Chapter Questions
Which category of chemical signal (lipid or protein) relies on the process of signal transduction to move the message into the cell?
Why does the receptor have to be a transmembrane protein, instead of a surface protein?
Put the following steps of $\mathrm{G}$ protein-coupled receptor function in order:a. Cytoplasmic side of the receptor changes shapeb. G protein activates an enzyme on the inside of the cellc. Signal binds the receptord. G protein is activated
What is the purpose of the transduction step of signal transduction?
List the three stages of signal transduction.
As soon as a signal binds the receptor, what occurs to move the message into the cell?
Put the following steps of ligand-gated ion channel function in order:a. Second messengers rush into the cellb. Receptor gate opensc. Receptor is closedd. Signal binds the receptor
Which receptor type is key for nervous system function?
Protein kinase enzymes play an important role in signal transduction because they the message by creating a cascade.
