Natasha's Model of Cellular Respiration

Explanation:

Cellular respiration is the process of energy production that occurs in mitochondria. This process requires an energetic substrate, such as glucose.

Glycolysis: Glucose is converted to pyruvate by the process of glycolysis, which occurs in the cytoplasm.

Krebs Cycle: The pyruvate is then transformed into acetyl-CoA. In the presence of oxygen, energy production in the mitochondria depends on the Krebs cycle. The Krebs cycle starts with successive transformations from Acetyl-CoA to acetate and then to Citrate, through oxidation processes.

Electron Transport Chain: These oxidative processes in the Krebs cycle are necessary for electron transfer to occur. The electron transport chain is a series of protein complexes and molecules in the inner mitochondrial membrane that transfer electrons and generate ATP.

Therefore, Natasha's model of cellular respiration shows the aerobic pathway consisting of glycolysis, the Krebs cycle, and the electron transport chain when there is enough oxygen available for the process.
