Which term describes energy that is required to get chemical reactions started?
Activation energy describes the energy that is required to get chemical reactions started.
Is the activation energy for chemical reactions in living things high or low?
Activation energy of reaction is the same regardless if it is in living organism or in test tube. Yet, the energy of activation can be lowered if catalyst is present. In living things catalyst lower the energy needed for chemical reactions.
Which statement best explains how enzymes speed up chemical reactions?
Enzymes lower the activation energy of a chemical reaction.
Is it true or false that all chemical reactions require an initial input of energy called catalysis?
FalseAll chemical reactions require an initial input of energy called activation energy.
How does enzymes speed up chemical reactions in your body?
Reactions in the body need a certain amount of energy, called activation energy. Most reactions don't take place because this activation energy is too high. The enzyme bonds to the molecule which diminguishes the activation energy, so the reaction can take place. These enzymes de-bond from the new formed molecule afterwards.
What term describes energy that is required to get chemical reactions started?
Activation energy describes the energy that is required to get chemical reactions started.
Which term describes energy that is required to get chemical reactions started?
Activation energy describes the energy that is required to get chemical reactions started.
How do enzymes affect the activation of energy in chemical reactions?
they lower the activation energy.
How is activation energy relates to the start of chemical reactions?
A chemical reaction begin only if the activation energy has a specific value.
WHAT TERM DESCRIBES ENERGY THAT REQUIRES TO GET CHEMICAL REACTIONS STARTED?
Activation energy describes the energy that is required to get chemical reactions started.
What is activation effect?
Activation effect is the effect of spontaneous reactions that release energy. When reactants mix and produce a series of chemical potential energies, the outcome of the reaction results into an activation effect due to the reactions.
Why is chemical energy needed in all chemical reactions?
To initiate a chemical reaction an activation energy is necessary.
Do catalysts lower the activation energy of chemical reactions?
Yes, they do.
Is the activation energy for chemical reactions in living things high or low?
Activation energy of reaction is the same regardless if it is in living organism or in test tube. Yet, the energy of activation can be lowered if catalyst is present. In living things catalyst lower the energy needed for chemical reactions.
What are Biological proteins that lower the activation energy for chemical reactions?
