Intra + extra cellular

• What are intracellular enzymes?

  Proteins that function within their producing cells
• Where are intracellular enzymes typically located?

  Within specific organelles like mitochondria
• What is the primary function of intracellular enzymes?

  To maintain cellular homeostasis by catalyzing reactions
• What factors affect the activity of intracellular enzymes?

  pH, temperature, inhibitors, and activators
• What are the functions of intracellular enzymes?

  • Metabolic pathways
  • Genetic processes
  • Signal transduction
  • Detoxification
• How do intracellular enzymes exhibit substrate specificity?

  They are specific to substrates and catalyze reactions
• What is an example of an intracellular enzyme?

  Catalase
• Where is catalase located and what is its function?

  Located in cytoplasm; breaks down hydrogen peroxide
• Why is catalase important for cells?

  It protects the cell from oxidative damage
• What are the key characteristics of extracellular enzymes?

  • Secretion outside cells
  • Specificity
  • Role in digestion and absorption
  • Breakdown of complex molecules
• What is the definition of extracellular enzymes?

  Enzymes that work outside of their producing cells
• What role do extracellular enzymes play in saprophytic feeding?

  They break down large molecules for nutrients
• What is an example of an extracellular enzyme?

  Amylase
• What is saprophytic feeding?

  • Process by which organisms obtain nutrients
  • Involves excreting extracellular enzymes
  • Nutrients sourced from dead or decaying organic matter
• What are the key characteristics of saprophytic feeding?

  • External digestion
  • Absorption of nutrients
  • Decomposer role in ecosystems
• What is the role of saprophytic organisms in ecosystems?

  They act as decomposers
