Phosphorylation primarily occurs in two forms: substrate-level phosphorylation and oxidative phosphorylation. Substrate-level phosphorylation occurs in the cytoplasm during glycolysis and in the mitochondria during the citric acid cycle, where ATP is produced directly from a substrate. Oxidative phosphorylation takes place in the inner mitochondrial membrane, involving the electron transport chain and chemiosmosis, where ATP is generated indirectly through the flow of protons across the membrane. Additionally, there is protein phosphorylation, which is a regulatory mechanism occurring in various cellular locations, including the cytoplasm and nucleus, where proteins are modified by the addition of phosphate groups, often impacting their activity and function.
What else can I help you with?
What type of phosphorylation does not require a membrane?
Cytoplasmic or soluble enzymes can carry out phosphorylation that does not require a membrane. This type of phosphorylation occurs in the cytoplasm or within organelles like the mitochondria and does not involve a membrane-bound protein complex.
Will phosphorylation denature a protein?
Phosphorylation typically does not denature a protein. Phosphorylation is a reversible modification where a phosphate group is added to a protein, often regulating its function, structure, or localization within the cell. However, extreme or incorrect phosphorylation can lead to protein misfolding and dysfunction.
Where does cellular respiration occur and in what organelle?
Cellular respiration starts in the cytoplasm of the cell, and then enters the mitochondria.
What types of bonds allow different water molecules to be attracted to one another and allows capillary action to occur?
These are hydrogen bonds between water molecules.
What are two methods of phosphorylation?
Two methods of phosphorylation are: Enzyme-catalyzed phosphorylation, where enzymes like kinases transfer phosphate groups from ATP to specific proteins. Photo-phosphorylation, which occurs during photosynthesis where light energy is used to convert ADP and inorganic phosphate into ATP.
What are the two types of phosphorylation that occur during photosynthesis?
Yes. Although the primary function of photosynthesis isn't to create ATP, photophosphorylation does create some ATP molecules which the plants can use in addition to those made in the mitochondria.
What are the different types of fossilization that can occur?
Cast, imprint, amber, and frozen
What are three types of post-translational modification?
methylation lipidation glycosylation phosphorylation
Why different types of volcanoes occur at different places in the world?
Because pressure and temperature varies in different places of the world.
What does repiration occur in?
The mitochondria (pleural), or mitochondrion (s) perform cellular respiration, also known as oxidative phosphorylation.
What are the different types of clots that can occur during a period?
During a period, different types of clots that can occur include small clots, medium-sized clots, and large clots. These clots are typically made up of blood and tissue from the lining of the uterus.
What organelle does repiration occur in?
The mitochondria (pleural), or mitochondrion (s) perform cellular respiration, also known as oxidative phosphorylation.
What type events occur on a genealogy cruise?
Many different types of events occur on genealogy cruises, including conferences, meetings, and dinner dances.
What are the different types of decay that can occur in various materials?
There are several types of decay that can occur in materials, including physical decay (such as wear and tear), chemical decay (such as rusting or corrosion), and biological decay (such as rotting or decomposition).
How do the three types of precipitation occur and what are the different causes?
ummm it just happens , and they are unknown at this point in time.
What are three different types of accidents or sudden illness that may occur in a social care?
accident or sudden illnesses that may occur in a social care setting
In which types of cells does mitosis not occur?
Mitosis does not occur in sex cells, such as sperm and egg cells, as they undergo a different type of cell division called meiosis.
