The main byproducts of cellular respiration are:

1. Carbon Dioxide (CO₂):

   • Main problem: When too much carbon dioxide builds up, it can make our bodies too acidic.
     This can be harmful to our cells.
   • Solution: Our lungs and the breathing systems of aquatic animals help get rid of carbon dioxide efficiently.

2. Water (H₂O):

   • Main problem: Too much water can cause stress for our cells, affecting how they work.
   • Solution: Our body has ways to keep the right balance of water, which helps prevent problems.

These byproducts show how complicated cellular respiration is. They remind us how important it is to keep a stable environment inside our bodies so everything functions properly.
