Question

Part A A plot of enzyme velocity against temperature for an enzyme indicates little activity at 0 degrees Celsius and 40 degrees Celsius peak activity at 35 degrees Celsius. The most reasonable explanation for the low velocity at 0 degrees Celsius is that O both the frequency and energy of enzyme-substrate collisions are low 0 the hydrogen bonds that define the enzyme's active site are broken as temperature increases 0 the enzyme was denatured at this temperature O substrate binding at the active site is thermodynamically unfavorable at low temperature Submit Request Answer Next > Provide Feedback

Explanation / Answer

The reasonable answer for the low velocity at 0 degree celcius is that both the frequency and energy of enzyme substrate collision are low. In low temperature. This is due to the decrease in kinetic energy and velocity that follows temperature decreses. As in low temperature the kinetic energy of the molecules is low, the collision between enzyme and substrate is also low. With low velocity there will be more time between collision which causes less molecules to reach activation energy which decreses rate of reaction.
