Question
Chapter 9.5, Problem 1EQ
Summary Introduction
To explain: The effect on apoptosis in the rat injected with salt water, prednisolone only, and prednisolone + ACTH or ACTH only.
Introduction: In the process of apoptosis, firstly the cell shrinks and destruction of internal structures like the nucleus and cytoskeleton begins. The cell becomes round shaped, and the plasma membrane forms irregular extensions, which break into small fragments

What is the relationship between the formation of
IP 3 and the elevation of intracellular [Ca²+]?
-/1
Binding of IP 3 to the membrane causes
releases of calcium.
Binding of IP3 to the smooth ER causes
releases of calcium.
Binding of IP3 to its receptor in bone
tissues triggers release of calcium.
None of these is the correct answer.

- NO answer needs more than 2 sentences, some require just a couple words. 7. GTP-y-s is an analog of GTP that cannot be hydrolyzed. How would you expect a Co-IP experiment between G-alpha and G-beta proteins to differ in the presence of GTP-y-a and GDP? 8. An epithelial cell line expressed a fluorescence-based cAMP biosensor in all cells, but only expressed a GPCR in ~30% of those cells. When you treated the cells with the GPCR ligand, fluorescence from the cAMP sensor immediately turned on in most cells (not just those expressing the GPCR). In one sentence suggest a simple explanation for why cAMP increased in non-GPCR-expressing cells. 9. Taxol is a drug that inhibits microtubule dynamics and is often used for cancer chemotherapy because it preferentially affects dividing cells. What microtubule-based structure is likely disrupted by Taxol so that it specifically affects proliferating cells? 10.

Which hypothesis regarding the effect of this mutation on EGF signaling is most likely to be correct? EGF signaling cascades would be active for longer in the cell. EGF signaling cascades would be active for a shorter period of time in the cell. EGF signaling cascades would not occur. EGF signaling would be unaffected.arrow_forward
- Three potential inhibitors for VEGF were discussed in the signal transduction simulation. Explain two possible steps that these drugs can be expected to interfere with VEGF signaling (Hint: think about the requirements for signaling to occur).arrow_forwardquestion: Summarize the following in concise and understandable language. Nanotechnology Tools to Inactivate SARS-CoV-2 in Patients The main target of SARS-CoV-2 is the respiratory tract (upper airways, lung), although other organs might also be infected (e.g., gut, kidney) and vasculature also appears to be a prime target. The expression of ACE2 probably determines uptake by different tissues. In addition to discussing immune-based approaches, because the lung is the most critically affected organ, we will center our discussion on the various options to inactivate the virus in the deep lung and to target the essential host cells for drug delivery. The virus reaches the alveoli and enters alveolar epithelial type II cells (AECII), due to the relatively high abundance of ACE2 and a permissive cellular milieu. These cells serve as a reservoir of the virus, which finally spreads throughout the lung, leading to the lung function impairment seen in severe cases. Airborne nanomaterials are…arrow_forward.
