At 0°C enzyme action is low because the movement of molecules is low. This causes the collision frequency between enzyme and substrate to be low. Increasing the temperature speed up the movement of molecules and thus the collision frequency increases therefore enzyme action increases. Human bio enzymes work best at 37 degrees Celsius. As the temperature raises the shape of the enzyme changes and the enzyme becomes denatured. Temperature above 50 degrees Celsius will denature most human enzymes.

What happens when you heat milk at about 66 degrees to kill most of the bacteria?
When milk is heated to 66 degrees to kill most of the bacteria, the primary thing which happens is its chemical composition is slightly altered. This also kills natural enzymes within the milk.
Why enzymes activity slows down and eventually stops above 35 degree C and below 0 degree C explain why?
the normal working speed of human enzymes is 37 degrees c.If enzymatic activity below the 37 degrees c it works slow and if enzymatic activity is above the 37 degrees c its works very high.
What happens when the pH of the extracellular fluid declines?
the enzymes change
At what temperature do human enzymes work best at?
Enzymes in the human body work best at human body temperature, so about 35-40 degrees (Celsius). A lower temperature would have too low of an effect to be able to sustain life, and a higher temperature causes the enzyme to denature (unravel) and be rendered ineffective.
What happens first at each origin replication?
Enzymes unwind DNA!
What happens to enzymes at 80 degrees?
Degraded
What causes intestinal lactase enzymes to decrease?
Intestinal lactase enzymes usually decrease naturally with age, but this happens to varying degrees.
What process happens at 0 degrees Celsius?
Water freezes at 0 degrees Celsius
What happens to temperature above 0 degrees?
Nothing particular happens.
What happens at 0 degrees Celsius?
Water freezes.
What happens to water at 0 degrees centigrade?
it freezes
What happens 0 C on the celsius temperature scale?
Water freezes at 0 degrees Celsius and at 32 degrees Fahrenheit.
What happens at 0 degrees Celsius to 3 degrees Celsius?
the temperature is getting warmer.
What happens when water reaches 0 celsius?
Water freezesat 0 degrees C
What happens to water below 0 degrees celsius?
it freezes
What happens to liquid water 0 degrees celsius?
It freezes
What happens when the temperature reaches 0 degrees Kalvin?
everything is stopped
