Final answer:
Oxygen is a key component in power movements/events. It serves as an 'electron magnet' in cellular respiration, facilitating ATP synthesis and NADH regeneration. Oxygen is crucial for energy production in humans and other organisms.
Step-by-step explanation:
Oxygen is a key component in power movements/events. The role of oxygen in cellular respiration is to act as an 'electron magnet' and facilitate the flow of electrons in the electron transport chain, which allows for the synthesis of ATP. Additionally, oxygen is essential for the regeneration of NADH, which is required for glycolysis and the citric acid cycle to continue. In humans, oxygen passes from the lungs to the blood, where it combines with hemoglobin and is transported to tissues for energy production.
