Biological muscle cells can be thought of as nanomotors that use the chemical energy of ATP to produce mechanical work. Measurem

ents show that the active proteins within a muscle cell (such as myosin and actin) can produce a force of about 8.0 pN and displacements of 8.0 nm. How much work is done by such proteins?

Answer:

The answer is 6.4 × 10^{-20} Joules

Explanation:

This question wants to effectively test your knowledge of the names of the negative powers of 10, so first of all, before calculating, let me explain what each of the symbols in the units given in the question means:

Force = 8.0 pN = 8.0 × 10^{-12} N

displacement = 8.0 nm = 8.0 × 10^{-9} N

Now let us calculate the work.

work = Force × Displacement

work = 8.0 × 10^{-12}  × 8.0 × 10^{-9} = 64 × 10^{-21}

= 6.4 × 10^{20} Joules (in standard form)

Solvency, cohesion, adhesion, hydrogen bonding, chemical reactivity, and thermal stability are all important properties of?
vladimir2022 [97]

Solvency, cohesion, adhesion, hydrogen bonding, chemical reactivity, and thermal stability are all important properties of water.Water has the specific cappotential to dissolve many polar and ionic materials. This is vital to all residing matters because, as water travels thru the water cycle, it takes many precious vitamins along side it! Water has excessive warmness capacity.

Water's enormous functionality to dissolve a lot of molecules has earned it the designation of “regular solvent,” and it's far this cap-potential that makes water such a useful life-maintaining force. On a organic level, water's position as a solvent allows cells shipping and use materials like oxygen or vitamins.

A water molecule has 3 atoms:  hydrogen (H) atoms and one oxygen (O) atom. That's why water is every so often known as H2O. A unmarried drop of water incorporates billions of water molecules.

Which macromolecule forms a double layer as the primary structure of cell membranes?
OlgaM077 [116]
Answer;
Phospholipid.

Phospholipid forms a double layer as the primary structure of cell membranes.

Explanation; 
Cell membranes contains of lipids (phospholipids and cholesterol), proteins and carbohydrates groups that are attached to some of the lipids and proteins. 
Phospholipids are composed of a polar head and non-polar (hydrophobic) tail. They line up such that the heads and the tail groups are side by side to form a single layer due to the interactions between the head groups and the tail groups. Two of these layers line up with the hydrophobic tail groups facing each other to prevent the hydrophobic groups away from the polar head groups of other phospholipids and from the water in the surrounding environment.
