There are three main stages of aerobic respiration – glycolysis, the Krebs Cycle, and the electron transport chain – each of which deserves an entire article all to itself, but when looking at the overall process of cellular respiration, we will only look at these stages at a somewhat basic level, leaving out the specific details of every chemical reaction in each stage. Glycolysis occurs in the cytoplasm and produces pyruvates; these pyruvates enter the mitochondria and aid in TCA cycle. Substrate level phosphorylation - The glycose has two phosphate groups added to it from two ATP molecules. These intermediaries are critical in the aerobic respiration that occurs in the next phase of glucose breakdown. This produces acetyl CoA, which in turn helps produce citric acid. The Stages of Respiration: Glycolysis– occurs in the cytoplasm which can take place in aerobic or anaerobic conditions. a) oxidative phosphorylation b) pyruvate oxidation c) glycolysis d) Krebs cycle In this step of aerobic respiration, the ATP is ready to release the energy stored in the molecular bonds of pyruvates. In this/these process(es), carbon dioxide is produced, This stage of aerobic respiration occurs in the cytoplasm. In this process the cell gains a net of 2 ATP molecules. The first stages of respiration occur in the cytoplasm of cells, but most of the energy released is in the mitochondria .

In this stage of aerobic respiration, remaining energy from the glucose will be released by the electron transport chain. This energy is used to power several reactions in the cell. Glycolysis (sugar splitting) involves three key stages: 1. Glycolysis is the first stage and as it does not require oxygen and occurs in the cytoplasm it is in both anaerobic and aerobic respiration. Aerobic Respiration. (A number may be used more than once.) It can be found in the cytoplasm and the mitochondria. In cellular respiration, carbohydrates and other metabolites are oxidized, and the resulting energy-transfer reactions support the synthesis of ATP. out of the mitochondria and into the cytoplasm. out of the cell. 2 NADH produced What happens to a cell after glycolysis? During glycolysis, molecules of glucose are broken down to yield four molecules of ATP, two three-carbon molecules called pyruvate and two molecules of nicotinamide adenine dinucleotide, or NADH. Eventually, in this stage the electrons along with the protons will be added to oxygen. When a cell needs to release energy, the cytoplasm (a substance between a cell's nucleus and its membrane) and mitochondria (organelles in cytoplasm that help with metabolic processes) initiate chemical exchanges that launch the breakdown of glucose. That's exactly what happens in this stage. Glycolysis, the first stage of respiration, occurs in the cytoplasm.A molecule of glucose splits into two molecules of pyruvate. Buy Find arrow_forward. A.
