Are all enzymes proteins

Answer 1

Most, but not allPrior to 1967, the assumption was that all biological catalysts were proteins. But an investigation into RNA splicing showed that there was no protein involved in cutting introns out of hnRNA (pre-RNA). In fact, the molecule responsible for breaking the phosphodiester bonds was snRNA (small nuclear RNA). snRNA and associated proteins are together called snRNPs (snurps), which gather in a spliceosome. The hnRNA is fed through the spliceosome and the snRNA breaks and reattaches bonds. From this point on, it was clear that ribonucleic acids could act as enzymes, and proteins were not alone. Enzymes that are ribonucleic acids are referred to as ribozymes.

Answer 2

Yes they are all majorly proteins (some are RNA). Enzyme can speed up a biochemical reaction by lowering the activation energy. substrate binds to the enzyme active site for the conversion into product. The interactions are specific.

Answer 3

Yes, all enzymes are proteins. Enzymes are biological catalysts that accelerate chemical reactions in the body, and they are typically made up of amino acids arranged in a specific sequence to create a functional protein structure.

Answer 4

yes all enzymes are proteins (except a few RNA enzymes) and the reverse is not true. Enzymes play a vital role in biochemical catalysis. protease, lipase, amylase, nucleases are some enzymes.
