(I) Hormones are the protein-based chemicals secreted by the endocrine glands.

Question

(II) Enzymatic proteins decelerate the metabolic activity in the cells.
(III) Transport proteins are structurally associated with nucleic acids, either DNA or RNA. Nucleoprotein is an example of the genetic protein.

which two or one is true?

Answer 1

Let's evaluate each statement for accuracy:

(I) Hormones are the protein-based chemicals secreted by the endocrine glands.
- This statement is partially true. Hormones can be protein-based (e.g., insulin), but not all hormones are protein-based. Some hormones are steroid-based or derived from amino acids. Therefore, saying that all hormones are protein-based is not entirely correct.

(II) Enzymatic proteins decelerate the metabolic activity in the cells.
- This statement is false. Enzymatic proteins, or enzymes, typically catalyze and accelerate metabolic reactions, not decelerate them. They lower the activation energy required for reactions, thereby increasing the rate of metabolic processes.

(III) Transport proteins are structurally associated with nucleic acids, either DNA or RNA. Nucleoprotein is an example of the genetic protein.
- This statement is misleading. Transport proteins primarily function to move molecules across cell membranes and are not typically associated with nucleic acids. Nucleoproteins, on the other hand, are proteins associated with nucleic acids (DNA or RNA) and are involved in the structural organization of genetic material, but they are not classified as transport proteins.

Given the evaluation:

- None of the statements are completely true.
- Statements (I) and (III) have elements of truth but are not entirely accurate.
- Statement (II) is false.

So, none of these statements are fully true.
