Cell Metabolism, Bioenergetics, and Energy Balance

Cell metabolism involves the degradation, synthesis, storage, interconversion, and excretion of nutrients in the body.
Blood contains nutrients and waste products that can be measured to diagnose metabolic diseases.
Changes in blood substances occur during physiological and pathological situations such as fasting, exercise, diabetes, and malnutrition.
Cell nutrients come from the diet, synthesis, and release from storage in the body tissues, and undergo various chemical transformations including degradation, synthesis, storage, interconversion, and excretion.
Cell metabolism provides energy, building blocks, organic precursor molecules, and biosynthetic reducing power for cell growth, maintenance, repair, and division.
Cell metabolism consists of catabolic and anabolic pathways that are oxidative and reductive, respectively.
Cells release energy from fuel molecules by oxidation reactions, which involve REDOX reactions and the addition or removal of oxygen, H atoms, or electrons.
Carrier molecules such as NAD+, NADP+, and FAD act as carriers of reducing power and cycle between oxidative and reductive processes to maintain cell function.
