  1. Metabolism
    Catabolic reactions that break down large complex molecules for energy and smaller molecules
  2. Stages of metabolism
    • Stage 1: Digestion and hydrolysis break down molecules
    • Stage 2: Degradation
    • Stage 3: Oxidation of small molecules
  3. Cell Membrane
    • Separates the inside of cell from outside environment
    • Contains structure to communicate to other cells
  4. Cytoplasm
    All cellular content from nucleus to membrane
  5. Cytosol
    • Fluid part of cytoplasm
    • Contains enzymes for chemical reactions
  6. Endoplasmic Reticulum
    • Rough: Process protein for secretion and synthesize phospholipids
    • Smooth: Synthesize fats and steroid
  7. Golgi Complex
    Modify and secrete protein from ER and synthesize cell membrane
  8. Lysosome
    Hydrolitic enzyme that digests and recycles cell structures
  9. Mitochondrion
    Contains the structures of the synthesis of ATP from reaction
  10. Nucleus
    Contain genetic information for replication of DNA and synthesize protein
  11. Ribosome
    Site of protein synthesis using mRNA templates
  12. ATP
    Energy form stored in cells obtained from oxidation of food
  13. Muscle Fibers
    • Contain actin and myosin protein fibers
    • Contract when nurse impulse increases CA++
    • Get energy from ATP
  14. Stage 1: Digestion of Carbohydrates
    • Salivary Amylase breaks down CHO into smaller disaccharides
    • Pancreatic amylase in small intestine hydrolyze CHO¬†
    • Hydrolyzes maltose, lactose and sucrose to monosaccharides
  15. Stage 2: Glycolysis
    • Metabolic pathway that uses glucose
    • Degrades 6 C molecule to 3 C pyruvate molecules
    • anaerobic
  16. Glycolysis
    • 1. Phospholyration
    • 2. Isomerization
    • 3. Second phospholyration
    • 4. Cleavage
    • 5. Seond isomerization
    • 6. Produce first energy rich compound
    • 7. First ATP is produces
    • 8. Formation 2-Phosphogycerate
    • 9. Produce second energy rich compound
    • 10. Second ATP is produced
