Why do hydrogen bonds rely on polar and covalent bonds

Medicine
1 answer:
Yuki888 [10]3 years ago
3 0

Hydrogen bonds rely on polar and covalent bonds because the hydrogen will have a very slight positive proton charge because of the negative electrons being pulled more towards the other element. Because of this proton positive charge, the hydrogen will be attracted to other electronegative charges. This is information on a polar covalent bond. This explains why this is really reliable for hydrogen's usage.

Which of the following target cells to increase metabolism? (Choose two)
xz_007 [3.2K]

Answer:

Hormones that act on the target cells to increase metabolism are Triiodothyronine (T₃) and Thyroxine (T₄).

Explanation:

The hormones triiodothyronine (T₃) and thyroxine (T₄) are the active forms of thyroid hormone, responsible for increasing cell metabolism.

Both T₃ and T₄are produced by the thyroid gland, in response to the pituitary hormone TSH. T₄ is more abundant but less powerful than T₃

Thyroid hormones are responsible for controlling cell metabolism, since their increase determines an increase in metabolism, and their deficiency slows it down.

The other options are not correct because:

  • <em><u>Thyrotropin Releasing Hormone (TRH)</u></em><em> is produced by the hypothalamus to activate the production of TSH in the pituitary gland.</em>
  • <em><u>Thyroid Stimulating Hormone (TSH)</u></em><em> is a pituitary hormone in charge of activating the production of T₃ and T₄ in the thyroid.</em>
  • <em><u>Adrenocorticotropic Hormone (ACTH)</u></em><em> is produced by the pituitary gland to stimulate the production of hormones in the adrenal cortex.</em>
