Oxygen enters the body through the respiratory system when we inhale, traveling down the trachea and into the lungs. In the alveoli (tiny air sacs), oxygen diffuses into the bloodstream, binding to hemoglobin in red blood cells. The oxygen-rich blood is then pumped by the heart through the arteries and capillaries, ultimately reaching internal cells where oxygen diffuses out of the blood and into the cells for cellular respiration. This process is vital for producing energy in the form of ATP.
This type of respiration is called internal respiration. In internal respiration, oxygen diffuses from the bloodstream into the cells of tissues, while carbon dioxide diffuses from the cells into the bloodstream.
The anaerobic pathway occurs in the cytoplasm of cells. It is a metabolic process that does not require oxygen and is used to produce energy, typically in situations where oxygen is scarce or during intense exercise.
Yes, the non-oxidative glycolytic pathway is considered part of anaerobic metabolism. This pathway allows cells to generate ATP without the need for oxygen, primarily through the conversion of glucose to lactate or ethanol, depending on the organism. It is especially important in conditions where oxygen is scarce, such as in muscle cells during intense exercise. Overall, it facilitates energy production when oxidative phosphorylation is not feasible.
The exchange of oxygen and carbon dioxide between internal leaf cells and the external environment is crucial for photosynthesis and respiration. During photosynthesis, cells take in carbon dioxide and release oxygen, while during respiration, cells take in oxygen and release carbon dioxide. This exchange allows plants to produce energy and oxygen while removing carbon dioxide from the air.
When animal cells enter the anaerobic pathway of glycolysis, they convert pyruvate into lactic acid (lactate) as a byproduct. This process occurs when oxygen is scarce, allowing for the regeneration of NAD+ needed to continue glycolysis. The accumulation of lactic acid can lead to muscle fatigue, but it allows for continued ATP production in low-oxygen conditions.
Oxygen is transported first by air down the trachea and then transform to the hemoglobin of the blood to the cells. This is the pathway of oxygen in the human system.

Oxygen enters the respiratory system through the nose or mouth and travels down the trachea into the lungs. In the lungs, oxygen diffuses into the tiny air sacs called alveoli and is then transported into the bloodstream by binding to hemoglobin in red blood cells. The oxygen-rich blood is pumped by the heart to the rest of the body, where it is delivered to cells for energy production.
Aerobic and anaerobic. Determined by the availability of oxygen to the cells.
Oxygen enters the body through the respiratory system, where it is inhaled and travels down the trachea into the lungs. In the lungs, oxygen diffuses into the bloodstream through the alveoli. The oxygen-rich blood is then pumped by the heart to various parts of the body through arteries, eventually reaching individual cells where it is used in cellular respiration to produce energy.
The pathway of oxygen is like a tube or pipe in the breathing system.

no, it is anaerobic metabolism. (without oxygen, rather than with oxygen.)
