Waar bevinden zich mitochondriën?
De meeste lichaamscellen bevatten 500 tot 2.000 mitochondrieën. Mitochondrieën of mitochondria is het meervoud van mitochondrion. Een mitochondrion is ovaal van vorm. Grote aantallen mitochondrieën zijn te vinden in organen die veel energie nodig hebben, zoals de hersenen, het hart, de lever en de skeletspieren.
Waar vind oxidatieve fosforylering plaats?
In de binnenmembranen van mitochondriën vindt oxidatieve fosforyerling plaats. Producten uit de citroenzuurcyclus, zoals NADH, leveren elektronen af aan de elektronentransportketen. Eiwitcomplexen zullen de elektronen doorgeven en daarbij H+-ionen (protonen) over het membraan pompen.
What are mitochondria?
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 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 stored in mitochondria?
Chemical energy produced by the mitochondria is stored in a small molecule called adenosine triphosphate (ATP). Mitochondria contain their own small chromosomes. Generally, mitochondria, and therefore mitochondrial DNA, are inherited only from the mother.
What is the electron transport system of mitochondria?
The Electron Transport System of Mitochondria Embedded in the inner membrane are proteins and complexes of molecules that are involved in the process called electron transport. The electron transport system (ETS), as it is called, accepts energy from carriers in the matrix and stores it to a form that can be used to phosphorylate ADP.
