Vedclass · Answer

(C) $1$. Enzymes are biocatalysts that are generally proteinaceous in nature. $2$. Most enzymes are denatured at high temperatures,but enzymes isolated from thermophilic organisms (like thermophilic bacteria) remain stable and active at temperatures as high as $80 \ ^\circ C - 90 \ ^\circ C$. Thus,statement $A$ is correct. $3$. Enzymes are highly specific in their action,meaning a particular enzyme acts on a specific substrate. Thus,statement $B$ is correct. $4$. Almost all enzymes are proteins. While some nucleic acids (ribozymes) can act as enzymes,lipids do not function as enzymes. Thus,statement $C$ is incorrect. $5$. Enzymes exhibit maximum activity at a specific $pH$ known as the optimum $pH$. Thus,statement $D$ is correct.

Three of the following statements are correct and one is incorrect. Identify the incorrect statement.
