Cell Communication Flashcard

Front

What do protein kinase molecules do to other molecules?

Back

They add a phosphate group to them.

Front

What is a molecule that specifically binds to another molecule called?

Back

Ligand.

Front

An example of DIRECT cell communication is:

Back

White blood cells bumping into each other sharing antigen info.

Front

In the scenario, which part represents transduction? Julian called Kirani to tell her that several people need to put flyers up for an upcoming event. Kirani told Taylin about it who walked over to Makoriyae to tell him about the plan. Makoriyae then got Ava, Marquize, and Sophia to hang up the flyers for the event.

Back

Kirani relaying the message to Taylin and Taylin telling Makoriyae.

Front

What type of feedback loop is shown?

Back

Positive.

Front

Define cell communication.

Back

The process by which cells send and receive signals to coordinate their functions.

Front

What is a ligand?

Back

A molecule that binds specifically to another molecule, often a receptor.

Front

What role do hormones play in cell communication?

Back

Hormones act as signaling molecules that travel through the bloodstream to target tissues.

Front

What is the difference between direct and indirect cell communication?

Back

Direct communication involves physical contact between cells, while indirect communication involves signaling molecules.

Front

What is signal transduction?

Back

The process by which a cell converts an external signal into a functional response.
