Oxidative phosphorylation is necessary for most metabolic function. It is highly efficient and the primary means by which ATP is produced, which provides the energy for metabolism.
Mitochondria are often referred to as the "powerhouses" of the cell because their primary function is to produce adenosine triphosphate (ATP), the energy currency of the cell, through the process of oxidative phosphorylation. They also play crucial roles in regulating cellular metabolism, calcium homeostasis, and apoptosis (programmed cell death). Additionally, mitochondria are involved in the production of reactive oxygen species and the metabolism of certain biomolecules.
Phosphorylation primarily occurs in two forms: substrate-level phosphorylation and oxidative phosphorylation. Substrate-level phosphorylation occurs in the cytoplasm during glycolysis and in the mitochondria during the citric acid cycle, where ATP is produced directly from a substrate. Oxidative phosphorylation takes place in the inner mitochondrial membrane, involving the electron transport chain and chemiosmosis, where ATP is generated indirectly through the flow of protons across the membrane. Additionally, there is protein phosphorylation, which is a regulatory mechanism occurring in various cellular locations, including the cytoplasm and nucleus, where proteins are modified by the addition of phosphate groups, often impacting their activity and function.
The sum of physical and chemical processes inside the cell that sustain health and life and produce energy is known as cellular metabolism. Cellular metabolism involves various biochemical reactions that generate energy (such as ATP) and essential molecules needed for cell function, growth, and repair. It includes processes like glycolysis, the citric acid cycle, and oxidative phosphorylation.
Mitochondria are often referred to as the "powerhouses" of the cell because they produce adenosine triphosphate (ATP), the primary energy currency of the cell, through a process called oxidative phosphorylation. They also play crucial roles in regulating cellular metabolism, calcium homeostasis, and programmed cell death (apoptosis). Additionally, mitochondria are involved in the production of reactive oxygen species and the metabolism of certain biomolecules. Their health and function are essential for overall cellular and bodily energy balance.
To manufacture cellular energy, primarily in the form of adenosine triphosphate (ATP), cells require several key components: glucose or other organic molecules as fuel, oxygen for aerobic respiration, and various enzymes to facilitate metabolic reactions. Additionally, mitochondria play a crucial role in the production of ATP through processes like the Krebs cycle and oxidative phosphorylation. Essential cofactors, such as vitamins and minerals, are also necessary for enzyme function and energy metabolism.
Its main function is oxidative phosphorylation.
Oxygen is essential for cellular respiration, where it helps convert nutrients into energy through a process called oxidative phosphorylation. This energy is necessary for various physiological functions in the body, including metabolism, growth, and repair of tissues.

Additionally, mitochondria are involved in the production of reactive oxygen species and the metabolism of certain biomolecules.
Cells that increase their oxygen consumption and cellular function undergo metabolic adaptations such as increasing mitochondrial biogenesis, enhancing oxidative phosphorylation, and upregulating enzymes involved in aerobic metabolism. These adaptations help the cells meet the increased energy demands required for higher functionality.

How we get the energy from the food we eat, its similar to process of burning a candle or a fire, oxygen is how you get the energy and how you control. For example limiting the oxygen limits the energy, like when you sit on a couch your breathing is slow and relaxed versus when you run you huff and puff gasping for air.
