Respiration and gas exchange - Coggle Diagram
Respiration and gas exchange
Difference with ventilation
Ventilation: movement of air in and out of the guns
Respiration: a chemical process involving cells
Why do we need respiration?
Contraction of muscles
Linking amino acids
Cell division
Active transport
Transmitting nerve impulses
Producing heat
Energy from the brokerage of glucose
Final equation: C6 H12 O6 + 6 O2 = 6 CO2 + 6 H2O+ 38 ATP
Anareobic respiration
First step in the whole process: glycolysis
C6 H12 O6 = 2 C3 + 2 ATP
Glucose = pyruvate + ATP
Without the presence of oxygen, it continues
Second step: Fermentation
Yeast
Ethanol Fermentation
2 C3= 2 C2 H5 OH + 2 CO2
Pyruvate= 2 alcohol molecules + 2 carbon dioxide molecles
Animals
Lactic acid Fermentation
2 C3= Lactic acid
With the presence of oxygen
Aerobic respiration
Pyruvate turns into Acetyl CoA+ CO2
Second step: Kreb's cycle
2 Acetyl CoA= ATP + molecules to generate a H+ gradient
Step 3: Electron transport chain
The molecules produced in the Kreb's cycle+ 6 O2 = 6 H2O+ 32 or 34 ATP
