Answer;
-In the smooth ER
In certain kinds of muscle cells, calcium ions are stored in the smooth ER.
Explanation;
-The smooth endoplasmic reticulum is the part of the endoplasmic reticulum (ER) which does not have ribosomes bound to it, thus not exhibiting the bumpy appearance shown by the rough endoplasmic reticulum.
-The smooth ER is important in the synthesis of lipids, such as cholesterol and phospholipids, which form all the membranes of the organism. In addition it is important for the synthesis and secretion of steroid hormones from cholesterol and other lipid precursors.
Answer:
5- action potential 6- receptors 7- calcium ions 8- sarcolemma
Explanation:
This description illustrates the pathway of a action potential traveling along a neuro-muscular junction. this functions as a chemical synapse between a motor neuron and a muscle fibre. It allow the motor neuron to transmit a signal/action potential to the muscle fiber, causing muscle contraction.
Answer:
The answer is D. Calcium
Explanation:
The Electrolyte, according to the reference table in the question, which focuses mainly outside the body's cells is Calcium. Calcium has a value of 8 to 10 mEq / l in the extracellular fluid and 0.01 mg in the intracellular fluid. It is an electrolyte with positive charge: Ca ++.
I really don't know how to help you here, bud.
