ATP
Glycerinated muscle requires the addition of ATP (adenosine triphosphate) to supply the energy needed for muscle contraction. ATP is essential for the cross-bridge cycling process that allows muscle fibers to contract.
Active transport requires energy to move a molecule.
Excitation-contraction coupling in muscle cells requires the propagation of an action potential along the sarcolemma, which triggers the release of calcium ions from the sarcoplasmic reticulum. The binding of calcium ions to troponin exposes binding sites on actin, allowing myosin to bind and initiate muscle contraction.
It requires energy, and a protein carrier molecule. The large particle binds to the protein carrier on the inside of the cell. It is then transported across the membrane as a result of a conformational change in the protein (think of it flipping), and then it is released on the outside of the cell. Again, this requires some source of energy.
Conduction requires the presence of matter. The way conduction works, one atom or molecule bumps into another one, transferring heat energy.
Lifting an object against gravity requires more force than pulling it along a horizontal surface because you are working against the force of gravity. When lifting, you are fighting against the weight of the object in addition to any other resistance present, such as friction. Pulling, on the other hand, only requires overcoming the frictional force.
Anerobic contraction of muscles.
No it freaking is false :d
Active transport requires energy to move a molecule.
Active transport requires energy to move a molecule.
Ca2+ and ATP
There's is a contraction of "there is" and requires an apostrophe.
Active transport requires energy to move a molecule.
A semipermeable membrane is a large glucose molecule that requires facilitated diffusion but an oxygen molecule does not.
Heat. Also, pass an electrical current through water by submerging a Cathode and an Anode. It requires the addition of 118kJ of energy per H2O molecule
A large glucose molecule requires facilitated diffusion but an oxygen molecule does not is a semipermeable membrane.

Inhalation requires the contraction of the diaphragm, and exhalation occurs when it relaxes.
