Where does Stage 2 of respiration occur?
the mitochondria It is a series of chemical reactions used by all aerobic organisms. In eukaryotes, the second stage of cellular respiration takes place in the matrix of the mitochondria, which plays a major role in the production of ATP molecules within the cells.
What is the second stage of respiration?
The second part of cellular respiration is the Krebs cycle. It takes pyruvate, a molecule produced from glycolysis, and converts it to acetyl-CoA. Acetyl CoA is converted into citric acid, and citric acid is used to make a collection of high-energy intermediates that will ultimately make adenosine triphosphate (ATP).
Where does Stage 2 and 3 of cellular respiration occur?
The second stage of cellular respiration, the Krebs cycle, takes place in the matrix. The third stage, electron transport, takes place on the inner membrane.
Where in the cell do stages 1 and 2 of respiration take place?
In stage one, glucose is broken down in the cytoplasm of the cell in a process called glycolysis. In stage two, the pyruvate molecules are transported into the mitochondria. The mitochondria are the organelles known as the energy "powerhouses" of the cells (Figure below).
Where does each part of cellular respiration occur?
Cellular respiration can occur both aerobically (using oxygen), or anaerobically (without oxygen). During aerobic cellular respiration, glucose reacts with oxygen, forming ATP that can be used by the cell….Aerobic vs anaerobic respiration.
| Aerobic | Anaerobic | |
|---|---|---|
| Location | Cytoplasm (glycolysis) and mitochondria | Cytoplasm |
Where does cellular respiration occur in the mitochondria?
Answer and Explanation: In the mitochondria, cellular respiration occurs in the mitochondrial matrix through the Krebs cycle to form ATP, FADH2 and NADH. The formed FADH2 and NADH then go into the inner mitochondrial membrane where they are involved in the electron transport chain to form more ATP molecules.
Where does the second stage of cellular respiration occur quizlet?
Aerobic respiration second stage occurs in in the inner compartment of the mitochondria. During the reactions, pyruvate is converted to acetyl-CoA which enters the Krebs Cycle.
Where in the cell does cellular respiration take place?
mitochondria While most aerobic respiration (with oxygen) takes place in the cell's mitochondria, and anaerobic respiration (without oxygen) takes place within the cell's cytoplasm.
Where does cellular respiration take place?
mitochondria While most aerobic respiration (with oxygen) takes place in the cell's mitochondria, and anaerobic respiration (without oxygen) takes place within the cell's cytoplasm.
Where does respiration take place in a cell?
mitochondria While most aerobic respiration (with oxygen) takes place in the cell's mitochondria, and anaerobic respiration (without oxygen) takes place within the cell's cytoplasm.
Where does cellular respiration take place in the mitochondria?
The high-energy electrons that are found in the glucose are transferred to the oxygen and potential energy is released. The energy is stored in the form of ATP. This final process of cellular respiration takes place on the inner membrane of the mitochondria.
What are the 4 stages of cellular respiration and where do they occur?
The cellular respiration process includes four basic stages or steps: Glycolysis, which occurs in all organisms, prokaryotic and eukaryotic; the bridge reaction, which stets the stage for aerobic respiration; and the Krebs cycle and the electron transport chain, oxygen-dependent pathways that occur in sequence in the …
What are the three steps of cellular respiration and where do they occur?
1 Answer. BRIAN M. The three main stages of cellular respiration (aerobic) would include Glycolysis in the cytoplasm, the Kreb's Cycle in the Mitochondrial Matrix and the Electron Transport Chain in the Mitochondrial Membrane.
What is the second stage of cellular respiration quizlet?
Krebs Cycle – Second Stage of Cellular Respiration.
What is the second step in aerobic respiration quizlet?
The second stage of aerobic respiration includes glycolysis and the Krebs cycle. All food must be broken down to glucose before ATP can be produced. The true energy payoff for aerobic respiration occurs during electron transfer phosphorylation.
What are the 3 stages of cellular respiration and where do they occur?
1 Answer. BRIAN M. The three main stages of cellular respiration (aerobic) would include Glycolysis in the cytoplasm, the Kreb's Cycle in the Mitochondrial Matrix and the Electron Transport Chain in the Mitochondrial Membrane.
What are the 3 steps of respiration?
Aerobic respiration is divided into three main stages: Glycolysis, Citric acid cycle and Electron transport chain. Glycolysis: Glucose ( 6 carbon atoms) is split into 2 molecules of glyceraldehyde phosphate (3 carbon each), then these are turned into pyruvate (3 carbons each).
What are 3 stages of respiration?
Summary: the three stages of Aerobic Respiration Carbohydrates are broken down using all three stages of respiration (glycolysis, citric acid cycle and the electron transport chain).
Where in the cell does the second stage of cellular respiration take place quizlet?
Where in the cell does the second stage of cellular respiration take place? In the mitochondria.
What is the starting material of the second stage of cellular respiration quizlet?
Second stage of aerobic respiration in which two pyruvate (pyruvic acid) molecules from the first stage react to form ATP, NADH, and FADH2; also known as the citric acid cycle.
What are the 3 steps of cellular respiration and where does each occur?
Cellular respiration is the process in which cells break down glucose, release the stored energy, and use it to make ATP. The process begins in the cytoplasm and is completed in a mitochondrion. Cellular respiration occurs in three stages: glycolysis, the Krebs cycle, and electron transport.
Where does cellular respiration take place in the cell quizlet?
Cellular respiration takes place in mitochondria, which are often called the cell's "powerhouses" because they make most of a cell's ATP. Glycolysis splits glucose into two three-carbon molecules and makes two molecules of ATP. Glycolysis takes place in a cell's cytoplasm and does not need oxygen.
