Chapter 37: Q.15 (page 1078)

A rise in blood glucose levels triggers release of insulin

from the pancreas. This mechanism of hormone

production is stimulated by:

a. humoral stimuli

b. hormonal stimuli

c. neural stimuli

d. negative stimuli

Short Answer

Expert verified

A rise in blood glucose levels triggers the release of insulin from the pancreas. This mechanism of hormone production is stimulated by humoral stimuli. Hence, the correct option is 'a'.

Step by step solution

01

Step 1. Introduction 

A humoral stimulus is a shift in extracellular fluids that regulates the release of hormones.

02

Step 2. Explanation of the correct option 

For instance, a spike in blood glucose levels causes the release of insulin from the pancreas. In a negative feedback loop, as blood glucose levels fall as a result of insulin, the pancreas is alerted to stop manufacturing insulin.

03

Step 3. Explanation of the incorrect options 

A hormone is released in response to another hormone, which is referred to as a hormonal stimulus. Some endocrine glands are induced to release hormones by hormones from other endocrine glands.

Neural stimuli are when the neurological system directly causes the release of hormones from the endocrine glands.

Name two important functions of hormone receptors.

When insulin binds to its receptor, the complex is
endocytosed into the cell. This is an example of ______ in
response to hormone signaling.
a. cAMP activation
b. generating an intracellular receptor
c. activation of a hormone response element
d. receptor down-regulation

A new antagonist molecule has been discovered that
binds to and blocks plasma membrane receptors. What
effect will this antagonist have on testosterone, a steroid
hormone?
a. It will block testosterone from binding to its
receptor.
b. It will block testosterone from activating cAMP
signaling.
c. It will increase testosterone-mediated signaling.
d. It will not affect testosterone-mediated signaling.

Heat shock proteins (HSP) are so named because they help refold misfolded proteins. In response to increased temperature (a

鈥渉eat shock鈥�), heat shock proteins are activated by release from the NR/HSP complex. At the same time, transcription of HSP

genes is activated. Why do you think the cell responds to a heat shock by increasing the activity of proteins that help refold

misfolded proteins?

A scientist hypothesizes that the pancreas鈥檚 hormone production is controlled by neural stimuli. Which observation would support this hypothesis?

a. Insulin is produced in response to sudden stress without a rise in blood glucose.

b. Insulin is produced in response to a rise in glucagon levels.

c. Beta cells express epinephrine receptors.

d. Insulin is produced in response to a rise in blood glucose in the brain.
