AP Cell Communication

Front

What is a ligand in cell communication?

Back

A ligand is a signaling molecule that binds to a receptor to initiate a cellular response.

Front

What is the role of a receptor in cell signaling?

Back

A receptor is a protein that receives and binds to signaling molecules (ligands) to trigger a response in the cell.

Front

What is apoptosis?

Back

Apoptosis is the process of programmed cell death that occurs in multicellular organisms.

Front

What is the first step of apoptosis?

Back

The first step of apoptosis is the destruction of the cell's DNA.

Front

What is signal transduction?

Back

Signal transduction is the process by which a cell converts an external signal into a functional response.

Front

What are the three main stages of cell signaling?

Back

The three main stages are reception, transduction, and response.

Front

What is paracrine signaling?

Back

Paracrine signaling is a form of cell communication where a cell produces a signal to induce changes in nearby cells.

Front

What is endocrine signaling?

Back

Endocrine signaling involves hormones being released into the bloodstream to affect distant target cells.

Front

What is autocrine signaling?

Back

Autocrine signaling occurs when a cell secretes a signal that binds to receptors on its own surface.

Front

What is synaptic signaling?

Back

Synaptic signaling is a type of communication that occurs between neurons at synapses, involving neurotransmitters.
