<p></p><hr/><p>1. Insulin is a lipid hormone secreted by the stomach</p>

<p></p><p>2. Growth hormone is a lipid hormone&nbsp;</p>

<p></p><p>3. Insulin receptors are located inside the mitochondria of cells</p>

<p></p><p>4.&nbsp;Hyper-secretion of growth hormone may lead to dwarfism</p>

<p></p><p>5. Growth hormone is secreted by the pituitary gland &nbsp;&nbsp;</p>

<p></p><p>6. Insulin receptors are located on cell membranes</p>

<p></p><p>7. Both growth hormone and insulin are protein hormones and thus can be produced by means of biotechnology.</p>

<p></p><p>8.Insulin causes cells to glucose &nbsp;&nbsp;&nbsp;&nbsp;</p>

<p></p><p>9. Insulin is a hormone secreted by the adrenal cortex&nbsp;</p>

<p></p><p>10. When a person intakes a large quantity of sugar, the pancreas will respond by secreting insulin</p>

<p></p><p>And which are secreted by the posterior pituitary</p>

<p></p><hr/><p>What is the &nbsp;&nbsp;</p>

<p></p><p>Which gland secretes epinephrine and norepinephrine</p>

<p></p><p>Hormones from this gland help regulate metabolism of Carbohydrates, lipids and proteins</p>

<p></p><hr/><p>Which gland helps to regulate circadian rhythms</p>

<p></p><p>Which gland secretes cortisol and aldosterone</p>

<p></p><p>This hormone is called a mineralcorticoid because it helps regulate the concentration of mineral electrolytes, such as sodium and potassium ions.</p>
