In aerobic respiration of glucose in eukaryotes, two molecules of pyruvic acid is produced in the cytoplasm by glycolysis of one molecule of glucose. The pyruvic acid then enters the mitochondria to go through the Krebs cycle, which will break down the pyruvic acid into carbon dioxide, which is then excreted. Putting a molecule of pyruvic acid through the Krebs cycle yields 1 molecule of ATP (2 ATP per glucose), but importing the pyruvic acid into the mitochondria costs 1 ATP molecule, so the net gain of ATP from the Krebs cycle is +0.
Hydrogen ions and high-energy electrons from glycolysis also need to be imported into the mitochondria to the electron transport chain, which is where the mother-lode of ATP comes from (34 ATP per glucose molecule).
Other molecules such as fatty acids and amino acids typically don't undergo glycolysis, but instead are imported directly into the mitochondria where they enter the Krebs cycle somewhere depending on their molecular structure.
What else can I help you with?
Where is anaerobic respiration take place?
The reactions of anaerobic respiration take place in the cytoplasm.
Where in the cell is pyruvate broken down?
Pyruvate is broken down in the mitochondria of the cell through a process called aerobic respiration. Pyruvate is converted into acetyl-CoA, which then enters the citric acid cycle to produce ATP, the cell's main energy source.
Does cellular respiration begin when the glucose starts breaking down?
Yes, cellular respiration begins with the breakdown of glucose in the cytoplasm of the cell during glycolysis. This process produces energy in the form of ATP and pyruvate, which then enters the mitochondria for further processing in the citric acid cycle and oxidative phosphorylation.
What stages of cellular respiration occur in mitochondria?
The Krebs cycle and electron transport chain stages of cellular respiration occur in the mitochondria. These stages are responsible for generating the majority of ATP that the cell needs for energy. The mitochondria is often referred to as the powerhouse of the cell because of its role in cellular respiration.
How do organisms get glucose in cellular respiration?
We get our glucose from plants or other animals that have eaten plants. And cellular respiration produces the reactants for photosynthesis which produces glucose the glucose that our bodies get!
Where does cellular respiration occur and in what organelle?
Cellular respiration starts in the cytoplasm of the cell, and then enters the mitochondria.
When oxygen is available pyruvate enters the what?
When oxygen is available, pyruvate enters the mitochondria to undergo aerobic respiration. In the mitochondria, pyruvate is converted into acetyl-CoA in the presence of oxygen, leading to the production of ATP through the Krebs cycle and oxidative phosphorylation.
Where does the breakdown of glucose during respiration occurs?
The breakdown of glucose during respiration occurs in the cytoplasm and mitochondria of cells. In the cytoplasm, glycolysis breaks down glucose into pyruvate. Pyruvate then enters the mitochondria where the citric acid cycle and oxidative phosphorylation occur to further break down glucose and produce ATP.
Do pyruvate molecule which is the product of glycolysis enters the mitrochondria during cellular respiration?
Yes, pyruvate molecules produced during glycolysis enter the mitochondria where they undergo further chemical reactions in the citric acid cycle to generate energy in the form of ATP. This process occurs in the matrix of the mitochondria.
Where is anaerobic respiration take place?
The reactions of anaerobic respiration take place in the cytoplasm.
Where does the produced pyruvate go in the second stage of cellular respiration?
In the second stage of cellular respiration, pyruvate is transported into the mitochondria, where it enters the citric acid cycle (also known as the Krebs cycle). Within the citric acid cycle, pyruvate is further broken down to generate energy in the form of ATP.
Why is the mitochondria the site of aerobic cellular respiration?
All the enzymes required for the aerobic respiration(respiration requiring oxygen) are present in mitochondria,thus it always takes place in mitochondria.However,anaerobic respiration takes place in the cytoplasm of cell because all the required enzymes are present in cytoplasm
Where to find cellular respiration in the cell?
Cellular respiration primarily occurs in the mitochondria of eukaryotic cells, where the process converts glucose and oxygen into ATP, carbon dioxide, and water. Glycolysis, the first stage of cellular respiration, takes place in the cytoplasm, breaking down glucose into pyruvate before it enters the mitochondria for further processing. In prokaryotic cells, which lack mitochondria, cellular respiration occurs across the cell membrane.
Where does respiration start?
Respiration starts at the nose and mouth. This is because it is where the oxygen first enters the body in order to be processed.
When purification acid enters the mitrochondria what gas is formed?
When purification acid enters the mitochondria, it can undergo chemical reactions that lead to the formation of toxic gases such as hydrogen sulfide (H2S). This gas can interfere with the functioning of the mitochondria and potentially cause cellular damage.
Where is oxidation of pyruvate located?
The oxidation of pyruvate occurs in the mitochondria of eukaryotic cells. This process is part of cellular respiration and generates acetyl CoA, which then enters the citric acid cycle to produce ATP.
Where in the cell is pyruvate broken down?
Pyruvate is broken down in the mitochondria of the cell through a process called aerobic respiration. Pyruvate is converted into acetyl-CoA, which then enters the citric acid cycle to produce ATP, the cell's main energy source.
