Other biomolecules such as lipids, disaccharides, and proteins can enter the biochemical pathway of aerobic respiration, just not directly into the first step.
Water is the final electron acceptor of the ETC in aerobic respiration.
If an electron moves from an atom of higher electronegativity to an atom with lower electronegativity, energy is released.
Glycolysis occurs during both alcohol and lactic acid fermentation, producing 2 net ATP.
Each protein component of the ETC in aerobic respiration is more electronegative than the last.
Glycolysis occurs with or without oxygen present.
Molecules other than glucose can be broken down and used to build up ATP in aerobic respiration.
QUESTION 4
What is the role of O2 in aerobic respiration?
- is required directly by ATP synthase to build up ATP
- allows for glycolysis to occur, helping produce pyruvate
- is directly required for the formation of oxaloacetate during the citric acid cycle
- serves as the most electronegative member of the ETC, picking up electrons and H+ and forming water.
QUESTION 5
Choose all of the following statements which describe the relationship between the structure and function of the mitochondrion.
- The mitochondrion is located inside the nucleus and thus fuels all metabolic processes in the cell.
- The liquid inside the mitochondrion facilitates the movement of H+ across the mitochondrial membrane.
- The mitochondrion is double membrane-bound, providing an intermembrane space where an H+ gradient can build up during oxidative phosphorylation.
- The inner membrane of the mitochondrion is folded into cristae, providing increased surface area allowing for more ETC's to be embedded.
