What is mitochondria?
“Mitochondria are membrane-bound organelles present in the cytoplasm of all eukaryotic cells, that produces adinosine triphosphate (ATP), the main energy molecule used by the cell.” Read on to explore what is mitochondria, its structure, and functions. What is Mitochondria?
What is the function of the membranes of mitochondria?
Those membranes function in the purpose of mitochondria, which is essentially to produce energy. That energy is produced by having chemicals within the cell go through pathways, in other words, be converted.
What is the role of mitochondria in energy metabolism?
INTRODUCTION Mitochondria are now known to be more than the hub of energy metabolism. They are the central executioner of cells, and control cellular homeostasis through involvement in nearly all aspects of metabolism.
What is the role of mitochondria in apoptosis?
It also plays a major role in apoptosis or cellular suicide. During apoptosis, a cell does not die of an injury but a series of chemical reactions leading to the elimination of the cell.
What are mitochondria and cristae?
Mitochondria are the cell organelles that are responsible for producing ATP, the energy currency of the cell. 3. Briefly describe the structure of mitochondria. Mitochondria is a rod-shaped, double membraned organelle. It is found both in plant cells and animal cells. 4. What are cristae? The inner membrane of mitochondria has many folds.
What is the role of mitochondria in homeostasis?
Mitochondria are involved in processes like cell signaling, cell growth, apoptosis. Mitochondria has reserves of free calcium, which regulates a series of chemical reactions. It also maintains homeostasis within the cell, by heat production.
What is the structure and function of mitochondrial matrix?
The mitochondrial matrix is a viscous fluid that contains a mixture of enzymes and proteins. It also comprises ribosomes, inorganic ions, mitochondrial DNA, nucleotide cofactors, and organic molecules. The enzymes present in the matrix play an important role in the synthesis of ATP molecules. Function of Mitochondria.
