Which of the following statements about proteins is true?
- A
All proteins are enzymes
- B
All proteins have catalytic properties.
- C
Proteins that are enzymes speed up chemical reactions dealing with the transformation of energy.
- D
The 20-odd amino acids are synthesized from proteins.
- E
DNA and RNA are highly structured proteins.
Enzymes are a type of protein that acts as a biological catalyst, speeding up chemical reactions in cells. They are involved in various cellular processes and are crucial for the transformation of energy and the regulation of metabolic pathways. The other statements are incorrect
Not all proteins are enzymes. Proteins have diverse functions in the body, including structural, transport, signalling, and regulatory roles, in addition to enzymatic functions.
While enzymes are proteins with catalytic properties, not all proteins have catalytic properties. Proteins can have various functions beyond catalysis.
Enzymes are a type of protein that acts as a biological catalyst, speeding up chemical reactions in cells. They are involved in various cellular processes and are crucial for the transformation of energy and the regulation of metabolic pathways.
Amino acids are the building blocks of proteins. Proteins are synthesized from amino acids, not the other way around.
DNA and RNA are nucleic acids, not proteins. They are distinct types of biomolecules that have roles in genetic information storage and transfer, but they are not proteins.
