Study Notes

Respiratory System

Deals with gases or exchange of gases
Two main gases involved: Oxygen (O2) - needed, Carbon Dioxide (CO2) - waste

Gas Exchange Process

Environment (O2) → Lungs → Blood → Cells of the Body → CO2 → Collected by Blood → Lungs → Environment (CO2)

Cellular Respiration

Yields energy in the form of ATP (Adenosine Triphosphate)
Energy production: C6H12O6 + O2 = ATP, CO2, H2O
Glucose comes from Carbohydrates processed by the Digestive system, specifically from Small Intestine

Cellular Respiration Terms

ATP (Adenosine Triphosphate)
ADP (Adenosine Diphosphate)
NADH (Nicotinamide Adenine Dinucleotide)
FAD (Flavin Adenine Dinucleotide)
DHAP (Dihydroxy Acetone Phosphate)
GAP (Glyceraldehyde Triphosphate)
Fructose 1-6 Biphosphate

Aerobic vs Anaerobic

Aerobic: needs oxygen for cellular respiration
Anaerobic: no oxygen needed, uses fermentation

Glycolysis

Step 1: 2 phosphates from 2 ATPs are removed and become ADP
Step 2: phosphates attach to 6 Carbon atoms of Glucose, converting it to Fructose 1-6 Biphosphate
Step 3: Fructose 1-6 Biphosphate divides into DHAP and GAP
