When body temperature drops below normal do chemical reactions proceed too rapidly and do body proteins begin to break down?
Pruey
No, when body temperature drops below normal the body will slow down in its functions and go into "preservation mode".

What do enzymes do in the cell?
The enzymes in the cell act as catalysts for chemical reactions. They lower the activation energy of these reactions in order to speed up the reaction rate.
Why is there an incubation step after the addition of the substrate in ELISA reactions?
There needs to be a conversion of the substrate for the chemical reaction to provide an H+ ion for the color change needed for ELISA. The temperature essentially lowers the activation energy to allow for this reaction to proceed.
How do enzymes help accelerate reactions?
Chemical reactions involve collisions between molecules. most collisions don't have either the right orientation or enough energy for the reaction to proceed. the molecules just bounce off each other, unchanged. incidentally that is why reactions proceed faster as the temperature increases - high temperature means molecules are moving faster and are more likely to have the required energy to react.Enzymes are protein catalysts that force reactant molecules into the correct orientation and lower the required energy for a collision to produce a reaction.
How do enzymes make reactions occur faster?
enzymes are biological catalysts. a catalyst is a chemical that increases the rate of a reaction and itself is not changed at the end of the reaction and does not change the nature of the reaction or its final result. catalysts make reactions go faster at lower temperatures by lowering the activation temperature required , thus ensuring that a larger percent of the population of reactant molecules will have sufficient energy to participate in the reaction.
What type of reaction occurs when one compound takes the place of another compound in the reaction?
A single-replacement reaction
What are adaptations of daphnia?
Daphnia are cold-blooded animals, and they do not thermoregulate. This means that their body temperature is the same as the water they are floating in. The chemical reactions that occur in the cells of Daphnia are dependent on certain enzymes, or proteins, to help the reactions proceed. As you increase the temperature of the water, the metabolism of the Daphnia increases as well, because chemical reactions occur faster at higher temperatures. This means that the heart rate will speed up in order to provide oxygen to the cells as the metabolism increases. However at 40 degrees Celsius, the enzymes break down, and the chemical reactions can no longer occur, so metabolism stops and the Daphnia dies
What do enzymes do in the cell?
The enzymes in the cell act as catalysts for chemical reactions. They lower the activation energy of these reactions in order to speed up the reaction rate.
When is a reaction said to be endothermic?
The chemical reactions that must absorb energy in order to proceed. These are endothermic reactions.
How do chemical reactions proceed?
Atomic, and subatomic particles go to different atomic, and subatomic particles.
How do an enzymes speed up chemical reactions in cells?
They lower the activation energy required for the reaction to proceed.
What is the relationship of genes and enzymes?
The link is that a metabolism is made up of different reactions and these reactions have to be catalyzed by enzymes, because without these enzymes most of the reactions in the metabolism wouldn't proceed.
Are nematodes ectothermic or endothermic?
There are other chemical reactions that must absorb energy in order to proceed. These are endothermic reactions. So I think they are Endothermic...
Why is there an incubation step after the addition of the substrate in ELISA reactions?
There needs to be a conversion of the substrate for the chemical reaction to provide an H+ ion for the color change needed for ELISA. The temperature essentially lowers the activation energy to allow for this reaction to proceed.
How do enzyms function?
Enzymes allow reactions to occur at body temperature, that would not normally occur at that temperature. They accomplish this by lowering the amount of activation energy needed to have the reaction proceed.
What are proteins essential for?
Proteins are essential for Biochemistry To Proceed , and Life To Occur.
What does a two direction arrow indicate in a chemical equation?
It indicates that the reaction can proceed in both directions. It could also mean that the reactions are in a dynamic equilibrium.
How could you increase the rate of fission reactions?
Fission does not respond to changes in temperature and pressure like chemical reactions do. In a nuclear reactor, the fission chain reaction can be sped up by removing rods of cadmium, which absorb neutrons. These are in place to prevent the reaction from occurring too quickly. Remove them, and the chain reaction may proceed out of control.
