Alternatively, the response might be turned on or off by the product of an enzyme reaction.
Galactose is converted to glucose by a series of three enzyme reactions.
This means that the rate of the enzyme catalysed reaction is actually limited by diffusion.
He also studied the biochemistry of material processing by plants, and enzyme reactions in plant cells.
He had invented the now standard stopped flow device to measure the existence of the enzyme-substrate complex in enzyme reaction.
This way of measuring enzyme reactions is called progress-curve analysis.
However, the initial products of the enzyme reactions are sometimes more toxic than the original chemical.
Some enzyme reactions produce light and this can be measured to detect product formation.
It often refers to a phase II enzyme reaction.
The major contribution of Henri was to think of enzyme reactions in two stages.
