Which of the following property/characteristic is incorrect about hormone?
High molecular weight
Non-nutrient chemicals
Chemical messengers
Regulatory activities
Endocrine glands create hormones, which are chemical messengers that are released into the bloodstream and travel to their intended organs and tissues to control a variety of physiological processes. Hormones are typically low molecular weight substances that can be categorised according to their chemical makeup into various groups, such as hormones generated from amino acids, peptide hormones, and steroid hormones. Hence option A is correct.
Because hormones are regulatory molecules rather than nutrients that give the body energy or building blocks, Option B, non-nutrient chemicals, is a true characteristic of hormones.
Because hormones are secreted by endocrine glands and function as chemical messengers to regulate a variety of physiological processes in the body, option C, messengers, is also a true characteristic of hormones.
Because hormones' primary purpose is to control the activities of various organs and tissues within the body, option D, regulatory activities, is also a valid characteristic of hormones.
