What happens to enzymes at -0 degrees?
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.
How does temperature change the action of enzymes?
The temperature is one of the key factors that can denature an enzyme. When the temperature is too low or two high, the enzyme will denature and not function.
Dehydration synthesis and hydrolysis are accomplished in cells by?
the action of enzymes
What are the vitamins that assist the chemical action of enzymes?
its a type of cofactor more precisely called a Coenzyme
What conclusion can be drawn about the action of the enzymes as the temperature increase?
enzyme A becomes less effective earlier than enzyme B enzyme b stays effective at higher temperatures than enzyme a
The graph below shows how two different enzymes react with a substrate as the temperature increases. Based on the results what conclusion can be drawn about the action of the enzymes as the temperatur?
enzyme B stays effective at higher temperatures than enzymes A

Why is temperature a factor of cellular respiration?
Temperature can effect enzymatic action of all cellular activities to a great degree. Typically increasing the temperature will stimulate enzymes while decreasing it will hinder their activity. If the temperature is too high the protein enzymes will denture and become useless. If the temperature is too low the activation energy required to initiate enzyme action will not be able to be overcome and the enzymes will be rendered inoperable.
Do Temperature of the cytoplasm influence the action of enzymes?
Yes, enzymes have optimal working temperatures that differ from enzyme to enzyme
What conditions affect the action of an enzyme?
If the enzymes are heated they can become deformed and not work as well.
Does enzymatic action in a chemical reaction result in an increase in temperature?
Yes it can, but more commonly an increase in temperature increases enzymatic action.

Dehydration synthesis and hydrolysis are accomplished in cells by?
the action of enzymes
What makes fat more available to digestive enzymes?
Bile emulsifies the fat, breaking it down into smaller pieces. This increases the surface area of the fat particles and makes it more available for action by digestive enzymes.
How do chemical reactions occur at the relatively low temperature found within Cells?
They occur under the strict and highly specific action of Enzymes.
What causes tomatoes to ripen much more slowly in a refrigerator than they do if left on a table at a room temperature?
Low temperatures reduce the action of ripening enzymes. When tomatoes are stored in a refrigerator the colder temperature causes ripening enzymes to slow down, which slows the ripening process.
