How are channels regulated biology
WebSubstrate channeling is the passing of the intermediary metabolic product of one enzyme directly to another enzyme or active site without its release into solution. When several … WebCells typically communicate using chemical signals. These chemical signals, which are proteins or other molecules produced by a sending cell, are often secreted from the cell and released into the extracellular space. …
