Carbon dioxide + Water Glucose (sugar) + Oxygen CO2 + H2O C6H12O6 + 6O2 Cellular respiration or aerobic respiration is a series of chemical reactions which begin with the reactants of sugar in the presence of oxygen to produce carbon dioxide and water as waste products.

Where is carbon dioxide produced in the mitochondrion?

Within the central compartment of the inner mitochondrial membrane are the Krebs cycle enzymes that, in a cyclical series of chemical reactions, break down the two-carbon fragments to carbon dioxide. As part of these breakdown reactions high energy electrons are produced.

What is the mitochondria function?

Mitochondria are membrane-bound cell organelles (mitochondrion, singular) that generate most of the chemical energy needed to power the cell’s biochemical reactions. Chemical energy produced by the mitochondria is stored in a small molecule called adenosine triphosphate (ATP).

What occurs in the mitochondrion?

Known as the “powerhouses of the cell,” mitochondria produce the energy necessary for the cell’s survival and functioning. Through a series of chemical reactions, mitochondria break down glucose into an energy molecule known as adenosine triphosphate (ATP), which is used to fuel various other cellular processes.

Which process occurs within the mitochondria quizlet?

Which process occurs within the mitochondria? Krebs cycle.

Which process occurs within the mitochondria Brainly?

The process is called oxidative phosphorylation and it happens inside mitochondria. In the matrix of mitochondria the reactions known as the citric acid or Krebs cycle produce a chemical called NADH. NADH is then used by enzymes embedded in the mitochondrial inner membrane to generate adenosine triphosphate (ATP).

When and how do cells store energy?

Living organisms use two major types of energy storage. Energy-rich molecules such as glycogen and triglycerides store energy in the form of covalent chemical bonds. Cells synthesize such molecules and store them for later release of the energy.

How do cells store energy?

Cells store energy in the form of ATP, or adenosine triphosphate. ATP is a molecule produced as a result of cellular respiration, and storing energy…

How does ATP store energy?

ATP (adenosine triphosphate) stores energy in its high energy phosphate bonds. ATP consists of an adenosine molecule bonded to three phosphate groups in a row. During cellular respiration, energy in food is converted into chemical energy that can be used by cells.

Which equation shows a chemical reaction that occurs during anaerobic cell respiration?

Some examples of anaerobic respiration include alcohol fermentation, lactic acid fermentation and in decomposition of organic matter. The equation is: glucose + enzymes = carbon dioxide + ethanol / lactic acid.

What is cellular respiration quizlet?

cellular respiration definition. The process of converting glucose into a form of energy (ATP) that is useable by cells. glycolysis. Begins initial breakdown of glucose. Occurs in the cytoplasm.

Where does cellular respiration occur?

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 is carbon dioxide produced?

Carbon dioxide is produced during the processes of decay of organic materials and the fermentation of sugars in bread, beer and wine making. It is produced by combustion of wood, peat and other organic materials and fossil fuels such as coal, petroleum and natural gas.

Where is carbon dioxide produced in the cell?

In mitochondria, this process uses oxygen and produces carbon dioxide as a waste product.

What process occurs in the chloroplast what is needed what is produced?

In plants and algae, which developed much later, photosynthesis occurs in a specialized intracellular organelle—the chloroplast. Chloroplasts perform photosynthesis during the daylight hours. The immediate products of photosynthesis, NADPH and ATP, are used by the photosynthetic cells to produce many organic molecules.

Why mitochondria is a cell within a cell?

Mitochondria are tiny organelles inside cells that are involved in releasing energy from food. … It is for this reason that mitochondria are often referred to as the powerhouses of the cell. Cells that need a lot of energy, like muscle cells, can contain thousands of mitochondria.

What does the mitochondrion do in a plant cell?

Mitochondria carry out a variety of important processes in plants. Their major role is the synthesis of ATP through the coupling of a membrane potential to the transfer of electrons from NADH to O2 via the electron transport chain.

How does the mitochondria produce energy for the cell answers?

Mitochondria are the powerhouses of the cell because they “burn” or break the chemical bonds of glucose to release energy to do work in a cell. … This releases energy for the cell. ATP is the energy-carrying molecule produced by the mitochondria through a series of chemical reactions.

What is the main function of the mitochondrion in cellular respiration?

The main function of mitochondria is to produce energy through aerobic respiration. Principal fuels for ATP generation are fatty acids and glucose.

In which two parts of a mitochondrion does cellular respiration take place?

The mitochondrion has an inner and outer membrane separated by an intermembrane space, and the inner membrane encloses a space called the matrix. The second stage of cellular respiration, called the Krebs cycle , takes place in the matrix of a mitochondrion.

What happens in the mitochondrial matrix?

In the mitochondrion, the matrix is the space within the inner membrane. … The enzymes in the matrix facilitate reactions responsible for the production of ATP, such as the citric acid cycle, oxidative phosphorylation, oxidation of pyruvate, and the beta oxidation of fatty acids.

Which process occurs in the inner membrane of the mitochondrion?

The electron transport chain is the final step in cellular respiration. It uses the electron carrier molecules NADH and FADH2 created during the Krebs cycle. This process occurs along the inner membrane of your mitochondria.

Which of the following process occurs in the inner membrane of the mitochondrion?

The inner mitochondrial membrane transduces energy through oxidative phosphorylation, the main process responsible for the production of energy in the form of ATP in eukaryotic cells (Saraste, 1999).

Which stages occur in the mitochondria?

In general, cellular respiration can be divided into four stages: Glycolysis, which does not require oxygen and occurs in the mitochondria of all cells, and the three stages of aerobic respiration, all of which occur in mitochondria: the bridge (or transition) reaction, the Krebs cycle and the electron transport chain …

What is the main transformation that occurs during glycolysis?

During glycolysis, glucose is broken down into two molecules of pyruvate. What is the main transformation during glycolysis? Glycolysis produces pyruvate, ATP, and NADPH by oxidizing glucose. During cellular respiration, glucose combines with oxygen to form carbon dioxide, water, and ATP.

What are the two main stages of the cell cycle check all that apply?

The answer is interphase and mitosis.

Which is the final electron acceptor in the electron transport chain of cellular respiration?

Explanation: In cellular respiration, oxygen is the final electron acceptor. Oxygen accepts the electrons after they have passed through the electron transport chain and ATPase, the enzyme responsible for creating high-energy ATP molecules.

How is the stored energy released and used up?

In a process called cellular respiration, chemical energy in food is converted into chemical energy that the cell can use, and stores it in molecules of ATP. … When the cell needs energy to do work, ATP loses its 3rd phosphate group, releasing energy stored in the bond that the cell can use to do work.

Where is chemical energy stored?

Chemical energy is energy stored in the bonds of atoms and molecules. Batteries, biomass, petroleum, natural gas, and coal are examples of chemical energy.

How do cells store energy from glucose?

The process can be summarized as: glucose + oxygen → carbon dioxide + water. During this process, the energy stored in glucose is transferred to ATP. Energy is stored in the bonds between the phosphate groups (PO4) of the ATP molecule.

How is chemical energy stored in photosynthesis?

Photosynthesis is the process plants and some algae use to convert light energy to chemical energy stored as sugar within chloroplasts — the energy factories found in plant cells. … Energy stored during photosynthesis begins the flow of energy and carbon down the food chain.
