Answer:
Proteins are responsible for the <u>mass </u>and <u>fat </u>of much of our bodies (and other organisms). The instructions for making protein are encoded in <u>DNA</u>. These genes provide the sequence of building blocks known as <u>nucleotides</u>. This string of amino acids then folds into different shapes. The structure of proteins determines what a <u>molecule </u>can do. Proteins contain carbon, hydrogen, oxygen, and nitrogen.

Answer:
This is because in biology, energy is transferred from organism to organism and some energy is lost along the way. Each energy transfer results in a loss of energy, so that energy is always at a lower level and can never be returned to its original high energy level. On the other hand, chemical elements can form products, then that reaction can be reversed and break back down into reactants. Additionally, the law of conservation of matter says that matter can't be created or destroyed, only transferred from one form to another.
The end products are also different, in every living organism water and carbon dioxide are produced in aerobic respiration, whereas in anaerobic respiration, animals produce lactic acid, while plants and micro-organisms produce ethanol.
