What is cell communication?

Back

Cell communication refers to the various ways in which cells can send and receive signals to coordinate their functions and activities.

Front

What are ligands?

Back

Ligands are molecules that bind to specific receptors on target cells to initiate a response.

Front

What is the role of glycolipids in cell communication?

Back

Glycolipids are components of the cell membrane that facilitate direct cell-cell communication by serving as recognition sites.

Front

What is autocrine signaling?

Back

Autocrine signaling is 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 paracrine signaling?

Back

Paracrine signaling involves the release of signals by a cell that affect nearby target cells.

Front

What is endocrine signaling?

Back

Endocrine signaling involves the release of hormones into the bloodstream, which then travel to distant target cells.

Front

Where are steroid hormone receptors located?

Back

Steroid hormone receptors are located intracellularly, typically in the cytoplasm or nucleus.

Front

What is the function of the Rough Endoplasmic Reticulum (Rough ER) in cell signaling?

Back

The Rough ER is responsible for synthesizing proteins, including those that function as hormones in endocrine signaling.

Front

What is the difference between membrane-bound receptors and intracellular receptors?

Back

Membrane-bound receptors are located on the cell surface and bind to external signals, while intracellular receptors are located inside the cell and bind to signals that can cross the membrane.

Front

What is synaptic signaling?

Back

Synaptic signaling is a form of communication between neurons where neurotransmitters are released into the synaptic cleft to transmit signals to adjacent neurons.
