Q: Answer the following question given this paragraph: Adipose Tissue Adipose tissue produces and secretes several hormones involved in lipid metabolism and storage. One important example is leptin, a protein manufactured by adipose cells that circulates in amounts directly proportional to levels of body fat. Leptin is released in response to food consumption and acts by binding to brain neurons involved in energy intake and expenditure. Binding of leptin produces a feeling of satiety after a meal, thereby reducing appetite. It also appears that the binding of leptin to brain receptors triggers the sympathetic nervous system to regulate bone metabolism, increasing deposition of cortical bone. Adiponectinanother hormone synthesized by adipose cellsappears to reduce cellular insulin resistance and to protect blood vessels from inflammation and atherosclerosis. Its levels are lower in people who are obese, and rise following weight loss. Q: What type of tissue produces and secretes several hormones involved in lipid metabolism and storage? A:

Select from:
(a). hormonal tissue.
(b). metabolism tissue.
(c). somatic tissue.
(d). adipose tissue.
The answer is:
(d).
