Inhoudsopgave
Hoeveel ATP bij gisting?
Alcoholgisting. Ook bij alcoholische gisting ontstaan per glucosemolecuul slechts twee ATP-moleculen, terwijl ethanal (C2) fungeert als laatste waterstofacceptor. Bovendien ontstaan er per glucosemolecuul 2 CO2-moleculen. Ook hiermee wordt lang niet alle in de glucose aanwezige energie vrijgemaakt.
Waar gebeurt citroenzuurcyclus?
Dit proces vindt plaats in de mitochondriën van de cel. De citroenzuurcyclus is een serie van chemische reacties in een kring. Door de citroenzuurcyclus, ook wel krebscyclus genoemd, leveren de eiwitten, vetten en koolhydraten uiteindelijk energie.
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 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 mitochondrial fusion?
Mitochondrial fusion can be divided into two processes, the fusion of the mitochondrial outer membrane followed by that of the inner membrane. The outer membrane fusion requires proteins known as mitofusins, (Mfn1 and Mfn2). Inner membrane fusion mainly involves an inner membrane-localized protein (Opa1).
How are mitochondrial genes synthesized in mitochondria?
These stimuli activate the synthesis of mitochondrial genes, both on mtDNA and nuclear DNA through a series of transcription factors mostly under control of a family of co- activators. (PGC-1alpha, PGC-1beta and PRC).
