- compare and contrast how GPCRs and RTKs transduce their signal to the cell? include the types of ligands they bind, the GTP binding protein that is activated, and how the signal is transduced and amplified. what effects does it have on the cell?arrow_forwardFor cellular transduction, why is it useful that phosphorylation cascades have a series of protein kinases? a. they amplify the original signal b. they always lead to the same cellular response c. the number of molecules used is small and fixed d. they are cell specificarrow_forwardWhich is true about signaling receptors? They are transmembrane proteins that have binding sites for extracellular activated proteinsto effect changes inside the cell. They are transmembrane proteins that have binding sites for extracellular DNA-binding proteins to effect changes inside the cell. They are transmembrane proteins that have binding sites for extracellular enzyme effectors to effect changes inside the cell.

- Describe several specific examples of signaling pathways (celll cell communication)in animals and plants in developmental biologyarrow_forwardWhere in a cell would you find signal receptors? What happens when a lipid-soluble signaling molecule binds its receptor?arrow_forwardHow could we promote rapid or slow signaling for medical purposes? So there are many examples of slow and rapid signaling via coupled receptors. For an example, salivary gland secretion is rapid signaling and cell growth is slow signaling. These pathways could be twisted and used to resolve medical issues in a more natural and less damaging way. Are there any experiments that have or could be done to test out promoting rapid signaling to speed up slow processes such as cell growth in a severe wound? What experiments have or could be done to test out slowing down signaling that is fast like cells responding to their environment negatively (over-active allergies)? Thank you.arrow_forward
- All cells of a multicellular organism may not respond in the same wayto a particular ligand (signaling molecule) that binds to a cell surfacereceptor. The difference in response may be due toa. the type of receptor for the ligand that the cell expresses.b the affinity of the ligand for the receptor in a given cell type.c. the type of signal transduction pathways that the cell expresses.d. the type of target proteins that the cell expresses.e. all of the above.arrow_forwarda universal feature of cell signaling receptors is that they? a. undergo a structural (shape) change when the signal molecule is bound b. are present only in the plasma membrane c. are only ion channels d. are protein kinases e. aer only nuclear receptorsarrow_forwardConcept test: Please discuss thoroughly. One of the key components in vertebrate limb development is the polarizing region, also known as the zone or polarizing activity of ZPA. Where in the limb bud is this region? What axis of the limb does it help to specify? What properties of this region make it an organizing region Through which signaling molecule does it exert its effects? What is the evidence for the importance of this molecule?arrow_forward

The fragment binds to receptor proteins on nearby cells and activates signaling pathways resulting in altered gene expression patterns in the cells. What form of intercellular signaling does this represent? Contact-dependent? Paracrine? Synaptic? Endocrine? Autocrine?arrow_forwardFill in the gap Although signal transduction pathways are modeled mostly by ----------, there are some underlying difficulties in the modeling. Therefore, it is necessary to develop -------- to capture the details of signaling pathways by exploiting high-throughput ------------arrow_forward
