Question

How does the steroid hormone influence cellular activities?
A. Changing the permeability of the cell membrane
B. Binding to DNA and forming a gene hormone complex
C. Activating cycle AMP located on the cell membrane
D. Using aquaporin channels as the second messenger

Answer 1

Hint: There are groups/combinations of cells that work together that are called a tissue. The cells interact with each other known as cellular activities that influence/put an impact on the steroid hormones as they enter inside the cell to show their effect.

Complete answer: Steroid hormones are the group of hormones that relate with the class of chemical compounds called steroids. There are three secretory glands which secrete the steroids namely-the adrenal cortex, testes, and ovaries-and during pregnancy by the placenta. All steroid hormones are taken from cholesterol. Many physiological processes are regulated by the steroid hormones, including the development and function of the reproductive system. The binding of a steroid hormone forms a hormone-receptor complex that affects gene expression in the target cell’s nucleus. The binding of a non- steroid hormone activates a secondary messenger that puts its effect on various processes inside the target cell. The steroid hormone then passes through the plasma membrane of a target cell and sticks to intracellular receptors which are present in the nucleus or the cytoplasm. The cell signaling pathways induced by the steroid hormones help to regulate the specific genes on the cell’s DNA. On the basis of their receptors, steroid hormones have been classified into five groups: Glucocorticoids, mineralocorticoids, androgens, estrogens, and progesterone.
Hence, the correct answer is option (B). Binding to DNA and forming a gene hormone complex.

Note: Steroids are very useful in the treatment of a variety of conditions in which the body’s defense system is malfunctioned and causes damage to the tissue. These are used as the main treatment for certain inflammatory conditions, such as myositis (inflammation of the muscle) and systemic vasculitis (inflammation of blood vessels).
