What are the three stages of aerobic cellular respiration Brainly?
Answer: Three major steps of aerobic respiration are: Glycolysis Krebs Cycle and Electron Transport Chain. … Krebs Cycle: private molecules are processed to release the energy which is stored between their molecular bond.
What are the three stages of glycolysis?
The glycolytic pathway can be divided into three stages: (1) glucose is trapped and destabilized (2) two interconvertible three-carbon molecules are generated by cleavage of six-carbon fructose (3) ATP is generated.
What is the first step involved in respiration?
The first step in respiration is to perform breathing which involves inhalation of air to get the oxygen followed by exhalation of carbon dioxide. This step is further carried forward through the diffusion of gases into the blood and out of the blood. The freshly diffused oxygen is then transported to the tissues.
What are the main stages of cellular respiration and where do they take place quizlet?
- 1st- Glycolosis. Splitting sugars in cytoplasm energy investment phase -> 2 ATP molecules combine with glucose molecule.

What is complex 4 in the electron transport chain?
Complex IV of the electron transport chain also known as cytochrome c oxidase is a multiunit structure that functions to transfer electrons form cytochrome c to oxygen and in the process form water and help generate a proton gradient. … CuB associates with heme A-3 to help reduce oxygen into water.
What is the order of the electron transport chain?
The ETC proteins in a general order are complex I complex II coenzyme Q complex III cytochrome C and complex IV. Coenzyme Q also known as ubiquinone (CoQ) is made up of quinone and a hydrophobic tail. Its purpose is to function as an electron carrier and transfer electrons to complex III.
What are the electron acceptors in cellular respiration?
Explanation: In cellular respiration oxygen is the final electron acceptor. Oxygen accepts the electrons after they have passed through the electron transport chain and ATPase the enzyme responsible for creating high-energy ATP molecules.
What are the 3 steps of aerobic respiration quizlet?
Aerobic (“oxygen-using”) respiration occurs in three stages: glycolysis the Krebs cycle and electron transport.
What happens during the electron transport chain in cellular respiration?
The electron transport chain is the last stage of the respiration pathway. It is the stage that produces the most ATP molecules. … The electrons transfer their energy to the proteins in the membrane providing the energy for hydrogen ions to be pumped across the inner mitochondrial membrane.
What are the major events of the electron transport chain?
Which stage of cellular respiration produces the most ATP?
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).
What are the steps involved in the process of photosynthesis?
- Absorption of solar energy by the chlorophyll.
- Splitting of water into hydrogen and oxygen by this light energy.
- Conversion of solar energy into chemical energy.
- Reduction of carbon dioxide to form glucose by the transformed chemical energy.
Which of the following stage is not in aerobic respiration?
Fermentation starts with glycolysis but it does not involve the latter two stages of aerobic cellular respiration (the Krebs cycle and oxidative phosphorylation). During glycolysis two NAD+ electron carriers are reduced to two NADH molecules and 2 net ATPs are produced.
What role does cellular respiration play in the water cycle?
What role does cellular respiration play in the water cycle? … It removes H2O from the atmosphere during acetyl CoA formation. It releases H2O to the atmosphere during the citric acid cycle.

What is the first stage of glycolysis?
In the first step of glycolysis the glucose ring is phosphorylated. Phosphorylation is the process of adding a phosphate group to a molecule derived from ATP. As a result at this point in glycolysis 1 molecule of ATP has been consumed.
What is the first step in glycolysis?
Step 1: Glucose is phosphorylated by the enzyme hexokinase to form glucose 6- phosphate. Glucose gains energy by being phosphorylated at the expense of one ATP. Step 2: Glucose 6-phosphate is converted into its isomer fructose 6-phosphate by an isomerase enzyme.
What is the steps of respiration?
Aerobic respiration is divided into three main stages: Glycolysis Citric acid cycle and Electron transport chain.
What are the events or steps in respiration?
It has four stages known as glycolysis Link reaction the Krebs cycle and the electron transport chain. This produces ATP which supplies the energy that cells need to do work. When they don’t get enough oxygen the cells use anaerobic respiration which doesn’t require oxygen.
What is the first step in cellular respiration Class 10?
Which of the following is the correct sequence of electron acceptors in ETS for production of ATP?
