|
Estrogen is produced in very large concentration and therefore diffuses widely.
|
|
|
Estrogen has specific receptors inside several cell types, but each cell responds in the same way to its binding.
|
|
|
Estrogen binds to specific receptors inside many kinds of cells, each of which have different responses to its binding.

Detailed explanation-1: -D) Estrogen binds to specific receptors inside many kinds of cells, each with different responses. At puberty, an adolescent female body changes in both structure and function of several organ systems, primarily under the influence of changing concentrations of estrogens and other steroid hormones.
Detailed explanation-2: -The rise in gonadotropins during puberty stimulates the ovary to produce estradiol, which is responsible for developing secondary sexual characteristics such as thelarche, growth of reproductive organs, fat redistribution to the hips and breasts, and bone maturation.
Detailed explanation-3: -At puberty the hypothalamic pituitary unit begins to function like that of an adult. The hypothalamus begins to secrete increased amounts of gonadotropin-releasing hormone or GnRH in a pulsatile manner and the pituitary responds by secreting increased amounts of gonadotropins, FSH and LH in a pulsatile manner.
Detailed explanation-4: -testosterone – a hormone produced by the testes which controls the development of male secondary sexual characteristics, for example, facial hair. oestrogen – a hormone produced by the ovaries which controls the development of female secondary sexual characteristics, for example breast development.
Detailed explanation-5: -How can one hormone, such as estrogen, mediate so many effects? Estrogen binds to specific receptors inside many kinds of cells, each with different responses. Hormones are chemical substances produced in one organ that are released into the bloodstream and affect the function of a target organ.
