Explanation Characters: Testosterone Hormones Paracrine Secondary sexual character To explain: The reason why testosterone can be considered both an endocrine and a paracrine secretion of the testes. Testosterone is a male reproductive hormone that is secreted by the testes, which acts as both paracrine and endocrine in function. Testosterone as paracrine in function: Hormones which exert their effect only at their vicinity of secretion site are termed as paracrine hormones. Testosterone secreted by the testes influences the sertoli cells inside the testes to produce spermatozoa, thereby the testosterone function as a paracrine hormone...

Glitazones reduce insulin resistance by binding to a transcription factor in adipocytes, thereby reducing thesecretion of fatty acids. Glitazones are taken orally (in pill form). Using pharmacokinetic modeling, deriveequations to describe how the concentration of glitazones varies in the plasma as a function of time. Yourequations should be of the form: dCglitazone /dt = something, or dMglitazone /dt = something. Your model shouldinclude three compartments: the gut, the plasma, and the fatty tissues. Make sure to include a diagram thatillustrates your thinking, state all assumptions, and define your variables. Do not solve the equations.
