-Receptors

-Intracellular signal molecules

(a)  

Is cell communication contact dependent

• True

• False

Short-range signals happen by

• Traveling short distances

• travel long distance

• direct cell-cell contract

• released by a nerve cell > stimulate a target cell

Antigen presentation initiated by dendritic cells (DCs) or other antigen-presenting cells (APCs) leads to stimulation of T cells to produce cytokines

• True

• False

What are the two classes of signals

• To large or too hydrophilic to cross membrane

• Small enough or hydrophilic

• Small enough or hydrophobic

• to large or hydrophobic

Same signal molecule can not induce different responses in different target cells

• True

• False

An example of fast signaling is

(a)  

An example of slow signaling is
