Protein catalysts which cause reactions to occur at temperatures and ph values which are common to living cells are called

The proteins that helps in decreasing the activation energy of a reaction to occur at a definite temperature range and pH value in a living cell are called as the enzymes. These proteins are considered as the biocatalysts. All these biocatalysts are made up of proteins. All the enzymes are proteins but all proteins are not enzymes. Hence the answer is enzymes.
