When a person gets hypothermia the enzymes in their body become less active how does this change affect the body's chemical reaction?
most chemical reactions require a certain input of energy, meaning they need to be at a certain temperature. when the temperature is too low or too high, these chemical reactions cant take place.
Is it true that lowering the temperature slows down most chemical reactions?
most chemical reactions dealing with enzymes preform best in a certain small temperature range, so increased or decreased temperatures could result in the slowing down of reactions
What is a chemical change and a chemical reaction?
There are certain types of chemical reactions describing what happens to certain reactants, such as combustion, single replacement, double replacement, etc. All of these processes change one kind of reactants (original substances) into different products (new substances) with a new combination of atoms arranged in a way to have completely different properties.Chemical reactionsare chemical changes. Reactions are just more specific.
What are non commutative substances in chemistry?
substances made by non-commutative reactions, where the ractants have to be put in a certain order.
Proteins that speed up certain chemical reactions?
an enzyme
Are chemical reactions always spontaneous when H is negative and S is negative?
No, when H and S are both negative, the reaction will only be spontaneous below a certain temperature
How can you be certain that a chemical change has occurred?
Signs of chemical reactions may be: - Gas release - Formation of a precipitate - Change of color - Change of odor - Change of pH - Change of aspect - Change of viscosity - Change of the temperature - Visible formation of new compounds
How a substances gets electric charge?
basically metals get charged by getting extra electrons or by missing them. baut certain substances get there charges by a physical phenomenon ,like friction ,heating,or any chemical reactions , it all results in electron transfers, and the substance get charged.
What is the role of energy in chemical reations?
All chemical reactions need a certain amount of activation energy to get started.
A sign that a chemical reaction is taking place is release of energy in the form of?
Most common chemical reactions are exothermic. This means that when the reaction occurs, they release heat. Some reactions are endothermic, which means they absorb heat.
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 serve as enzymes?
catalysts are especialized proteins that help your bidy carry out certain chemical reactions
