Question

Put the following events in the correct order:

a. Chemical messenger binds to receptor on the target cell.
b. A response occurs in the target cell.
c. Chemical messenger is secreted.
d. Signal transduction occurs in the target cell.

Answer 1

The correct order of events is: (1) Chemical messenger is secreted, (2) Chemical messenger binds to receptor on the target cell, (3) Signal transduction occurs in the target cell, (4) A response occurs in the target cell. This sequence outlines the communication process between signaling cells and target cells through chemical messengers and signal transduction pathways.

Step-by-step explanation:

To put the following events in the correct order:

1. Chemical messenger is secreted.
2. Chemical messenger binds to receptor on the target cell.
3. Signal transduction occurs in the target cell.
4. A response occurs in the target cell.

The process described is a fundamental aspect of intercellular communication and involves the propagation of the signal through various stages. First, a signaling cell secretes a hormone or chemical messenger in response to a stimulus. Next, this messenger travels and binds to specific receptors on the target cell, which then initiates signal transduction. A complex signaling pathway or cascade unfolds, causing a series of intracellular events that lead to a cellular response. This is an example of how extracellular signals can impact cellular behavior and functions.
