However, use of the gal is deprecated by ISO 80000-3:2006. The gal is a derived unit, defined in terms of the centimeterâgramâsecond (CGS) base unit of length, the centimeter, and the second, which is the base unit of time in both the CGS and the modern SI system.
It has been shown experimentally that if the amount of the enzyme is kept constant and the substrate concentration is then gradually increased, the reaction velocity will increase until it reaches a maximum. After this point, increases in substrate concentration will not increase the velocity (delta A/delta T). This is represented graphically in Figure 8. It is theorized that when this maximum velocity had been reached, all of the available enzyme has been converted to ES, the enzyme substrate complex.
As the enzyme concentration increases the rate of enzyme activity increases up to a level where it becomes constant. This is because the more the enzymes are available, the m â¦ ore substrates are broken in less time.ncreasing temperature increases the rate because the substrate has more kinetic energy, so is more likely to collide with the enzyme for the reaction to take place. Too much heat causes the bonds which hold the enzyme in its very specific shape to break, meaning it can no longer function (is denatured).
