Cell energy can be extracted primarily from three sources: carbohydrates, fats, and proteins. Carbohydrates are broken down into glucose, which is then utilized in cellular respiration to produce adenosine triphosphate (ATP). Fats are metabolized through beta-oxidation, also leading to ATP production, while proteins can be converted into amino acids that enter various metabolic pathways for energy extraction. Overall, these macromolecules serve as fuel for cellular processes, enabling growth and maintenance.
