What type of reaction occur when atoms combine to form molecules or when molecules break down into atom?
Chemical reactions.
What are molecules that are able to increase and control the rate at which life's chemical reactions occur?
Enzymes.
Are molecules that are able to increase and control the rate at which life's chemical reactions occur'?
Enzymes.
What proteins are vital living things because of they speed up chemical reactions by up to a trillion times?
You are thinking of enzymes a protein molecule that helps other organic molecules enter into chemical reactions with one another but is itself unaffected by these reactions. In other words, enzymes act as catalysts (speed up 1000x) organic biochemical reactions.
What helps chemical reactions occur?
A catalyst helps chemical reactions occur.
Why do chemical reactions in your metabolism happen in water?
l
What are the large complex protein molecules that modify chemical reactions?
The large complex protein molecules that modify chemical reactions are called enzymes. Enzymes act as catalysts, speeding up chemical reactions by lowering the activation energy required for the reaction to occur. They bind to specific molecules called substrates and facilitate the conversion of substrates into products.
Metabolism refers to all of what reactions that occur in cells?
All of chemical reactions in cells breakdown molecules and make molecules.
How else are nuclear reactions unlike chemical reactions?
In nuclear reactions the atom itself changes while molecules and/or structural organisation of atoms do in chemical and physical changes.
Describe the role of energy in chemical reactions?
Chemical reactions that release energy often occur spontaneously. Chemical reactions that absorb energy will not occur without energy.
Where do chemical reactions occur in electrochemical cells?
Chemical reactions occur between the electrolyte and the electrodes in an electrochemical cell.
What chemical reaction produces the sun and energy?
These are not chemical reactions but thermonuclear reactions.
