The first time an organism comes into touch with a specific antigen, it produces effector T and B cells, which are activated cells that protect against the pathogen. A initial immune response is the creation of these effector cells as a result of the first encounter. When the same pathogen enters the organism again, memory T and memory B cells are created.

All steroid hormones are synthesized from the amino acid tyrosine.
a. True
b. False

Answers

It is false that all steroid hormones are synthesized from the amino acid tyrosine.

Although certain water-soluble hormones, including such thyroid hormone and some catecholamines, be formed from the amino acid tyrosine, the bulk of steroid hormones (lipid-soluble) such as estrogen and testosterone are created from cholesterol molecules. Steroid hormones are generated from cholesterol and are created in the adrenal cortex, gonads, and placenta. Many are clinically important. The mitochondria & smooth endoplasmic reticulum are responsible for the synthesis of steroid hormones.

Since they are lipophilic, they could not be kept in vesicles from where they would quickly diffuse and are thus generated as precursors as needed. Steroid hormone precursors are transformed to active hormones upon stimulation of the parent cell and disperse from the parent cell by simple diffusion when their intracellular concentration rises. All steroid hormones are insoluble in plasma as well as other bodily fluids because they are produced from cholesterol. As a result, steroids are attached to transport proteins, which extends their half-life and ensures their widespread dispersion.
