Inhoudsopgave
Wat is een lysosoom functie?
Lysosomen zijn organellen, ofwel cellulaire structuren die een bepaalde functie in een cel vervullen. De lysosomen zorgen voor de afbraak van macromolekulen. In elektronenmicroscopische preparaten zien we aan lysosomen weinig bijzondere kenmerken. Alleen de omgevende membraan is altijd aanwezig.
Wat produceert lysosomen?
Het lysosoom is een blaasje dat zich in het cytoplasma bevindt en ook wel “de afvalberg van de cel” genoemd wordt. Lysosomale enzymen in de lysosomen breken afvalstoffen van de cel af, zodat de afbraakproducten hergebruikt of veilig uitgescheiden kunnen worden.
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).
How do mitochondria divide?
Mitochondria divide by mitochondrial fission, a form of binary fission that is also done by bacteria although the process is tightly regulated by the host eukaryotic cell and involves communication between and contact with several other organelles. The regulation of this division differs between eukaryotes.
What is mitochondrial biogenesis?
Mitochondrial biogenesis is in turn temporally coordinated with these cellular processes. Mitochondria have been implicated in several human disorders and conditions, such as mitochondrial diseases, cardiac dysfunction, heart failure and autism. The number of mitochondria in a cell can vary widely by organism, tissue, and cell type.
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.
