Aerobic respiration is a cellular process that converts glucose into ATP in the presence of oxygen, involving stages such as glycolysis, the link reaction, the Krebs cycle, and oxidative phosphorylation. It takes place within the mitochondria, except for glycolysis, which occurs in the cytoplasm. This process is crucial for energy production in aerobic organisms, contrasting with less efficient anaerobic respiration.

Glycolysis is the first step in aerobic respiration, where glucose is broken down into pyruvate, producing ATP and NADH
The link reaction connects glycolysis to the Krebs cycle by converting pyruvate into acetyl CoA, releasing carbon dioxide and generating NADH
The Krebs cycle is a series of reactions that occur in the mitochondria, breaking down acetyl CoA to produce ATP, NADH, and FADH2
The electron transport chain is a series of protein complexes on the inner mitochondrial membrane that transfer electrons from NADH and FADH2, creating a proton gradient
ATP synthase uses the proton gradient to produce ATP from ADP and inorganic phosphate
Oxygen is the final electron acceptor in oxidative phosphorylation, combining with electrons and protons to form water
Mitochondria have a double membrane system, with the inner membrane folded into cristae, and contain the matrix, intermembrane space, and outer membrane
Mitochondria are the site of aerobic respiration, producing ATP through the Krebs cycle and oxidative phosphorylation
Aerobic respiration is more efficient, producing up to 36 ATP per glucose molecule, while anaerobic respiration produces less ATP
Aerobic respiration produces carbon dioxide and water as byproducts, while anaerobic respiration produces lactic acid, ethanol, or carbon dioxide
Aerobic respiration occurs in the mitochondria of eukaryotic cells and is essential for energy production, while anaerobic respiration occurs in the cytoplasm and is crucial in low oxygen environments or during high-intensity exercise

The process of aerobic respiration includes four stages: ______, the link reaction, the Krebs cycle, and oxidative phosphorylation.
glycolysis
01
Glycolysis oxygen requirement
Glycolysis is anaerobic, does not require oxygen.
02
Net ATP gain in glycolysis
Glycolysis yields a net gain of two ATP molecules.
