Hace 1 día · The most prominent roles of mitochondria are to produce the energy currency of the cell, ATP (i.e., phosphorylation of ADP), through respiration and to regulate cellular metabolism. The central set of reactions involved in ATP production are collectively known as the citric acid cycle , or the Krebs cycle, and oxidative phosphorylation .
Hace 21 horas · Metabolic reactions may be categorized as catabolic—the breaking down of compounds (for example, of glucose to pyruvate by cellular respiration); or anabolic—the building up of compounds (such as proteins, carbohydrates, lipids, and nucleic acids).
The respiratory system provides oxygen to the body's cells while removing carbon dioxide, a waste product that can be lethal if allowed to accumulate. There are 3 major parts of the respiratory system: the airway, the lungs, and the muscles of respiration.
Hace 1 día · How Does Respiratory System Work? The respiratory system does its job when the lungs take in oxygen and get rid of the carbon dioxide while we breathe. The entire process is carried out automatically and begins with the lungs filling up with air, which contains oxygen and other elements.
Hace 5 días · There are three main stages of cellular respiration: glycolysis, Krebs cycle and oxidative phosphorylation (electron flow). Glycolysis occurs in the cytoplasm of the cell, this is where one glucose molecule (C 6 H 12 O 6 ) is converted to two molecules of pyruvate, and also the production of 2 ATP.
Hace 3 días · External respiration is the process of exchanging oxygen and carbon dioxide between the air inside the alveoli and the blood in the capillaries of the lungs. Air inside the alveoli contains a higher partial pressure of oxygen compared to the blood in the capillaries.
Hace 21 horas · Compare and contrast aerobic and anaerobic respiration. Click the card to flip 👆. both processes include glycolysis, the citric acid cycle, and oxidative phosphorylation. In aerobic, the final electron acceptor is oxygen and in anaerobic the final electron acceptor is a different substance.
