The first stage of cellular respiration is glycolysis. It takes place in the cytosol of the cytoplasm. <span>The word</span><span> </span><span>glycolysis</span><span> </span><span>means “glucose splitting,” which is exactly what happens in this stage. Enzymes split a molecule of glucose into two molecules of pyruvate (also known as pyruvic acid). This occurs in several steps, as shown in</span><span> </span><span>Figure</span><span> </span><span>below</span><span>.</span><span> </span>
