This substance is made from glucose through glycolysis, and supplies energy to living cells through the krebs cycle when oxygen is present (aerobic respiration), and alternatively ferments to produce lactate when oxygen is lacking (fermentation).

We are tasked to find the substance that is made from glucose through glycolysis, and supplies energy to living cells through the Krebs cycle when oxygen is present (aerobic respiration), and alternatively ferments to produce lactate when oxygen is lacking (fermentation). Upon checking on the Glycolysis cycle, Kreb’s Cycle and fermentation, one common substance is present and called Pyruvate.
