In a general sense, a catalyst is able to lower the activation energy required for a reaction and lower the time required to reach the transition state of the reactants. The catalyst is also not consumed during the reaction, so it can be used repeatedly.
Only small quantity is need for a reaction They are specific. One catalyst is need for specific reaction only Physical properties may change during a reaction but no it does not take part in the reaction.
Enzymes are specific in actions.
Enzyme activity depends on pH.
Most enzymes are proteins.
but all catalysts aren't enzymes...
No. Generally they are not catalysts
Enzymes are natural catalysts, these natural catalysts speed up reactions.
These elements are not used as catalysts.
Catalysts help chemical reactions: the activation energy is lowered, the reaction rate is accelerated. Catalysts are not exhausted in the reaction and are recyclable.
No
Some, but not all, substances do so. Such substances are known as catalysts.
It depends upon the catalytic properties that make them orders of magnitude more potent than those of the best chemical catalysts. Enzymes as natural catalysts, act by lowering the height of the kinetic barrier; that is, stabilize the transition state with respect to the uncatalyzed reaction. What apparently makes enzymes such powerful catalysts are two related properties: their specificity of substrate binding combined with their optimal arrangement of catalytic groups.

The three properties of color are the spectrum, the chromaticity, and the primary colors
the three basic properties in addition are associative, indentity,and commutative.
No. Generally they are not catalysts
