Anatomy of the Heart. Your heart is located under your ribcage in the center of your chest between your right and left lungs. Its muscular walls beat, or contract, pumping blood to all parts of your body. The size of your heart can vary depending on your age, size, and the condition of your heart.
In anaerobic respiration, NADH loses its electrons to other molecules in the process of fermentation for the purpose of regenerating the NAD+ needed to continue oxidizing organic molecules to produce ATP by substrate-level phosphorylation.
Stage 2 Aerobic Respiration. During aerobic cellular respiration, the pyruvate produced during glycolysis enters a mitochondrion where it is converted to a two-carbon compound, making a reaction. A Carbon dioxide molecule, a NADH molecule, and a two-carbon acetyl group are produced because of this reaction.n anaerobic process is a process that uses metabolism without air, while an aerobic process is a process that uses metabolism with air. Synopsis of Cellular Respiration. In Cellular Respiration, energy in organic compounds, including glucose, is harnessed.
