3. How are glucose and oxygen molecules used in cellular growth and repair?

Answer 1: Amino acids are the building blocks of proteins and protein breakdown provides amino acids that are used for cellular function. The carbon and nitrogen derived from these become the building block for nucleotides, nucleic acids, proteins, cells, and tissues. Excess nitrogen must be excreted, as it is toxic.

Answer 2: Within every cell of an organism, oxygen and glucose release energy in a chemical reaction called cellular respiration. This released energy allows the body to move, grow, and keep warm.

Answer 3: Asked same question twice.
