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.

How does the mitochondria generate ATP?

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. … NADH is then used by enzymes embedded in the mitochondrial inner membrane to generate adenosine triphosphate (ATP).

How is ATP production controlled by the cell?

Explain how ATP production is controlled by the cell. … Phosphofructokinase is an enzyme that catalyzes the transfer of a phosphate from ATP to fructose-6-phosphate. PFK is the key regulatory enzyme for glycolysis that stops the flow of carbohydrates. It is inhibited by high levels of ATP.

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.

What is the site of ATP production in 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.

Is the site of cellular respiration and the production of ATP?

The Location of Cellular Respiration

Glycolysis takes place in the cytosol whereas pyruvate oxidation the Krebs cycle and oxidative phosphorylation occur in the mitochondrion. … The energy produced by the mitochondria is stored as potential energy in molecules called adenosine triphosphate (ATP).

What part of the mitochondria is the specific site for ATP production?

inner membrane
The inner membrane is also loaded with proteins involved in electron transport and ATP synthesis. This membrane surrounds the mitochondrial matrix where the citric acid cycle produces the electrons that travel from one protein complex to the next in the inner membrane.

How do mitochondria supply energy to the cell?

Mitochondria are organelles – ‘small organs’ within each cell. They produce energy in the form of a molecule called ATP (adenosine triphosphate) which gets used throughout the cell to power the different jobs it has to do. … As they do so energy is extracted and transferred into ATP.

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).

Where does mitochondria get its energy from?

Mitochondria produce energy through the process of cellular respiration. The mitochondria take food molecules in the form of carbohydrates and combine them with oxygen to produce the ATP. They use proteins called enzymes to produce the correct chemical reaction.

Where do respiration and cellular respiration takes place?

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 the electron transport chain take place?


The electron transport chain is a series of four protein complexes that couple redox reactions creating an electrochemical gradient that leads to the creation of ATP in a complete system named oxidative phosphorylation. It occurs in mitochondria in both cellular respiration and photosynthesis.

What is the most common mechanism that regulates cellular respiration in most cells?

What is the most common mechanism that regulates cellular respiration in most cells? Fermentation by itself produces no ATP but keeps glycolysis going which produces a small amount of ATP. How does fermentation do this? Fermentation oxidizes NADH to NAD+ which facilitates the production of ATP in glycolysis.

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.

In which of the following steps synthesis of ATP takes place?

In order to understand the mechanism by which the energy released during respiration is conserved as ATP it is necessary to appreciate the structural features of mitochondria. These are organelles in animal and plant cells in which oxidative phosphorylation takes place.

What are mitochondria the site of?

Mitochondria are the cellular sites of respiration energy production and some aspects of calcium handling.

What part of cellular respiration takes place in 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 …

Where does the final stage of cellular respiration take place?

the mitochondrion
The third and final stage of cellular respiration called electron transport takes place on the inner membrane of the mitochondrion. Electrons are transported from molecule to molecule down an electron-transport chain.

What happens to most of the energy released during cellular respiration?

Summary. Through the process of cellular respiration the energy in food is converted into energy that can be used by the body’s cells. During cellular respiration glucose and oxygen are converted into carbon dioxide and water and the energy is transferred to ATP.

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 event takes place in the electron transport chain?

In the electron transport chain electrons are passed from one molecule to another and energy released in these electron transfers is used to form an electrochemical gradient. In chemiosmosis the energy stored in the gradient is used to make ATP.

Where are mitochondria located?

Mitochondria are structures within cells that convert the energy from food into a form that cells can use. Each cell contains hundreds to thousands of mitochondria which are located in the fluid that surrounds the nucleus (the cytoplasm).

Where is energy produced in a cell?


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).

How do mitochondria move around the cell?

Mitochondria primarily move by the action of molecular motors along cytoskeletal elements (Figure 2 and Table 1). Like other organelles mitochondria associate with specific motor isoforms through organelle-specific adaptors and their movement is sensitive to disruption of these motors and adaptor proteins.
