So this one is talking about the three cytoskeletal elements and their associated motor proteins.

Describe the motion that occurs: 1. when the molecular motor is locked into position, but the cytoskeleton is not. 2. the cytoskeletal element is locked into position but the motor is not. And 3. when the both are locked into position.

A mutant of Myosin V is created that cannot unbind ADP. The ADP is essentially stuck. Describe the interaction that would take place between that mutant myosin protein and the actin microfilament.

They help the cell remain rigid but also help it move and change its shape when instructed to do so. Components of the cytoskeleton also enable cilia, flagella and sperm to move, cell organelles to be moved and positioned, and muscles to function. ... This image shows some animal cells.

Due to cytoskeleton , cell is able to retain it;s shape. Without cytoskeletan cell will no longer be able to retain its shape and will ultimately burst

Powering chromosome movement (microtubules) The most prominent structure in a mitotic cell is the bipolar spindle (made up of microtubules and associated motor proteins), which provides the force to move chromosomes and thereby bring about their segregation

The cytoskeleton causes many cardiovascular diseases, neurodegeneration, cancer, cirrhosis, and even skin diseases! ... This disease is characterized by swollen hands and feet, spleen damage, delayed growth in youth, and vison problems.

Muscle contraction thus results from an interaction between the actin and myosin filaments that generates their movement relative to one another. The molecular basis for this interaction is the binding of myosin to actin filaments, allowing myosin to function as a motor that drives filament sliding.

What prevents the actin subunits in cells from polymerizing into filaments? ... In cells, most of the actin subunits are bound to thymosin, which locks actin into a form that cannot hydrolyze its bound ATP and cannot be added to either end of a filament.

so far we have been talking about businesses and profits. But, is knowing the break-even point important only to for-profit businesses? Do non-profit entities also need to know their break-even point (if they don't make a profit)? If yes, why? Can you explain with an example? (does not need to involve numbers) [For example, Adelphi University is a nonprofit entity. Does it need to at least breakeven each year? If so, why?]
