PBS 2.1: DIABETES

An organism's ability to stabilize its internal environment is called __________.

• negative feedback

• positive feedback

• homeostasis

• proprioception

This hormone, secreted by the beta cells of the pancreas, facilitates the uptake of glucose into cells:

• glucagon

• glycogen

• oxytocin

• insulin

The mechanism, where a physiological variable that is being monitored, triggers a response that counteracts the initial change.

• positive feedback

• homeostasis

• negative feedback

The disease in which the pancreas produces little or no insulin is:

• insulin resistance

• insulin sensitivity

• Type 1 diabetes

• Type 2 diabetes

A metabolic disorder with an increase in insulin resistance is:

• Type 1 diabetes

• insulin sensitivity

• insulin deficiency

• Type 2 diabetes

This loop system tends to magnify a bodily process or increase its output.

• homeostasis

• positive feedback

• negative feedback

• hormonal variance

Which of these would NOT be considered a therapeutic lifestyle change?

• losing bodyweight

• meditation and exercise

• drinking more water

• eliminating nicotine

• All are beneficial lifestyle changes

Growth, labor, blood clotting and menstruation are common examples of:

• negative feedback

• growth and development

• homeostasis

• positive feedback

Most loop systems in the body are positive feedback systems.

• true

• false

Insulin stimulates the storing of glucose in the liver as glucagon.
