Human activites have greatly increased carbon dioxide levels in the atmosphere and nitrogen levels in the biosphere. Altered Altered biogeochemical cycle combined with climate change increase the vulnerability of biodiversity, food security, human health, and water quality to a changing climate.
<span>In the skeletal muscle cells of vertebrates, as many as 38 molecules of ATP are produced from one molecule of glucose. This is less than might be expected, because electrons from NADH produced during glycolysis must be shuttled through the inner mitochondrial membrane at a cost.
</span>The energy of the electrons can be used to make ATP and in eukaryotes, glycolysis occurs in the <span>cytosol, outside mitochondria. </span>
Carbon dioxide is what humans exhale, giving trees carbon dioxide will produce oxygen
