What molecules do mitochondria produce?
adenosine triphosphate (ATP)
Chemical energy produced by the mitochondria is stored in a small molecule called adenosine triphosphate (ATP).
Does mitochondria synthesize and store energy?
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). In ATP the energy is stored in the form of chemical bonds.
How does mitochondria work with other organelles?
The mitochondria, termed the “powerhouse” of the cell, works with other cellular organelles by providing them with the major form of energy know as adenosine triphosphate (ATP). ATP allows other cellular organelles to function properly maintaing the integrity of the cell.
In which part of mitochondria ATP is synthesized?
inner membrane
Hint: The ATP synthesis occurs within the fold in the inner membrane of a mitochondrion. The passage of energy-rich electrons among cytochromes and coenzymes drains the energy from the electrons to make ATP from ADP and phosphate ions.
What is the principal role of the mitochondria in cells?
Mitochondria play a critical role in the generation of metabolic energy in eukaryotic cells. As reviewed in Chapter 2, they are responsible for most of the useful energy derived from the breakdown of carbohydrates and fatty acids, which is converted to ATP by the process of oxidative phosphorylation.
Does the mitochondria synthesize ATP?
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.
What is the role of mitochondria in ATP synthesis?
The classic role of mitochondria is oxidative phosphorylation, which generates ATP by utilizing the energy released during the oxidation of the food we eat. The proton-motive force set up by this proton pumping drives protons back into the mitochondrial matrix through the ATP synthase to generate ATP.
