Glycolysis and Krebs Cycle in the Cell

This animation traces cellular respiration through its real cellular locations, showing glycolysis splitting glucose into pyruvate in the cytoplasm, then pyruvate entering the mitochondrial matrix for the Krebs cycle. Organelle structures like the double membrane, cristae, and matrix are highlighted alongside each reaction step, with NADH, FADH2, and ATP/GTP production tracked. Useful for second-year biology students connecting biochemical pathways to subcellular architecture and building intuition for where each stage of respiration physically occurs.
