Where Does Most Atp Production Take Place Within A Cell


Where Does Most Atp Production Take Place Within A Cell?

Most of the ATP in cells is produced by the enzyme ATP synthase which converts ADP and phosphate to ATP. ATP synthase is located in the membrane of cellular structures called mitochondria in plant cells the enzyme also is found in chloroplasts.

Where does ATP production occur in the mitochondria?

Most of the adenosine triphosphate (ATP) synthesized during glucose metabolism is produced in the mitochondria through oxidative phosphorylation. This is a complex reaction powered by the proton gradient across the mitochondrial inner membrane which is generated by mitochondrial respiration.

Which cell contain the most ATP?

The large amount of energy released is harnessed by the inner membrane to drive the conversion of ADP + Pi to ATP. For this reason the term oxidative phosphorylation is used to describe this last series of reactions (Figure 14-11).

What is the primary site of ATP production in a cell?


Most eukaryotic cells contain many mitochondria which occupy up to 25 percent of the volume of the cytoplasm. These complex organelles the main sites of ATP production during aerobic metabolism are among the largest organelles generally exceeded in size only by the nucleus vacuoles and chloroplasts.

Is ATP only produced in mitochondria?

The ATP is produced in the mitochondria using energy stored in food. … All living cells above the level of microbes have mitochondria. Hair cells and outer skin cells are dead cells and no longer actively producing ATP but all cells have the same structure. Some cells have more mitochondria than others.

What process takes place within mitochondria?

Mitochondria using oxygen available within the cell convert chemical energy from food in the cell to energy in a form usable to the host cell. The process is called oxidative phosphorylation and it happens inside mitochondria. … In ATP the energy is stored in the form of chemical bonds.

Where does cellular respiration take place in 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.

Where is ATP produced?

Most of the ATP in cells is produced by the enzyme ATP synthase which converts ADP and phosphate to ATP. ATP synthase is located in the membrane of cellular structures called mitochondria in plant cells the enzyme also is found in chloroplasts.

In which part of the cell does the process take place?


Most cellular activities take place within the cytoplasm such as many metabolic pathways including glycolysis and processes such as cell division. The concentrated inner area is called the endoplasm and the outer layer is called the cell cortex or the ectoplasm.

Where is the energy stored in ATP?

Adenosine Triphosphate

Energy is stored in the bonds joining the phosphate groups (yellow). The covalent bond holding the third phosphate group carries about 7 300 calories of energy.

What is the most likely pathway taken by a newly synthesized proteins that will be secreted by a cell?

The most common secretion pathway is the secretory pathway (Figure 1). Newly synthetized proteins are transported from the endoplasmic reticulum (ER) passing the Golgi apparatus and packed into vesicles. The vesicles are then transported to the plasma membrane.

Which organelle is the site of ATP production?

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 is the primary site of cellular respiration?

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.

When and where ATP is produced?

The majority of ATP synthesis occurs in cellular respiration within the mitochondrial matrix: generating approximately thirty-two ATP molecules per molecule of glucose that is oxidized.

Which stage of cellular respiration produces the most ATP?

The Krebs cycle takes place inside the mitochondria. The Krebs cycle produces the CO2 that you breath out. This stage produces most of the energy ( 34 ATP molecules compared to only 2 ATP for glycolysis and 2 ATP for Krebs cycle).

How does ATP get out of the mitochondria?

Mitochondrial ADP/ATP carriers transport ADP into the mitochondrial matrix for ATP synthesis and ATP out to fuel the cell by cycling between cytoplasmic-open and matrix-open states. … The cytoplasmic side of the carrier is closed by conserved hydrophobic residues and a salt bridge network braced by tyrosines.

Which process occurs inside the mitochondria quizlet?

Which process occurs within the mitochondria? Krebs cycle.

Why does cellular respiration take place in the mitochondria?

Cellular respiration takes place (mainly) in the mitochondria because it is the cell’s “powerhouse”. It is where the energy (ATP) is produced in the cell and the process of cellular respiration is the way the cells form that energy.

How is ATP produced in cellular respiration?

Most of the ATP produced by aerobic cellular respiration is made by oxidative phosphorylation. The energy of O2 released is used to create a chemiosmotic potential by pumping protons across a membrane. This potential is then used to drive ATP synthase and produce ATP from ADP and a phosphate group.

What happens inside the mitochondria during cellular respiration?

Cellular respiration is the process of making ATP using the chemical energy found in glucose and other nutrients. In mitochondria this process uses oxygen and produces carbon dioxide as a waste product. … Instead the small amount of ATP they make in the absence of oxygen is accompanied by the production of lactic acid.

Where is most of the ATP generated during aerobic respiration?

The electron transport chain

Explanation: The electron transport chain generates the most ATP out of all three major phases of cellular respiration.

What is the role of ATP in the cell?

Adenosine 5′-triphosphate or ATP is the principal molecule for storing and transferring energy in cells. It is often referred to as the energy currency of the cell and can be compared to storing money in a bank.

What is the main source of ATP?

In general the main energy source for cellular metabolism is glucose which is catabolized in the three subsequent processes—glycolysis tricarboxylic acid cycle (TCA or Krebs cycle) and finally oxidative phosphorylation—to produce ATP.

Which is the most important part of the cell?

1. The nucleus is the most vital organelle within the cell. It contains the genetic material the DNA which is liable for controlling and directing all the activities of the cell. All the RNAs needed for the cell are synthesised within the nucleus.

Which process can produce the most energy for a cell?

cell respiration

Eukaryotic cells use their mitochondria to generate ATP through a process called cell respiration. Respiration that uses oxygen is called aerobic respiration while oxygen-less respiration is called anaerobic respiration.

In which part of the cell does the process take place in glycolysis Brainly?

Glycolysis. Glycolysis is the first pathway in cellular respiration. This pathway is anaerobic and takes place in the cytoplasm of the cell.

Where is most of the energy stored in an ATP molecule to do work in the body?

Energy is stored in the bonds between the phosphate groups (PO4) of the ATP molecule. When ATP is broken down into ADP (adenosine diphosphate) and inorganic phosphate energy is released.

Where do you find the most potential energy in the ATP molecule?

The potential energy in an ATP molecule is derived mainly from its three phosphate groups. The three phosphate groups in an ATP molecule carry negative charges that strongly repel each other and give ATP a large amount of potential energy.

Where is energy stored?

Mechanical energy is energy stored in objects by tension. Compressed springs and stretched rubber bands are examples of stored mechanical energy. Nuclear energy is energy stored in the nucleus of an atom—the energy that holds the nucleus together.

What is the most likely path for a protein is that is synthesized and secreted outside the cell quizlet?

Proteins to be secreted outside of a cell are synthesized on ribosomes bound to the endoplasmic reticulum then sent to the Golgi apparatus for modification and sorting. Finally the proteins are packaged into a vesicle that fuses with the plasma membrane releasing the proteins outside of the cell.

Where does protein synthesis take place?


Ribosomes are the sites in a cell in which protein synthesis takes place.

How are proteins transported to their correct locations in the cell?

How are proteins transported to their correct location in the cell? … Proteins contain molecular “zip codes” that allow them to be shipped to the correct cellular compartment. Correct. For example proteins destined for the nucleus contain a nuclear localization signal and other proteins contain an ER signal sequence.

Is Site for energy ATP production of cell?

The mitochondria

A) This is the correct answer. The mitochondria is the cell’s primary site of ATP production accomplished through oxidative phosphorylation.

Where do the organelles reside in the cell?

Inside the cell there is a large fluid-filled space called the cytoplasm sometimes called the cytosol. In prokaryotes this space is relatively free of compartments. In eukaryotes the cytosol is the “soup” within which all of the cell’s organelles reside.
