Final answer:
The process of signal integration involves the merging of signals from various cell-surface receptors, which results in an action from the cell. This integration is necessary for proper cellular response to stimuli and is processed in the central nervous system.
Step-by-step explanation:
Signals generated by receptors on the surface of a cell are integrated to determine the cell's actions through a process known as signal integration. In this process, the combination of signals from two or more different cell-surface receptors merge to activate a response in the cell. This ensures that the cell responds properly to its external environment. Sensory receptors play a crucial role in this by detecting stimuli and converting it into electrical signals that are transmitted to the central nervous system for processing.
The action potentials and graded potentials generated by stimuli allow for communication within neurons. These signals are then processed in the central nervous system where they can be integrated with other sensory information to produce a conscious perception that may result in a motor response. This intricate process allows for complex responses to a dynamic environment.
Therefore, the correct answer to the student's question on how signals are integrated and used to determine the cell's actions is c) The cell integrates the signals to make a decision. This integration of signals is a fundamental aspect of cellular communication and function.
