This is the starting molecule for cellular respiration and an important source of energy in cells.
In a chemical reaction, only the atoms present in the reactants can end up in the products. No new atoms are created, and no atoms are destroyed. In a chemical reaction, reactants contact each other, bonds between atoms in the reactants are broken, and atoms rearrange and form new bonds to make the products.
Question 2
Answer- response
Blood Provides the Body's<span> Cells with Oxygen and Removes Carbon Dioxide. Blood absorbs oxygen from air in the lungs. It </span>transports<span> the oxygen to cells </span>throughout the body<span>, and it removes waste carbon dioxide from the cells</span>
Both aerobic and anaerobic respiration involve chemical reactions which take place in the cell to produce energy, which is needed for active processes. Aerobic respiration takes place in the mitochondria and requires oxygen and glucose, and produces carbon dioxide, water, and energy.
