Verified step by step guidance

Understand that cell signaling is a fundamental process that enables cells to communicate with each other, which is crucial for maintaining homeostasis and coordinating various cellular activities.

Recognize that cell signaling involves the transmission of signals from one cell to another, often through signaling molecules such as hormones, neurotransmitters, or cytokines.

Identify that the process of cell signaling typically involves three main stages: signal reception, signal transduction, and cellular response.

Acknowledge that cell signaling is not directly responsible for ATP production, DNA replication, or the breakdown of cellular waste, but rather facilitates communication and coordination between cells.

Conclude that the correct description of cell signaling is that it allows cells to communicate and coordinate their actions, which is essential for the functioning of multicellular organisms.
