diffrentiate between artries and veins
also diffrentiate between aerobic and anaerobic respiration
Arteries | Veins |
Arteries are thick walled | Veins are thin-walled |
Blood flows under high pressure in the arteries | Bring back blood from the organs to the heart and blood is no longer under pressure. |
Arteries are generally red in colour since they carry pure, oxygenated blood | Veins are generally blue in colour since they carry impure, deoxygenated blood. |
| Aerobic respiration | Anaerobic respiration |
It occurs in the presence of O2. It occurs in the cytoplasm and mitochondria. It always releases CO2 and H2O as end product. It involves production of high energy i.e 36 ATP. C6H12O6 → CO2 + H2O + ATP ( Energy) | It occurs in the absence of O2. It occurs only in the cytoplasm. End products are mostly lactic acid and alcohol It involves production of less energy only 2 ATP C6H12O6 → Lactic acid /alcohol + energy |
