Excitation-contraction coupling refers to the events that link the action potentials on the sarcolemma to activation of the .

myofilaments

Explanation:

Excitation-contraction coupling is a mechanism by which the electrical signal (action potential) becomes a mechanical action (contraction). This whole situation is made in the presence of calcium which is the chemical messenger necessary for this coupling to occur. Excitation-contraction coupling refers to events that link the action potentials in the sarcolemma to the activation of the myofilaments.

answer: fresh meats are lower in fat than processed meats, and fresh meats are lower in sodium than processed meats.

processed meat has slightly more fat and calories and less protein and cholesterol per serving than unprocessed meat. the biggest nutritional differences between unprocessed and processed red meat are salt (four times more salt in processed meat) and nonsalt preservatives (higher in processed meat)

hope this < 3

the gravitational force on an object increase as the mass of an object also, im not going to report you, but this question should be under the science category, not health
