The Krebs cycle takes place inside the mitochondria. The Krebs cycle produces the CO2 that you breath out. This stage produces most of the energy ( 34 ATP molecules, compared to only 2 ATP for glycolysis and 2 ATP for Krebs cycle). The electron transport chain takes place in the mitochondria.

Glycolysis takes place in the cytoplasm. Within the mitochondrion, the citric acid cycle occurs in the mitochondrial matrix, and oxidative metabolism occurs at the internal folded mitochondrial membranes (cristae).

In general, cellular respiration can be divided into four stages: Glycolysis, which does not require oxygen and occurs in the mitochondria of all cells, and the three stages of aerobic respiration, all of which occur in mitochondria: the bridge (or transition) reaction, the Krebs cycle and the electron transport chain …

9. Does glycolysis occur inside or outside the mitochondria? Glycolysis happens in the cytoplasm of cells and does not require the presence of oxygen. It is said to be anaerobic.

3 irreversible steps in glycolysis: hexokinase; phosphofructokinase; pyruvate kinase. New enzymes are needed to catalyze new reactions in the opposite direction for gluconeogenesis.

Glucose is the source of almost all energy used by cells. Overall, glycolysis produces two pyruvate molecules, a net gain of two ATP molecules, and two NADH molecules.

decomposition reaction

Vinegar is an aqueous solution of acetic acid and trace compounds that may include flavorings. Vinegar typically contains 5–8% acetic acid by volume. Usually, the acetic acid is produced by the fermentation of ethanol or sugars by acetic acid bacteria.

Vinegar is typically no less than 4% acetic acid by mass.
