Which statement about myosin is not true? A) Myosin is a heterohexamer. B) Myosin contains two globular heads. C) Myosin contains six different polypeptides D) Myosin aggregates to form thick filaments E) All of the answers above are true of myosin.

Option E, ALL OF THE ANSWERS ABOVE ARE TRUE OF MYOSIN.

Explanation:

Myosins are a superfamily of motor proteins best known for their roles in muscle contraction and in a wide range of other motility processes in eukaryotes.

Muscle myosin is a heterohexamer consisting of two MyHCs and two associated non identical pairs of myosin light chains.

Myosin is a common protein found in the muscles which are responsible for making the muscle contract and relax. It is a large, asymmetric molecule, and has one long tail as well as two globular heads. If dissociated, it will dissociate into six different polypeptide chains. Myosin also aggregates to form thick filaments.

Since all the options on statements about myosin are true, therefore, the option that best suits the question is option E, ALL OF THE ANSWERS ABOVE ARE TRUE about myosin.

marginal cost is a microeconomic measure that us to evaluate the extent to which the level of production of a good is sustainable in accounting, that is, to how many quantities the company plans to profit from the production of the good.

the concept of marginal cost is simple, it means the cost of producing one more item. for example, in the case of pies, the marginal cost is the cost of producing one more pie than those that have already been produced.

it is important to understand that productive activity influences marginal cost. the marginal cost of some goods can be very high, while others may be insignificant. for example, the marginal cost of producing an extra plane is very high. already the marginal cost of a water company to provide 1l more water is derisory.

in the case of pies, the cost involves the inputs, the labor and the fixed cost, which involves the fixed space of the bakery. the level of production initially has the marginal cost decreasing because there is space and manpower available. however, to produce more you have to hire more workers and buy more inputs. if physical space is limited, workers will conflict with places, inputs and their productivity will decrease, meaning there is an optimum point of production for each level of space and manpower. from this point on, the productivity of the workers will be getting smaller because of lack of space, so that the marginal cost of producing one more pie will be increasing. so, although you have not posted the chart, but if you have the answer, you can see that my explanation goes according to the marginal cost curve that will increase from the 4th pie, answer (c).
