Question
Chapter 9.5, Problem 2EQ
Summary Introduction
To determine: Whether prednisolone inhibits the ability of rats to make their own ACTH when they were injected with both prednisolone and ACTH.
Introduction: In the process of apoptosis, first the cell shrinks and the destruction of internal structures like nucleus and cytoskeleton begins which results in the cell to become round shaped. Then plasma membrane forms irregular extensions which result in breaking as small fragments

What is the effect of marijuana in animals?
Long-term methamphetamine use leads to changes in the brain. Think about how methamphetamine changed where dopamine was found in the cell. What are some changes that you might expect based on this simulation?
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?
Group of answer choices
Glucagon: stimulates the activation of the mitogen activated protein (MAP) kinase pathway
Nitric oxide (NO): must bind to its target protien withn a few seconds because NO degrades rapidly
Steroid hormone: produces a response in its target cells within seconds
Acetylcholine: hydrophobic molecule that binds to…

- When the neurotransmitter acetylcholine (ACh) binds the acetylcholine receptor (a GPCR) on muscle cells, it causes them to contract. ZIGGY, a chemical analog of ACh, also binds to the same acetylcholine receptor on muscle cells, but instead causes the muscle cells to relax. For this reason, it is sometimes prescribed as a muscle relaxer. Explain in 3-4 sentences how ZIGGY could cause muscle relaxation. How can both ZIGGY and ACh bind the same GPCR? And then how can they have different effects on the cells, despite binding to the same receptor on the same cells?arrow_forwardOrganophosphate poisoning is a result of excess acetylcholine at different nerves and receptors in the body because acetylcholinesterase is blocked. Please provide rational to explain how the binding of organophosphate with serine in the acetylcholinesterase enzyme leads to excess accumulation of acetylcholine.arrow_forwardThe drug Celebrex selectively inhibits PTGS2 while aspirin and other NSAID’s inhibit both PTGS1 and PTGS2 in the same way.

- 30. Let's consider the pups of that new rat mom. If her behavior is changed as a result of an oxytocin infusion, what effect would this likely have on the hippocampi of the pups? a. Increased production of glucocorticoid receptors, leading to worse control of the stress response b. Decreased production of glucocorticoid receptors, leading to better control of the stress response c. Decreased production of glucocorticoid receptors, leading to worse control of the stress response d.

- Dopamine, epinephrine (or norepinephrine) and histamine are important neurotransmitter agonists. When these ligands interact with their cellular receptors, how do they mainly elicit their responses? Choose the correct answer(s) and explain why. a) Activate adenylyl cyclase directly, leading to increased intracellular cAMP levels b) Activate phospholipase C c)Induce or inhibit synthesis of ligand specific intracellular proteins d) Open or close ligand gated ion channels e) Regulate intracellular second messengers through G-protein-coupled receptorsarrow_forwardDesign a novel drug for treatment for overactive bladder syndrome which does not target the muscarinic M3 receptors directly, but rather targets one of the second messenger signalling molecules within the smooth muscle cells as a result of muscarinic M3 receptor activation. Which second messenger molecule would you choose to target? Justify your choice and explain how targeting this second messenger pathway would result in the reduction of bladder smooth muscle contraction.arrow_forwardMost of the short-term physiological responses of cells to cAMP are mediated by activation of PKA. Another common second messenger is cGMP. What are the targets of cGMP in rod and smooth muscle cells?arrow_forward
- Suppose that two different organs, such as the liver and heart, are sensitive to a particular hormone (such as epinephrine). The cells in both organs have identical receptors for the hormone, and hormone-receptor binding produces the same intracellular second messenger in both organs. However, the hormone produces different effects in the two organs. Explain how this can happen.arrow_forwardOrganophosphate poisoning is a result of excess acetylcholine at different nerves and receptors in the body because acetylcholinesterase is blocked. Please provide rational to explain how the binding of organophosphate with serine in the acetylcholinesterase enzyme leads to excess accumulation of acetylcholine.arrow_forwardRecent research showed that glucocorticoid receptor expression increased in rat hippocampus follow their exposure to loud noise.
