Where does Stage 2 of respiration occur?

Stage 2: The Krebs Cycle

The pyruvate molecules from glycolysis next enter the matrix of a mitochondrion. That’s where the second stage of cellular respiration takes place. This stage is called the Krebs cycle.

Where does the second major part of cellular respiration take place?

The citric acid cycle (also known as the Krebs cycle) is the second pathway in cellular respiration and it also takes place in the mitochondria.

Where does the second stage take place?

mitochondrial membranes

The second stage is completed in the mitochondrial membranes. The pyruvate molecules are oxidized to carbon dioxide and 2 carbon acetyl group. Carbon dioxide molecule is released. The 2 carbon acetyl is bound with Co enzyme A and enters to mitochondrial matrix.

What is the second stage of respiration?

The second step in cellular respiration is called the Krebs cycle. The Krebs cycle uses pyruvic acid to create ATP along with additional molecules like NADH FADH2 and CO2.

Where does the second stage of cellular respiration occur WXYZ?

The second stage of cellular respiration the Krebs cycle takes place in the matrix.

Where does cellular respiration take place in the 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.Feb 12 2020

Where does cellular respiration take place in eukaryotic cells?

mitochondria

Glycolysis takes place in the cytoplasm of both prokaryotic and eukaryotic cells. If oxygen is available aerobic respiration will go forward. In eukaryotic cells the pyruvate molecules produced at the end of glycolysis are transported into mitochondria which are the sites of cellular respiration.

What are the three stages of cellular respiration and where do they take place?

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.

Where in cellular respiration is oxygen?

electron transport chain

Oxygen is used as the end electron acceptor for the electron transport chain in cellular respiration. It allows electrons to be transferred through the electron transport chain in order to create an electrochemical gradient for hydrogen to create ATP.

Is energy released in the second stage of cellular respiration?

These two molecules go on to stage II of cellular respiration. The energy needed to split glucose is provided by two molecules of ATP. As glycolysis proceeds energy is released and the energy is used to make four molecules of ATP.

How does the second stage of cellular respiration benefit a cell?

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. In this stage a large amount of energy (ATP molecules) is produced after the complete oxidation of nutrients.

How does cell respiration work?

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. …

Where in the cell does the second stage of respiration take place quizlet?

Terms in this set (5)

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. For two pyruvates the two ATP and ten coenzymes form. All of pyruvate’s carbon dioxide.

Where and how does respiration take place quizlet?

Respiration occurs in the mitochondria and cytoplasm of cells where the conversion of “food” molecules into ATP.

Where in the cell does the first stage of respiration take place quizlet?

Where does the first stage of respiration take place? In the cytoplasm of the cell. What happens in the first stage of respiration? Sugar from food is broken down into smaller particles.

In which of the following anaerobic respiration takes place?

Anaerobic respiration occurs only in the cell cytoplasm. The cytoplasm is the jelly-like substance that occupies the space between the plasma membrane and the nucleus. Glucose is not completely dissolved in anaerobic respiration but much less ATP is released than during aerobic respiration.

Where does each stage of aerobic respiration occur in a eukaryotic cell?

mitochondria
Cellular respiration occurs in both eukaryotic and prokaryotic cells with most reactions taking place in the cytoplasm of prokaryotes and in the mitochondria of eukaryotes. There are three main stages of cellular respiration: glycolysis the citric acid cycle and electron transport/oxidative phosphorylation.May 6 2019

Where does the respiration occur in eukaryotic and prokaryotic cells?

Prokaryotic cells carry out cellular respiration within the cytoplasm or on the inner surfaces of the cells. More emphasis here will be placed on eukaryotic cells where the mitochondria are the site of most of the reactions.

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 occurs in the three stages of cellular respiration?

Lesson Summary. Cellular respiration uses energy in glucose to make ATP. Aerobic (“oxygen-using”) respiration occurs in three stages: glycolysis the Krebs cycle and electron transport. … This results in a net gain of two ATP molecules.

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.

Where in the cell does respiration where oxygen is consumed and carbon dioxide is excreted take place?

In words cellular respiration uses oxygen gas to break apart the carbon-hydrogen bonds in glucose and release their energy to build 38 molecules of ATP. Most of this process occurs within the mitochondria of the cell. Carbon dioxide and water are waste products.

Where does the ETC take place?

The electron transport chain activity takes place in the inner membrane and the space between the inner and outer membrane called the intermembrane space.

Which of the following is released during 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.

Where does photosynthesis take place?

chloroplasts
In plants photosynthesis takes place in chloroplasts which contain the chlorophyll. Chloroplasts are surrounded by a double membrane and contain a third inner membrane called the thylakoid membrane that forms long folds within the organelle.

Which of the following is the second step in getting energy in the cell by breaking down glucose after the glycolysis?

In the second step of glycolysis an isomerase converts glucose-6-phosphate into one of its isomers fructose-6-phosphate. … This is a type of end product inhibition since ATP is the end product of glucose catabolism. Step 4. The newly added high-energy phosphates further destabilize fructose-1 6-bisphosphate.

Which of the following are the stages of respiration in correct order?

breathing gaseous transport tissue respiration and cellular respiration.

What are the stages of respiration explain?

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). This produces 2 ATP and 2 NADH.

What happens in the second stage of aerobic respiration?

Stage two. A pyruvate molecule enters the mitochondria and is broken down in the presence of oxygen to produce carbon dioxide and water. Enough energy is released from each pyruvate molecule to produce a large number of ATP molecules.

Where does aerobic respiration take place quizlet?

Aerobic respiration occurs in the mitochondria of cells. The first reaction to take place is the link reaction. Mitochondria in cells take up the pyruvate which is formed from glycolysis in the cytoplasm.

What happens in the 2 stages of anaerobic respiration?

In the glycolysis the glucose molecule breaks down into two three carbon compound pyruvic acid. In the second stage the pyruvic acid undergoes incomplte oxidation i.e. fermentation. The incompplete oxidation of the pyruvic acid yields ethano or lactic acid.
