Reception

Part A
Correct
This receptor is not associated with the plasma membrane.
Part B
Correct
This is a G-protein-linked receptor.
Part C
Correct
This is a receptor tyrosine kinase.
Part D
Correct
This receptor does form a channel.
Part E
Correct
The binding of signal molecules to tyrosine-kinase receptors activates tyrosine-kinase enzymes, which phosphorylate tyrosines.
Part F
Correct
This is an ion-channel receptor.
Part G
Correct
Nonpolar molecules can diffuse through the plasma membrane and bind to intracellular receptors.
Part H
Correct
Steroids bind to intracellular receptors, which can then bind to, and regulate, the expression of genes.
Part I
Correct
Steroids are nonpolar and can diffuse through the plasma membrane.
Part J
Correct
Thyroid hormones are able to pass through the plasma membrane.
