Questions and Answers

What is apoptosis?

  • Cell growth and proliferation
  • Uncontrolled and unregulated cell death
  • Coordinated and internally programmed cell death (correct)
  • Inflammation and tissue damage

In what process is apoptosis responsible for mediating cell death?

  • Hormone production and secretion
  • Cell growth and proliferation
  • Inflammation and tissue damage
  • Tissue development during embryo formation (correct)

How does apoptosis differ from necrosis?

  • Apoptosis is accompanied by inflammation and tissue damage
  • Necrosis is a controlled and regulated cell death
  • Apoptosis has regulated size of the cell turnover (correct)
  • Necrosis is involved in hormone-dependent tissues
