AP Bio Insta-Review Topic 4.1: Cell Communication

Front

What is autocrine signaling?

Back

A type of cell signaling where a cell secretes a signal that binds to receptors on its own surface, affecting its own activity.

Front

What is the location of receptors for protein hormones?

Back

Membrane Bound - Protein hormones bind to receptors located on the cell membrane.

Front

What role do glycolipids play in cell communication?

Back

Glycolipids aid in direct cell-cell communication by serving as recognition sites on the cell surface.

Front

Which organelle is responsible for producing endocrine signals?

Back

Rough Endoplasmic Reticulum (Rough ER) - It synthesizes proteins that can act as hormones.

Front

What is paracrine signaling?

Back

A type of signaling where a cell communicates with nearby cells through the release of signaling molecules.

Front

Define synaptic signaling.

Back

A form of communication in the nervous system where neurotransmitters are released from a neuron to communicate with another neuron or muscle cell.

Front

What is the difference between endocrine and exocrine signaling?

Back

Endocrine signaling involves hormones released into the bloodstream, while exocrine signaling involves substances released through ducts to the outside of the body or into the digestive system.

Front

What is the function of the cell membrane in cell communication?

Back

The cell membrane contains receptors that detect signaling molecules and facilitate communication between cells.

Front

What is a signaling molecule?

Back

A chemical substance that transmits information between cells, such as hormones, neurotransmitters, or growth factors.

Front

What is the role of the Golgi apparatus in cell signaling?

Back

The Golgi apparatus modifies, sorts, and packages proteins and lipids for secretion or delivery to other organelles.
