Choose all of the following true statements. Hint: 6 statements are true. □ If an electron moves from an atom of higher electronegativity to an atom with lower electronegativity, energy is released. O Glycolysis occurs with or without oxygen present. Other biomolecules such as lipids, disaccharides, and proteins can enter the biochemical pathway of aerobic respiration just not directly into the first step of glycolysis. Molecules other than glucose can be broken down and used to build up ATP in aerobic respiration. Glycolysis occurs during both alcohol and lactic acid fermentation, producing 2 net ATP. The higher the electronegativity of an atom, the tighter it holds an electron and the lower its potential energy. Water is the final electron acceptor of the ETC in aerobic respiration. Each protein component of the ETC in aerobic respiration is more electronegative than the last.
