Cellular Respiration

• Chapter 6 (2nd half)
• Biology book pages 123 - 131

• Define the following
• Aerobic with oxygen
• -aerobe an organism that uses oxygen
• Anaerobic with out oxygen
• -anaerobe an organism that doesnt use oxygen
• There are 3 stages of Aerobic Respiration
• 1. Glycolysis - yielding 2 ATP
• 2. Krebs Cycle or Citric Acid Cycle - yielding
  2 ATP
• 3. Electron Transport Chain (ETC) - yielding 32
  ATP

Cellular (aerobic) Respiration

• 
  mitochondrion
• C6H1206 6O2 -------? 6CO2 6H2O 36ATP
• enzymes
• Even though monosaccharides contain much energy,
  our cells cant directly use this energy. Our
  cells must convert monosaccharide energy into ATP
  (the kind of energy our cells know how to use).
  This happens in our powerhouses (mitochondria)
  and the process is called aerobic respiration.

Glycolysis Main idea glucose is split into 2
pyruvates releasing E Question What is the net
gain of ATP during glycolysis?
7
Krebs Cycle Overview

• Aerobic
• Occurs in the matrix (inner compartment)
• Products (per glucose)
• 2 ATP
• 6 CO2
• 8 NADH
• 2 FADH2.
• These energy carriers now enter the electron
  transport chain (ETC).

Electron Transport Chain

• Aerobic
• Ocurs in the inner membrane (cristae shelves)
• Main idea the E stored in FADH2 and NADH is
  transferred to
• 32 ATP
• Products
• 32 ATP
• 10 NAD
• 2 FAD
• 6 H20

Breakdown of One Glucose Molecule

• Glycolysis Produces
• 2 ATP 2 Pyruvate 2 NADH
• Krebs Cycle (including pre-Krebs) - Produces
• 2 ATP 6 CO2 8 NADH 2FADH2
• ETC - Produces
• 32 ATP 6 H2O
