AP - Unit 2: Cell Communication

Front

What is phosphorylation?

Back

The process of adding a phosphate group to a molecule.

Front

What type of signaling is characterized by a cell signaling itself?

Back

Autocrine signaling.

Front

How is signal amplification most commonly achieved?

Back

Through an enzyme cascade.

Front

What type of signaling occurs over short distances between cells?

Back

Short distance signaling.

Front

What is the feedback mechanism called when a process enhances its own production?

Back

Positive Feedback Response.

Front

What is the role of hormones in cell communication?

Back

Hormones act as signaling molecules that facilitate communication between cells.

Front

What is the difference between autocrine and paracrine signaling?

Back

Autocrine signaling is when a cell signals itself, while paracrine signaling is when a cell signals nearby cells.

Front

What is a negative feedback loop?

Back

A process that counteracts a change, helping to maintain homeostasis.

Front

What is an example of long-distance signaling?

Back

Hormonal signaling through the bloodstream.

Front

What is the function of adenylyl cyclase in cell signaling?

Back

It converts ATP to cyclic AMP, a secondary messenger in signaling pathways.
