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.
Because cellulose is a complex polysaccharide which is essential in dietary functions. Since we don't have the enzymes that digest cellulose, it passes through our gut unchanged hence form an important roughage which aids in preventing constipation as well as smooth movements of our intestines.
Answer:
Null hypothesis: p= 0.65
Alternative Hypothesis: p < 0.65
Explanation:
Below are the null and alternative hypothesis,
Null hypothesis: p= 0.65
Alternative Hypothesis: p < 0.65
Test statistic for text of significance
z = (pcap –p)/ ![\sqrt{ [p*(1-p)/n]}](https://tex.z-dn.net/?f=%5Csqrt%7B%20%5Bp%2A%281-p%29%2Fn%5D%7D)
z = (0.576 – 0.65)/ ![\sqrt{[0.65×1-0.65)/125]}](https://tex.z-dn.net/?f=%5Csqrt%7B%5B0.65%C3%971-0.65%29%2F125%5D%7D)
z = 1.73
P- value Approach
p-value = 0.0414
As P-value < 0.05, we reject the null hypothesis
There is sufficient evidence to conclude that the mother consumed vitamin D supplements during pregnancy. A researcher in a northern region felt that the percentage should be lower for this region because with reduced hours of sunshine during winter months, pregnant women tended to use of higher doses of supplements to compensate.
