Explanation:
Answer:
d. Estrogen will bind to a receptor protein that enters the nucleus and activates specific genes.
Explanation:
Estrogens are small lipophilic molecules synthesized from cholesterol. This steroid hormone (estrogen) is able to directly enter into the cell nucleus to bind with their corresponding receptors. Subsequently, estrogen-receptor binding stimulates these receptors to form dimeric structures that bind to DNA and thus activate gene expression. Estrogen receptors interact with DNA and activate gene expression through zinc finger domains composed of four (4) cysteine residues surrounding a zinc atom.
Answer:
It affects the oxygenation of the tissues in a negative way, that is, causing tissue hypoxias.
Explanation:
What will happen is that BPG, having a different relationship with deoxyhemoglobin, hemoglobin will not give oxygen to organs or tissues during glycolysis at times when the sympathetic nervous system is activated or even in the maintenance of physiological tissue vitality, therefore it will trigger a drop in the partial pressure of the gas both in the blood and in the tissues since they will be retained in the hemoglobin structure without being able to release it.
