Transcript and Presenter's Notes

Title: Cell metabolism


1
Cell metabolism
2
Breakdown of glucose
  • Without oxygen anaerobic catabolism
  • Location cytoplasm
  • Into lactic acid
  • Process called glycolysis
  • Produces little ATP

GLUCOSE
3
  • With oxygen aerobic catabolism
  • Location cytoplasm mitochondria
  • Forms CO2, H2O, and lots of ATP
  • Uses enzymes
  • Steps glycolysis, Krebs, Electron transport chain

4
No glucose?
  • Breakdown protein and reconstruct into glucose
    regulates blood glucose levels

5
Metabolism of lipids
  • Anabolic
  • excess calories (energy) deposited in adipose
    tissue
  • Catabolic
  • Enters Krebs cycle
  • Release more ATP than carbsWHY?

6
ENZYMES
7
  • Catalysts in living things
  • Reduce required energy for metabolism
  • substrate enzyme --------gt enzyme substrate
    complex -----------gt enzyme products.
  • Induced fit at active site/lock key
  • Examples
  • Digestive break down protein, carbs, fats
    (sucrase, lactase, amylase)
  • Metabolic Polymerases (DNA/RNA synthesis),
    Thrombin (blood clotting)

8
REVIEW
  • CATABOLISM? ANABOLISM?
  • HOW IS THE SIZE OF A COMPOUND RELATED TO ITS
    POTENTIAL ENERGY
  • WHAT TYPE OF COMPOUND CONTAINS THE MOST ENERGY?
  • WHAT 2 TYPES OF COMPOUNDS ARE THE IDEAL ENERGY
    SOURCE OF THE BODY?

9
  • WHAT IS THE END RESULT OF ANAEROBIC RESPIRATION?
  • DOES ANAEROBIC OR AEROBIC RESPIRATION PRODUCE
    MORE ATP?
  • WHAT STEPS OF CELL RESPIRATION DO LIPIDS GO
    THROUGH?

10
  • WHERE IN THE CELL DOES ANAERBIC CELL RESPIRATION
    OCCUR?
  • WHERE IN THE CELL DOES AEROBIC RESPIRATION OCCUR?
  • WHAT ARE THE NAMES OF THE STEPS OF AEROBIC?
  • WHAT ARE THE NAMES OF THE STEPS OF ANAEROBIC?
