Back

Paracrine signaling

Front

What is the role of second messengers in cell communication?

Back

Relay a signal from the outside to the inside of the cell.

Front

Hormones are primarily involved in which type of signaling?

Back

Endocrine signaling

Front

What mechanism is commonly used for signal amplification in cells?

Back

An enzyme cascade.

Front

What is synaptic signaling?

Back

A form of communication between neurons where neurotransmitters are released across a synapse.

Front

Define endocrine signaling.

Back

A type of signaling where hormones are released into the bloodstream to affect distant target cells.

Front

What is the difference between autocrine and paracrine signaling?

Back

Autocrine signaling affects the same cell that releases the signal, while paracrine signaling affects nearby cells.

Front

What is the function of neurotransmitters?

Back

Chemicals that transmit signals across a synapse from one neuron to another.

Front

What is signal transduction?

Back

The process by which a cell responds to external signals through a series of molecular events.
