Why does breathing becomes faster when we do physical exercise ?? Answer it fast guyss plzz !! :):)

The rate of breathing increases during exercise because our body needs more energy during exercise. More energy needs more oxygen, so the rate of breathing increases to get more oxygen into our body.

When we exercise we continually need to form ATP by breaking down glucose. in cellular Respiration, which requires oxygen. While exercising we need more and more ATP, so we need to break down glucose at a faster rate, so we need to form more oxygen eventually making us to breath faster.

Hope this is right!!
