Steroid hormones pass through the cell membrane and bind to a specific steroid hormone receptor protein. The combined steroid and receptor protein then bind to a specific sequence of bases in the DNA molecule. This sequence of bases is part of the promotor of a gene. Binding of the steroid - receptor complex either activates (switches on) or represses (switches off) the gene which is controlled by that promotor. If the gene is switched on then it will produce mRNA (transcription) which will lead to the sysnthesis of protein (translation). If the gene is switched off then mRNA will not be produced and no protein will be synthesised. In summary, steroid hormones can act to operate 'switches' for genes, switching protein synthesis on or off.

Where does the protein synthesis take place?
On the ribosomes in the cytoplasm of the cellRibosomes
Why is protein synthesis important?
Protein synthesis-growth====its the process in how we grow, how characteristics are brought out in us e.g. an enxyme in your stomach digests protein. If protein synthesis didnt produce this we wouldntdigest protein. Same goes for everythng else.
How can mutations affect protein synthesis?
it can cause cancer
Where in a cell does protein synthesis take place?
In cells protein is made when the cells mate and then the synthesis takes place. It takes place in the mitochondria.
Where does ribosome synthesis take place?
Ribosomal-based protein synthesis takes place in the cytoplasm of the cell. Peptides are synthesized by the ribosomes, typically on the rough ER of the cell.
What is specific function of t3 thyroid hormone?
T3 and T4 hormones regulate the metabolism, protein synthesis and sensitivity to other hormones in the body.
What hormones increase protein synthesis?
Growth hormone
What is triiodothyronine?
When the thyroid receives thyroid stimulating hormone (TSH) from the pituitary gland it produces triiodothyronine which is commonly referred to as T3. This hormone helps to regulate the metabolism, protein synthesis and sensitivity to other hormones in the body.When the thyroid gland receives thyroid stimulating hormone (TSH) from the pituitary gland it produces triiodothyronine, which is commonly referred to as T3. This hormone helps regulate the metabolism, protein synthesis and sensitivity to other hormones in the body.
What plays a role in synthesis of steroid based hormones and protein?
The Smooth endoplasmic Reticulum, catalyze reactions involved with: synthesis of steroid based hormones like sex hormones.
Which hormone does the thyroid secrete?
When the thyroid receives thyroid stimulating hormone (TSH) from the pituitary gland it produces triiodothyronine which is commonly referred to as T3, and thyroxine which is commonly referred to as T4. These hormones regulate the metabolism, protein synthesis and sensitivity to other hormones in the body. Known as one of the body's master glands, the thyroid's primary purpose is to produce hormones. When the thyroid receives thyroid stimulating hormone (TSH) from the pituitary gland it produces triiodothyronine which is commonly referred to as T3, and thyroxine which is commonly referred to as T4. These hormones regulate the metabolism, protein synthesis and sensitivity to other hormones in the body.
What does triiodothyronine and thyroxine do?
When the thyroid receives thyroid stimulating hormone (TSH) from the pituitary gland it produces triiodothyronine which is commonly referred to as T3, and thyroxine which is commonly referred to as T4. These hormones regulate the metabolism, protein synthesis and sensitivity to other hormones in the body.
Thyroxine and triiodothyronine are synthesized in the thyroid gland from?
When the thyroid receives thyroid stimulating hormone (TSH) from the pituitary gland it produces triiodothyronine which is commonly referred to as T3, and thyroxine which is commonly referred to as T4. These hormones regulate the metabolism, protein synthesis and sensitivity to other hormones in the body.
What is the mechanism of action of lipid soluble hormones?
activation of mRNA, which increases protein synthesis in the cell
What part of the brain regulates the secretions of the anterior pituitary gland?
When the thyroid receives thyroid stimulating hormone (TSH) from the pituitary gland it produces triiodothyronine which is commonly referred to as T3, and thyroxine which is commonly referred to as T4. These hormones regulate the metabolism, protein synthesis and sensitivity to other hormones in the body.
How do cells regulate synthesis to conserve energy?
how do cells regulate synthesis to conserve energy
Why do the body need protein synthesis while the body is also synthesis protein?
why does the body need protein synthesis while the also synthesis protein?
What is the product of protein synthesis?
A protein. That's what protein synthesis means.
