HELP ASAP!!QUESTION 2 How does hydrolysis of ATP associated with Bera-tubulin affect the assembly of microtubule protofilaments?
ATP does not bind beta-tubulin and therefore does not affect on the formation of microtubule protofilaments.
ATP hydrolysis changes the conformation of the tubulin heterodimer, which weakens the bonds between the tubulin heterodimers to destabilize
the protofilament
ATP hydrolysis promotes the assemble of the microtubule organizing center.
ATP hydrolysis phosphorylates Tau, which stabilizes microtubules.

answer: - b cells

explanation: -

there are many types of white blood cells present in our body. one such class of white blood cells are the lymphocytes. the b cells belong to the lymphocyte class of wbcs. the b cells perform their action against the pathogen by producing specialised proteins called as antibodies. these antibodies are produced as and when the b cells encounter pathogens in response to the antigens present on the surface of the pathogen. these antibodies bind to the antigens present on the pathogen and then, target them for destruction by other cells of the immune system.

so, the b cells mediate their action by identifying the antigens present on the surface of the pathogens and then producing antibodies in return to mediate its effect.

The type of bond found in many carbon-to-carbon bonds in canola oil but very few carbon-to-carbon bonds in butter, is ; c=cc-c c=c c=h c-h hope this .
