|
What is autocrine signaling?
|
Where cells secrete molecules that bind to its own receptors.

|
Cancer uses what type of signaling?
|
Autocrine

Why is rapid turnover of signaling molecules important?
|
For quick adjustments

|
How does cell-surface receptors act as signal transducers?
|
Activated cell surface receptors trigger a phosphorylation cascade.
