Respiration
It’s not breathing!

“RESPIRATION”
1. Organism respiration
The exchange of gases
(Oxygen and carbon
dioxide)between an
organism and the
environment.
2.
Cellular respiration
The life function
which involves the
transfer of glucose
and oxygen into ATP

Why do we need energy?
Organisms also need energy when they are resting:
- Brain uses ATP to maintain homeostasis
- Transport molecules in and out of the cell
- Keep our heart pumping blood around our body

ATP – ADP Cycle Summary
ADP  ATP
ATP is created during the
process of Cellular Respiration
1 phosphate Added (Di  Tri)
ATP  ADP
Energy is Released for life
functions
1 phosphate Removed
(Tri  Di)
Two kinds of Cellular Respiration
1. Aerobic Respiration
2. Anaerobic Respiration
• Aero- air
• An- not/without
• Aero- air
Definition: making energy
(Respiration) with oxygen
•What type of cells?
Plants and Animals
•Where does it occur?
Mitochondria
Definition: making
energy (Respiration)
without oxygen
•What type of cells?
Bacteria, Yeast (Fungus)
Fatigued muscle
•Where does it occur?
Cytoplasm
Ingredients for Cellular Respiration
Reactant- a substance that is changed during
a chemical reaction
Product- a substance that is the result of a reaction

Product or reactant?
AEROBIC respiration
• oxygen is used
• most living organisms (plants and animals)
• occurs in mitochondria
Enzymes- proteins that speed up or slow
down chemical reactions.
C6H12O6
O2
Enzymes
Glucose + Oxygen 
CO2 H2O
Carbon + Water + ATP
Dioxide
Makes 36 ATP each time!!!
Electron Transport Chain
(ETC; 3rd Stage)
Kreb’s Cycle
(2nd Stage)
•Breaks down the 3
carbon pyruvic acid into
a 1 carbon CO2
•Releases 2
more ATP
• Releases 32
more ATP
ANAEROBIC respiration = Fermentation
• NO oxygen is used
• bacteria, yeast and fatigued muscles
• Occurs in cytoplasm
LACTIC ACID FERMENTATION
fatigued muscles
