The correct answer is True.
Further Explanation:
The Big Five personality traits are based around the question "who are you?" it is one of the most difficult answers each person answers about themselves.
The factors that are examined in the the Big Five are listed below;
*Openness to experience
*Neuroticism
*Conscientiousness
*Extroversion
*Agreeableness
Robert McCrae and Paul Costa are the two men who did extensive research on the subject and were the first to validate the model. The research duo have been working together since 1975.
The correct answer is (a.) liver. The liver contains the tubules with sinusoids which is lined with macrophages that leads to the central venous structure. A liver is a vital organ that serves as a gland that plays an important role in animal's and vertebrae's metabolism.
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.
This part of the enzyme is known as the active site. Enzymes are organic molecules that catalyze certain chemical reactions in the body. A catalyst is any chemical that speeds up another reaction without being used up in the reaction itself. This means that at the end of the reaction the enzyme is able to operate on other molecules in another reaction.
