During cellular respiration, a glucose molecule is gradually broken down into carbon dioxide and water . Along the way, some ATP is produced directly in the reactions that transform glucose. Much more ATP, however, is produced later in a process called oxidative phosphorylation.
How is glucose broken down and what is it broken down into?
The six carbon sugar, glucose, is cut in half and converted into two three-carbon sugars called pyruvate . ... If oxygen is present, then glucose can be broken all the way down into carbon dioxide and water. This process is called aerobic respiration because it requires air (oxygen).
What does glucose do in cellular respiration?
Cellular respiration releases stored energy in glucose molecules and converts it into a form of energy that can be used by cells.
Is glucose destroyed in cellular respiration?
During cellular respiration, glucose is broken down in the presence of oxygen to produce carbon dioxide and water. Energy released during the reaction is captured by the energy-carrying molecule ATP (adenosine triphosphate).
What type of respiration breaks down glucose?
Aerobic respiration breaks down glucose and combines the broken down products with oxygen, making water and carbon dioxide. The carbon dioxide is a waste product of aerobic respiration because cells do not need it.
What is the connection between glucose oxygen and cellular respiration?
During aerobic cellular respiration, glucose reacts with oxygen, forming ATP that can be used by the cell. Carbon dioxide and water are created as byproducts. In cellular respiration, glucose and oxygen react to form ATP.
How does a cell use glucose?
Cells convert glucose to ATP in a process called cellular respiration . Cellular respiration: process of turning glucose into energy In the form of ATP. Before cellular respiration can begin, glucose must be refined into a form that is usable by the mitochondrion.
Where does cellular respiration occur?
Cellular respiration is the process that occurs in the mitochondria of organisms (animals and plants) to break down sugar in the presence of oxygen to release energy in the form of ATP. This process releases carbon dioxide and water as waste products. 8. Plants have mitochondria and can perform cellular respiration.
What is the main product of cellular respiration?
Cellular respiration, the process by which organisms combine oxygen with foodstuff molecules, diverting the chemical energy in these substances into life-sustaining activities and discarding, as waste products, carbon dioxide and water.
How do humans use cellular respiration?
Cellular respiration in humans starts in the digestive and respiratory systems. ... The cells use the glucose and oxygen from the circulatory system for energy production . They deliver the waste product, carbon dioxide, back to the red blood cells and the carbon dioxide is released to the atmosphere through the lungs.
What are the 3 main parts of cellular respiration?
Cellular respiration is made up of three sub-processes: glycolysis, the Citric Acid Cycle (Krebs Cycle), and the Electron Transport Chain (ETC) . Let’s talk about each one in detail.
What is the correct order of cellular respiration?
The stages of cellular respiration include glycolysis, pyruvate oxidation, the citric acid or Krebs cycle, and oxidative phosphorylation .
What are the three pathways of breakdown of glucose?
Cellular respiration is a collection of three unique metabolic pathways: glycolysis, the citric acid cycle, and the electron transport chain . Glycolysis is an anaerobic process, while the other two pathways are aerobic.
What type of cellular respiration requires oxygen?
Aerobic respiration is a specific type of cellular respiration, in which oxygen (O 2 ) is required to create ATP.
In which two locations does cellular respiration occur?
Cellular respiration takes place in both the cytosol and mitochondria of cells. Glycolysis takes place in the cytosol, whereas pyruvate oxidation, the Krebs cycle, and oxidative phosphorylation occur in the mitochondrion. Figure 1 shows the locations of the main biochemical reactions involved in cellular respiration.
What is the role of glucose in cellular respiration quizlet?
What is the role of glucose in cellular respiration? glucose is oxidized and thus releases energy .
