Questions and Answers

What are the typical outcomes when a hormone binds to its receptor?

  • Change in membrane permeability, alteration of reaction rates, or production of a new molecule (correct)
  • Increase in cellular volume, activation of all enzymes, or halting gene expression
  • Stimulation of cell division, reduction in transport proteins, or degradation of proteins
  • Enhancement of receptor number, decrease in reaction rates, or production of lipids
  • How does a change in membrane permeability typically affect cellular functioning?

  • Leads to immediate cell death by disrupting the membrane structure
  • Controls the entry or exit of substances by adjusting transport protein numbers (correct)
  • Boosts protein production by altering mitochondrial function
  • Triggers uncontrolled cell division by increasing membrane rigidity
  • What is the primary mechanism through which altering reaction rates by hormones affects cellular processes?

  • Increasing or decreasing gene expression levels
  • Promoting or inhibiting cell division through membrane signaling
  • Activating or deactivating enzymes involved in metabolic reactions (correct)
  • Directly binding to DNA to control protein synthesis
