactions in a biological cell need enzymes in order to occur at rates sufficient for life. Since enzymes are selective for their substrates and speed up only a few reactions from among many possibilities, the set of enzymes made in a cell determines which metabolic pathways occur in that cell.
What is paper chromatography?
Paper chromatography is a technique used to separate a mixture into its component molecules. The molecules migrate, or move up the paper, at different rates because of differences in solubility, molecular mass, and hydrogen bonding with the paper.
Why reactions rates are much slower in organic compounds?
the organic paricles are molecules. Because of strong covalent bonding within the molecule, organic compounds do not readily react. Reactions involving organic compounds are generally slower than inorganic reactions.
How do enzymes affect reactions in living cells?
Enzymes are biological molecules that catalyze (i.e., increase the rates of) chemical reactions. In enzymatic reactions, the molecules at the beginning of the process, called substrates, are converted into different molecules, called products. Almost all chemical reactions in a biological cell need enzymes in order to occur at rates sufficient for life. Since enzymes are selective for their substrates and speed up only a few reactions from among many possibilities, the set of enzymes made in a cell determines which metabolic pathways occur in that cell. Enzymes are known to catalyze about 4,000 biochemical reactions.
How do you speed-up dissolving rates?
Heat and stirring
Identify and define mixtures and solutions and factors that affect dissolving rates?
a mixture is when the solid and the liqid mix together. a solution is when the solid dessolves into the liqiud. the less of the solid you put in the liqiud the more will dessolve. the more that you put in the less dessolves.
What are the rates that effect the rate of dissolving?
The polarity of solute and solvent, the concentration, the temperature.
What is the state in which the rate of dissolving is equal to the rate of precipitation?
It is called equilibrium, which is where forward and reverse rates of reaction are equal.
It is true that cold usually speeds up reaction rates?
No, low temperatures usually slow down reaction rates.
Are the rates of absorption and diffusion constant for all molecules?
no, the rates are different depending on the size of the molecule, the permeability of the membrane, the concentration gradient etc etc.
What are two methods for increasing the dissolving rates of gases in liquids?
increasing the area of contact between the gas and liquid (without shaking it) decreasing the temperature of the system
What happens to the rates of dissolution as the temperature is increased in a gas solution?
The rate decreases.
