During phototransduction, the molecular processing in retinal rods under lightactivates mechanism to reduce cGMP that hyperpolarizes the cell. The correctsequence of cellular events is:activation of 11-cis-retinal --> activation of Transducin---> enzyme degradesCGMPactivation of Transducin --> opening of Na+ channel --> hyperpolarization of cellactivation of Transducin --> a photon induces 11-trans-retinal --> enzymedegrades CGMP0a photon induces 11-transretinal activation --> closing of Na+ channel -->hyperpolarization of cell

Cells become polarized through a process called polarization, which involves the localization of…

Many common medications function by interrupting the normal operation of certain signal transduction pathways. Which of the following describes a possible mechanism by which a certain medication may interrupt a signal transduction pathway? A A medication enters the target cell and triggers apoptosis by causing the release of di- gestive enzymes from cell lysosomes. B A medication interacts with the phospholipid bi-layer of the cell membrane and in- creases its permeability. с D A medication binds to membrane-bound glucose proteins and acts as an allosteric in- hibitor that prevents the intake of glucose by the cell. A medication diffuses through the membrane of a target cell and inhibits an enzyme that normally synthesizes a second messenger.
in. What order did these happen? all trans retinal induces conformational change in Rhodospin transducin is activated PDE hydrolyzes cGMP phosphadiesterase is activated nucleotide gated in a plus and CA plus channel closes

Describe how a signal is transmitted from the surface to the nucleus both generally (for any type of signal), and also specifically for the Notch pathway.
When a signal binds to the Tyrosine kinase receptor (RTK), you have studied that a list of events occur sequentially. Map the events in the correct order from 1st to the last step.

What is transmitter gated ion channels? What is their purpose?
Cyclin-dependent kinases are a type of "microchip" protein that require multiple inputs (i.e., structural alterations) to be activated-- and thus are active only under specific conditions (as shown in the diagram below). How does limiting activity to when all conditions have been met help the cell function properly? INPUTS has this phosphate been removed? been added? has this is cyclin present? phosphate
Cholera toxin has which of the following direct or indirect actions: a. opens Na+ channels; Choose all that apply; Group of answer choices closes Cl− channels increases cAMP levels activates αs subunit of GTP-binding protein increases GTPase activity
What is the actual “signal” that is being transduced inany signal transduction pathway, such as those shownin Figures 11.6 and 11.10? In what way is this information being passed from the exterior to the interior ofthe cell?
During development, two neuronal axons can have different migration paths through the same brain area because the growing axons have receptors for different guidance molecules. O one of the migrating axons can only respond to long-range guidance molecules. the migrating axons have different cytoskeletal organizations in them. that brain area has only long-range guidance molecules. that brain area has only short-range guidance molecules.
