Answer:
Insulin is a protein hormone which binds to the membrane receptor where as steroid hormones bind to the intracellular receptors.
Explanation:
Hormones can be divided into two groups based on their binding with receptor. Some hormones are water soluble like protein or peptide hormone (example is insulin) and catecholamines. These water soluble hormones cannot cross the plasma membrane of the target cell and thus bind to the membrane receptor. Binding to the membrane receptor leads to activation of intracellular enzymes which bring the physiological change. Steroid hormones in the other case can cross the plasma membrane and then bind to the intracellular receptors. The hormone receptor complex then either binds or activates specific portion of DNA to bring the physiological change.
Insulin is made by beta cells islets of Langerhans in the pancreas. It controls the levels of glucose. It is a small protein made of two polypeptides, one of 21 amino acids and the other of 30 amino acids. These two are called A chain and B chain and are linked together by disulphide bonds. The pro-hormone contains an extra stretch called C-peptide. During the maturation process the proinsulin looses the c-peptide to become mature insulin protein hormone. An american company called Eli Lilly, for the first time made recombinant human insulin.
True inhibitory neurotransmitter would cause a signal to continue through a neuron
<span>The question says,'menstruation does not occur if the ............ The correct option is D. The uterine lining usually build up in order to serve as a bed and support for fertilized a egg. If fertilization does not occur, the uterine lining breaks down and come out as menstruation, but if fertilization occurs, then the uterine lining will not break down but will support the fertilized egg all through the pregnancy period.</span>
Answer: Integrins
Explanation: Integrins are proteins and are the principal receptors that attach the cell cytoskeleton to the extracellular matrix (ECM). Integrins by sense whether adhesion has taken place that is to say a cell can regulate the adhesive activity of its integrins from within.
