Question

Choose the incorrect statement:

• A. Metabolic flux is the rate of turn over of molecules through a metabolic pathway
• B. Metabolites are converted into each other in a series of linked reactions called metabolic pathways
• C. Enzymes are organic catalysts that increase the speed of the reaction in biological systems
• D. Ribozymes are proteinaceous in nature

Answer 1

The correct option is D Ribozymes are proteinaceous in nature

Ribozymes are exceptions to proteinaceous enzymes. They are made up of nucleic acids. Ribozymes are RNA molecules capable of catalysing a biochemical reaction. Some ribozymes can be found in ribosomes where they function to link amino acids to form proteins. Ribonuclease P is an enzyme that can cleave other RNA molecules.
