- 27. Explain the full signal transduction mechanism for intracellular-mediated responses (the actions of lipophilic hormones).(60). A 3 year old boy is evaluated because he had recurrent episodes of otitis media, an episode of pneumonia, and chronic diarrhea since he was 6 months of age.His height is in the 10th percentile and his weight is in the 8th percentile. Serum IgM concentration is increased and serum IgG, IgA and IgE concentrations are markedly decreased. Which of the following molecules is most likely deficient in this patient? (A) C1 inhibitor (B) C8 (C) CD 40 ligand (CD 154) (D) interleukin-2 (IL-2) receptor gamma chain (E) NADPH oxidasPlease ASAP. Thank you. What happens when Gαq proteins are stimulated?

Explain the roles of GEFs and GAPs in their activation/inactivation?how does covid19 affect the systems of the body.. for example, nervous system, excretory system, endocrine system?
- What does the fact that the two histograms overlap as much asthey do indicate about the extent to which PCSK9 determinesplasma LDL cholesterol levels?Describe the handling of Ca21 by the kidneys and gastrointestinaltract?6. Increasing the aldosterone secretion during prolonged muscle activity in hot weather allows you to compensate for the sodium loss in sweat and remove the accumulated excess of potassium. Explain these biological effects of the hormone during exercise. For answer: „Total Signal transduction starting with hormon recopios, e) explain the role of the hormone in the regulation of gene transcription and translation; d) describe the role of proteins that have their synthesis regulated by aldosterone.
- Describe the mechanism of hormone response resulting from the binding of a hormone with an intracellular receptor.A scientific study demonstrated that rat mothering behavior impacts the stress response in their pups. Rats that were born and grew up with attentive mothers showed low activation of stress-response genes later in life, while rats with inattentive mothers had high activation of stress-response genes in the same situation. An additional study that swapped the pups at birth (i.e., rats born to inattentive mothers grew up with attentive mothers and vice versa) showed the same positive effect of attentive mothering. How do genetics and/or epigenetics explain the results of this study?The same second messengers are used in many different cells, but the response to second messengers is different in each cell. How is this possible?
