Question
Chapter 23.2, Problem 8CC
Summary Introduction
To determine: The situation where it is advantageous for the body to secrete ACTH and β-endorphins.
Introduction: A signal transduction pathway includes a group of proteins and polysaccharides that carry the signals. The signals carried, leading to conformational changes that trigger a cascade of reactions leading to a cellular response.

The drug Celebrex selectively inhibits PTGS2 while aspirin and other NSAID’s inhibit both PTGS1 and PTGS2 in the same way. Why do you think researchers wanted to discover a selective inhibitor to PTGS2?
A male patient was admitted to hospital because his extremities were cyanotic (blue in colour) and he had some convulsions. His blood sugar levels indicated that he was hypoglycemic. The doctors initially gave him glucose intravenously as well as adding it to his diet, but his blood sugar level did not stabilize. However, when the doctors introduced glucagon, the blood sugar levels stabilized. The patient was diagnosed as having a deficiency in glucagon. Select the item below that describes an effect of this condition.
Select one:
a. The liver breaks down glycogen to glucose, increasing the blood glucose concentration.
b. The liver cannot break down glycogen to glucose, so the blood glucose remains low.
c. The adipose tissue breaks down fat to form glycogen, keeping blood glucose low.
d. The muscle cells cannot store glycogen, so the blood glucose remains high.
Peanut and tree allergies are on the rise in modern, industrialized countries. Exposure to a protein
in the nuts causes sensitive people to react with skin hives, reddened skin, breathing problems
including the closing of the throat (anaphylaxis), and even heart attack. Much like a mosquito bite
or other insect bite, this is all mostly due to the actions of one hormone in particular.
1) What hormone triggers this reaction?
2) Why does it cause swelling/closing of the throat/airways?
3) How does it change or impact the heart rate and/or blood pressure to life-threatening levels?

Recent studies show that children with autism tend to have low levels of oxytocin. Oxytocin nasal spray has been tried as a medical intervention. List two main functions of oxytocin in the body.arrow_forwardPositive feedback loops are used in chemical messaging in the body. Below is a list of steps that describe how a positive feedback system works in chemical messaging. The list is out of order. Placed the list in the proper order. 1. A sensor in a persons finger senses a change in the bloodstream. 2. The chemical messenger triggers the production of a specialized protein in the finger in response to the original signal. 3. A chemical messenger is released from the brain and travels to the finger. 4. As the specialized protein is made in the finger, it triggers the production of even more specialized protein. 5. The brain determines that conditions are no longer in homeostasis.arrow_forward

- Someone goes for a jog first thing in the morning and encounters a squadron of javelinas, causing a release of epinephrine. Some of this circulating epinephrine binds to a G-alpha-s coupled receptor (GPCR) on the surface of muscle cells. Which of the following would occur in the muscle cell as a result of this activation? Nitric oxide synthesis would increase. cyclic AMP (cAMP) activity would increase. Phospholipase C (PLC) would hydrolyze (cut) the molecule PIP2. The levels of adenylate cyclase activity would decrease. The levels of adenylate cyclase activity would decrease. Which ligand is CORRECTLY matched with its characteristic?
