Based on the information provided, a persistent and overactive transcription factor, resulting from a malfunction in a growth factor signaling pathway similar to Figure 11.15, would most likely lead to:

  • A: Increased breakdown of glycogen in liver cells.
  • B: A decrease in specific protein synthesis.
  • C: The prevention of signal reception at the cell surface.
  • D: Abnormal cell division and potentially cancer development.

Explanation

The text explicitly states: 'Malfunctioning of growth factor pathways like the one in Figure 11.15 can contribute to abnormal cell division and the development of cancer.' An overactive transcription factor would constantly stimulate gene expression related to growth and division, leading to uncontrolled proliferation.
