yes it is required in small amounts. The lesser the catalyst, the better is its efficiency.
Only small amounts of enzymes are required for reactions within cells because enzymes are reused.
The catalyst decrease the needed activation energy.
yes
No, a catalyst is used only to speed up a reaction. An example of a catalyst is Manganese.
small amounts of gravity
vitamins are required in small amounts by the body.
Only small amounts of enzymes are required for reactions within cells because enzymes are reused.
A trace element.
A catalyst is a substance, usually used in small amounts relative to the reactants, that modifies and increases the rate of a reaction without being consumed in the process.
You may be thinking of the various vitamins.
Poison - the opposite to catalyst
The catalyst decrease the needed activation energy.
produce in small amounts the hydrochloric acid required for the digestion of food ,,
A catalyst must change the rate of a chemical reaction. It must be unchanged at the end of the reaction.
A catalyst lowers the activation energy of a reaction.
There are a number of metals which are called trace elements, that the body needs in very small amounts; these include copper and zinc.
