These reactions take place in the matrix of the mitochondria of eukaryotic cells. In prokaryotic cells, it takes place in the cytoplasm. The overall reaction is as follows:
What is the link reaction between glycolysis and the citric acid cycle?
Oxidative decarboxylation, sometimes referred to as the link reaction or the transition reaction, is the link between glycolysis and the citric acid cycle. Pyruvate is transfered into the mitochondrial matrix via a protein known as pyruvate translocase.
How does NADH work in cellular respiration?
This is important, as later in the process of cellular respiration, NADH will power the formation of much more ATP through the mitochondria ’s electron transport chain. In the next stage, pyruvate is processed to turn it into fuel for the citric acid cycle, using the process of oxidative decarboxylation.
Where does glycolysis occur?
Glycolysis. Glycolysis is the first stage of aerobic respiration and occurs in the cytoplasm of the cell. It involves the splitting of 1 six-carbon sugar molecule into 2 three-carbon pyruvate molecules. This process creates two ATP molecules.

Where does aerobic respiration occur?
Anaerobic respiration in humans occurs primarily in muscle cells during high-intensity exercise. This might occur if you're pushing your limits during an aerobic activity, like spinning or a cardio workout, and the oxygen supply to your muscles is insufficient to maintain aerobic-only respiration. Anaerobic respiration also occurs with activities that require short, intense bursts of muscle power, such as sprinting or power lifting.

Does aerobic respiration generate more ATP?
ATP stores the energy needed to power cellular functions. With aerobic respiration, the pyruvate generated from glycolysis goes through an additional series of biochemical reactions to generate more ATP. This does not occur with anaerobic respiration. Advertisement.
What is the cause of anaerobic respiration?
Anaerobic respiration in humans occurs in muscles during strenuous exercise when sufficient oxygen is not available. It results in the build-up of lactic acid leading to muscle fatigue. When there is an inadequate supply of oxygen during intense exercise, muscles derive energy from anaerobic respiration. Less energy is produced in anaerobic ...
Why is anaerobic respiration less energy?
Less energy is produced in anaerobic respiration due to the partial breakdown of glucose. Pyruvic acid, which is the product of glycolysis is converted into lactic acid by lactate dehydrogenase.
