any cell that has receptor for a specific chemical signal is called a target cell.
during cell signalling the cell which produces the signal is called signaling cell while the cell which respond to the signal is called target cell.
Question 16 Any cell that has receptors for a specific chemical signal is called a(n) cell....
Question 26 2.2 p The phosphorylation of specific amino acids is a characteristic of the cell producing the ligand. e a class of GTP G-protein signal receptors. secondary messengers. receptor tyrosine kinases. transcription factors. Signal transduction is initiated O when the chemical signal is released from the signaling cell. o when the signal molecule alters the receptor protein in some way. o after the target cell divides. after the ligand is degraded. o when the receptor protein is synthesized.
1. Any compound, either natural or synthetic, that stimulates specific receptors is called an (agonist/antagonist). Which is correct?
D Question 22 2.2 pts In the process of cell signaling, the signaling molecule that is specifically detected by the target cell o is called a signal transducer. o is called a polymer is known as a secondary messenger. is called a ligand. e terminates the signal reception If phosphorylation were inhibited, this would most affect the activity of G-protein-linked receptors. e ligand-gated ion channels. transcription factors e phosphatase enzymes. O receptor tyrosine kinases.
Question (1 point) 1st attempt Which statement is true about cell-surface receptors? Choose one: O All extracellular signal molecules bind to a single type of receptor. O All cell-surface receptors bind to a single, unique extracellular signal molecule. O Each cell-surface receptor can bind to an endless variety of extracellular signal molecules. Some cell-surface receptors can bind to multiple signal molecules. O All drugs block the activation of ion-channel-coupled receptors. 11 OF 15 QUESTIONS COMPLETED 07/15 >

16)How can you show experimentally that that day-length signal is perceived by leaves? 17)What specific gene is induced as a result of day length? Wherein the plant this gene is activated? Then how does this gene activate other genes in the SAM? 18)Transition of SAM into inflorescence meristem is regulated by several genes. With known knowledge how do you explain what is happening during SAM to IM transition? 19)Using ABC model explain how the different structures are formed in developing...
