Oxytocin and alcohol
Explanation:
Oxytocin helps to relax the muscles of the breasts and induce lactation in a breastfeeding mother. This hormone is commonly called the cuddle hormone since it helps to create the social and emotional bond between the child and the mother.
Alcohol clearly inhibits the secretion of oxytocin and breastfeeding immediately after alcohol consumption can reduce lactation and milk intake by the child. Maintaining an interval after an alcoholic drink again leads to delayed breastfeeding. Intoxicating levels of alcohol in breast milk can affect the child’s health.
Answer:
Shear stress
Explanation:
Shear stress is a type of stress that occurs when a rock mass is pushed in parallel and opposite directions.
Answer:
For both actin and microtubule polymerization, nucleotide hydrolysis is important for decreasing the binding strength between subunits on filaments.
Explanation:
Cytoskeletal filaments are common to eucaryotic cells and are impotartant to the spatial organization of cells. Intermediate filaments provide mechanical strength and resistance to shear stress. Microtubules determine the positions of membrane-enclosed organelles and direct intracellular transport. Actin filaments determine the shape of the cell's surface and are necessary for whole-cell locomotion. A large number of accessory proteins are present that link the filaments to other cell components, as well as to each other. Accessory proteins are essential for the assembly of the cytoskeletal filaments in particular locations, and it includes the motor proteins that either move organelles along the filaments or move the filaments themselves.
Actin filaments and microtubules are assembled with expenditure of energy i.e the ATP/GTP tightly bound to actin/tubulin is irreversibly hydrolyzed to ADP/GTP during the assembly process, and liberation of Pi in the medium occurs subsequent to the incorporation of subunits in the polymer. Pi release acts as a switch, causing the destabilization of protein-protein interactions in the polymer, therefore regulating the dynamics of these fibres. The progress is made in four areas: the chemistry of the NTPase reaction; the structure of the intermediates in nucleotide hydrolysis and the nature of the conformational switch; the regulation of parameters involved in dynamic instability of microtubules; and the possible involvement of nucleotide hydrolysis in the macroscopic organization of these polymers in highly concentrated solutions, compared with the simple case of a equilibrium polymers.
