T/F: cytokines affect cells by entering through their plasma membrane
F: the cells they affect must have a specific receptor that they bind to
True. Cytokines are proteins that act as intercellular messengers, and they can bind to specific receptors on the surface of target cells. This binding triggers a signaling pathway that can lead to changes in gene expression, cell proliferation, differentiation, and other cellular responses. In order to bind to their receptors, cytokines must first cross the plasma membrane of the target cell, either by passive diffusion or with the help of membrane transporters.
