Which are the most stable of cytoskeletal element?
The most stable of the cytoskeletal elements are microtubules and intermediate filaments. Microtubules provide structural support and are involved in intracellular transport and cell division, while intermediate filaments offer mechanical strength and resilience to cells. Unlike actin filaments, which are more dynamic and involved in cell motility, these elements maintain cell integrity and shape over longer periods. Intermediate filaments, in particular, are known for their durability and resistance to depolymerization.
What is the function of Intermediate filament?
Intermediate Filaments (IFs) are part of a cells cytoskeleton along with Microfilaments and Microtubules. Intermediate Filaments are intermediate in size compared to MFs and MTs. They are also more durable and stable than the others. They are mainly used in cellular adhesion and other specialized functions in cells.
What are the cytoskeletal fibers with polarity?
Cytoskeletal fibers with polarity include microtubules and actin filaments. Microtubules have a distinct plus (β-tubulin) and minus (α-tubulin) end, which is crucial for their dynamic instability and directional transport of organelles. Actin filaments also exhibit polarity, with a plus (barbed) end that grows more rapidly and a minus (pointed) end that is more stable. This polarity is essential for various cellular processes, including movement, shape maintenance, and intracellular transport.
What cytoskeletal element are most stable?
Microtubules are considered the most stable cytoskeletal element in the cell. They are composed of tubulin subunits and provide structural support and stability for the cell. Microtubules are involved in various cellular processes, including cell division and intracellular transport.
In the C4 pathway the first stable intermediate is?
The first stable intermediate in the C4 pathway is oxaloacetate. It is involved in capturing carbon dioxide in mesophyll cells to form a 4-carbon compound, which is then transported to bundle-sheath cells for further processing in the Calvin cycle.

What is the first stable intermediate of the C4 pathway?
malate
What would most likely determine the shapes of different types cells-?
The cytoskeleton, particularly actin and the more stable intermediate filaments, are what mainly determines the shape of the cell, along with hydrostatic pressure from the water-containing cytoplasm.
In the C4 pathway the first stable intermediate is?
The first stable intermediate in the C4 pathway is oxaloacetate. It is involved in capturing carbon dioxide in mesophyll cells to form a 4-carbon compound, which is then transported to bundle-sheath cells for further processing in the Calvin cycle.
What is the difference between transition state and intermediate?
A transition state isn't actually a reaction-formed compound or a stable form in any way. It is simply the description of the breaking and forming of bonds via attacking and accepting sites on the reactants. An intermediate indeed is a compound formed by a reaction step, though it is highly reactive and will quickly progress to a more stable form. Because of their instability, intermediates are very tough to isolate, despite being an identifiable compound.
Why is tertiary alcohol more easily oxidized in acid medium than in neutral or alkaline medium?
In acidic medium, the hydroxyl group of the tertiary alcohol can be protonated, making it easier to lose a proton and form a carbocation intermediate, which is more stable due to hyperconjugation. This facilitates the oxidation process compared to in neutral or alkaline medium where the hydroxyl group is not protonated and the carbocation intermediate is less stable.
Is HO compound is covalent?
All bonds between O and H are covalent. OH is not a stable chemical compound it is the hydroxyl radical with one unpaired electron and is a reaction intermediate, OH- is the hydroxide ion, this is stable and ccurs with balancing cations.
What is intermediate between suspensions and solutions?
Emulsions are intermediate between suspensions and solutions. Emulsions are heterogeneous mixtures containing small droplets of one liquid dispersed in another immiscible liquid. They are more stable than suspensions but less uniform than solutions.
