CO2 release in the human body takes place during the Krebs Cycle stage of respiration. The Krebs cycle is an absolutely crucial phase as it give us energy.

It depends on the surface of the levels. the rougher the surface, the greater is the frictional force. for rougher surfaces, you would need to exert greater force to move the object. the concept is that, you must overcome the frictional force in order to bring the object into motion. this is the reason why we add lubricants to the joints so they could easily move. this answer was on
