How are respiration and fermutation similar?
Respiration and fermentation are similar in that both processes are ways for cells to generate energy from glucose. They both begin with glycolysis, which breaks down glucose into pyruvate, producing a small amount of ATP. While respiration requires oxygen and leads to the complete oxidation of glucose, fermentation occurs in the absence of oxygen and results in the partial breakdown of glucose, yielding byproducts like lactic acid or ethanol. Despite their differences in efficiency and end products, both processes ultimately serve to supply energy to cells.
