Cells & Tissues

• What is a cell?

  The basic structural and functional unit of life
• What processes are cells capable of performing for survival?

  Physical and chemical processes necessary for survival
• What are the two phases of metabolism?

  • Anabolism (constructive phase)
  • Catabolism (destructive phase)
• What is anabolism?

  The constructive phase of metabolism
• What types of syntheses occur during anabolism?

  Carbohydrate, protein, lipid, and steroid syntheses
• Where do the syntheses of carbohydrates, proteins, lipids, and steroids occur?

  In the rough and smooth endoplasmic reticulum
• What is catabolism?

  The destructive phase of metabolism
• What process is involved in catabolism?

  Glycolysis and glycogen breakdown
• Where does glycogen breakdown occur?

  In the liver and skeletal muscle
• What hormone triggers glycogen breakdown to produce glucose?

  Glucagon
• How do anabolism and catabolism differ in metabolism?

  Anabolism builds molecules, catabolism breaks them down
