Question

Quizplus · Accepted Answer

Local and long-distance signals in cells can activate different signaling pathways that result in changes in metabolism, gene expression, growth, and development. Therefore, any of these choices can be triggered by cellular signals depending on the type, strength, and duration of the stimulus, as well as the cell type and context. For example, some signals may activate catabolic or anabolic pathways to generate or consume energy and nutrients, others may induce or repress transcription factors to regulate gene expression, and others may stimulate or inhibit cell proliferation, differentiation or apoptosis to affect growth and development. Thus, the specificity and diversity of signaling responses allow cells to adapt to internal and external cues and maintain homeostasis or respond to challenges.
