Multiple Choice

Which of the following is NOT true regarding target cells in cell communication?

Target cells always respond to signaling molecules by increasing their metabolic rate.

Target cells have specific receptors for signaling molecules.

Target cells can alter their behavior in response to signaling molecules.

Target cells can respond to multiple types of signaling molecules simultaneously.

Verified step by step guidance

Identify the role of target cells in cell communication. Target cells are cells that have specific receptors for signaling molecules, allowing them to respond to these signals.

Understand that target cells can alter their behavior in response to signaling molecules. This means they can change their function or activity based on the signals they receive.

Recognize that target cells can respond to multiple types of signaling molecules simultaneously. This allows them to integrate different signals and coordinate complex responses.

Consider the statement that target cells always respond to signaling molecules by increasing their metabolic rate. Evaluate whether this is a universal response or if target cells can have varied responses depending on the signal.

Determine which statement is NOT true by comparing it to the known characteristics of target cells. The statement that does not align with the established understanding of target cell behavior is the one that is NOT true.
