Which is correct about CO2 released in cellular respiration? -CO2 is released when glucose is converted to pyruvate in the mitochondrial matrix.

During cellular respiration the cell uses oxygen to break down sugar. Breaking down sugar produces the energy your body needs. Carbon dioxide is the waste product of cellular respiration that you breathe out each time you breathe. Blood picks up oxygen and releases carbon dioxide in the lungs.

While photosynthesis requires carbon dioxide and releases oxygen, cellular respiration requires oxygen and releases carbon dioxide. It is the released oxygen that is used by us and most other organisms for cellular respiration.

Question: Which Is Correct About CO2 Released In Cellular Respiration? CO2 Is Released When Glucose Is Converted To Pyruvate In The Mitochondrial Matrix. Co2 Is Formed When Oxygen Accepts Electrons From The Mitochondrial Electron Transport Chain.

And what exactly is the role of oxygen? Oxygen is the final electron acceptor of the electron transport chain in the final step of cellular respiration. Oxygen combines with electrons and hydrogen ions to produce water.

What is the role of oxygen in cellular respiration? Oxygen accepts high-energy electrons after they are stripped from glucose. Cellular respiration accomplishes two major processes: (1) it breaks glucose down into smaller molecules, and (2) it harvests the chemical energy released and stores it in ATP molecules.

Oxygen plays a critical role in respiration, the energy-producing chemistry that drives the metabolisms of most living things. We humans, along with many other creatures, need oxygen in the air we breathe to stay alive. Oxygen is generated during photosynthesis by plants and many types of microbes.

There are three steps of cellular respiration: glycolysis, the citric acid cycle, and oxidative phosphorylation. The main role of glucose in each of these steps is to provide energy in its bonds. In glycolysis, glucose enters the cell.

Oxygen isn’t necessary for the production of all ATP in your cells, because it is only used in the last stage of cellular respiration.

Most of the ATP in cells is produced by the enzyme ATP synthase, which converts ADP and phosphate to ATP. ATP synthase is located in the membrane of cellular structures called mitochondria; in plant cells, the enzyme also is found in chloroplasts.

When Oxygen is not available, the cell is forced to produce energy (=ATP) through ANAEROBIC processes, that produce much less energy (about 15 times less), than AEROBIC processes. Oxygen is essential for the functioning of the electron transport chain.

Oxygen plays a vital role in energy production via a system called electron transport chain (ETC), which is an important component of cellular respiration. Oxygen acts as a final electron acceptor that helps move electrons down a chain that results in adenosine triphosphate production.

During the process of photosynthesis, cells use carbon dioxide and energy from the Sun to make sugar molecules and oxygen. These sugar molecules are the basis for more complex molecules made by the photosynthetic cell, such as glucose.

Glucose is broken does to carbon dioxide and water, and the cell captures some of the released energy to make ATP. photosynthesis produces glucose and oxygen, which is then used in cellular respiration to produce water and carbon dioxide, which is then used by photosynthesis.

Decomposers, such as bacteria and fungi, derive their nutrients by feeding on the remains of plants and animals. The bacteria and fungi use cellular respiration to extract the energy contained in the chemical bonds of the decomposing organic matter, and so release carbon dioxide into the atmosphere.

Photosynthesis converts carbon dioxide and water into oxygen and glucose. Cellular respiration converts oxygen and glucose into water and carbon dioxide. Water and carbon dioxide are by- products and ATP is energy that is transformed from the process.

anaerobic respiration

Anaerobic respiration

“Respiration is defined as a metabolic process wherein, the living cells of an organism obtains energy (in the form of ATP) by taking in oxygen and liberating carbon dioxide from the oxidation of complex organic substances.”

Aerobic (“oxygen-using”) respiration occurs in three stages: glycolysis, the Krebs cycle, and electron transport.

The main purpose of respiration is to provide oxygen to the cells at a rate adequate to satisfy their metabolic needs. This involves transport of oxygen from the lung to the tissues by means of the circulation of blood.

Respiration

• Working your muscles.
• Growth and repair of cells.
• Building larger molecules from smaller ones i.e. proteins from amino acids.
• Allowing chemical reactions to take place.
• Absorbing molecules in active transport.
• Keeping your body temperature constant.
• Sending messages along nerves.

The process of respiration also releases energy in the form of heat. The heat is used to maintain the relatively high body temperature of mammals and birds. Respiration involves chemical reactions that break down nutrient molecules in living cells to release energy. Aerobic respiration needs oxygen.

Answer

• produces energy for maintenance and repair of cells and tissues;
• produces energy for muscular activities and movement;
• prodices energy for nerve impulse conduction in animals and people;
• produces energy for light bioluminescent organisms.
