Letter B is single stranded binding proteins
Skeletal muscle contractions do in fact demand large quantities of ATP (adenosine triphosphate), the universal source of cellular energy. In order to accommodate this necessity, skeletal muscle cells (myocytes) are packed with mitochondria, which are the energy powerhouses of the cell.
However, the production of ATP would halt in mitochondria if the necessary substrates (fuels) are not present to enter these organelles, mainly glucose and oxygen (O2). So, additionally, skeletal muscle is also loaded with glycogen, a storage form for glucose (as starch), and myoglobin, an enzyme similar to hemoglobin in that it binds an O2 to hold it for use during contraction.
Answer:
A(the first one)
Explanation:
Homeostasis maintains the constant internal conditions in an organism. It is important because cells function best with a limited range of conditions. ... All living things have body parts with different functions that help them survive.
Force = Mass * Acceleration ........................ (that is all know)
<span>Force is given= 3200N </span>
<span>Mass is= 160 Kg </span>
<span>Acceleration= ? </span>
<span>F = M*A </span>
<span>F/M=A </span>
<span>3200/160=A </span>
<span>A=20m/s^2</span>
