Because solid food takes more time to digest and to break down the protein and send it to the muscles, it can be best to take a protein shake immediately following a workout, since protein shakes only take about 30 minutes to reach the muscle after ingestion.
selectivity. (analytical chemistry). The ability of a type of method or instrumentation to respond to a specified substance or constituent and not to others. (electronics). The ability of a radio receiver to separate a desired signal frequency from other signal frequencies, some of which may differ only slightly from the desired value.
Each element is unique in terms of reactivity. Most elements react readily in high temperatures, but some react quicker in the cold. The same tendency is observed in respect to pressure, with most elements reacting as pressure increases. However, some others react as pressure decreases. In terms of internal factors, a higher surface area correlates with greater reactivity because reagents have a greater chance of making contact with the substance.
