What else can I help you with?
What is a substance that lowers the activation energy for a chemical reaction but is not changed or used up in the reaction?
This is called a catalyst. In biology, it is referred to as an enzyme (biological catalyst). Catalysts can also be used to speed up or slow down chemical reactions.
A chemical reaction has inputs called what?
They are called reactants. The outputs are called products.
the reactant that is completely used up in a reaction is called a?
Limiting reactant
What is the thing called that is completely used up in a reaction?
The limiting reagent (aka limiting reactant) is the substance which is completely used in a chemical reaction.
What is the chemical reaction's through which an organism builds up or breaks down materials as it carries out its life process?
The process is called metabolism.
All the chemical processes used to built up or break down materials are called an organisms?
The chemical processes used to build up materials are called anabolism, while the processes used to break down materials are called catabolism. Together, these processes are part of an organism's metabolism, which is essential for maintaining life.
What is a substance that speeds up a chemical reaction with out changing permanently or being used up?
This is called a catalyst.
Is an enzyme used up by the reaction it catalyze?
Enzymes are highly efficient catalysts, and only small quantities are needed to catalyze the reaction of relatively large amounts of materials.
Which term is used to defined substance that participate in chemical reactions?
Substances that participate in the complete, finished reaction are called reactants. Substances that participate for only part of the reaction (in other words, it is used up [or canceled out in the equation]) are called intermediates. Substances that do not participate in the reaction but are still added (and speed up the reaction [their identity is not changed]) are called catalysts.
The amount of a reagent present in a reaction that gets used up is called?
limiting reagent
What decreases activation energy needed for a chemical reaction?
The presence of a catalyst in a reaction will lower the activation energy required to complete the reaction. The catalyst is not used up in the reaction, it is just there to speed it up.
What is a chemical used to speed up a reaction called?
In chemistry it's called a catalyst. In biology it's usually a protein and is called an enzyme.
