Aerobic respiration uses oxygen to produce ATP. Anaerobic respiration uses inorganic molecules to produce ATP. I hope that answered your question, my friend. :)
Endocytosis is an example of passive form of transportation which is used in the cells to move substances from one point to another. It is described as passive because the process does not require energy.
Active transport is a type of transport used for movement of particles in the cells which require energy for it to occur. The major source of energy for active transport is ATP molecules, which are hydrolyzed to release energy.<span />
