Answer:
Alpha motor neurons (also called lower motor neurons) innervate skeletal muscle and cause the muscle contractions that generate movement. Motor neurons release the neurotransmitter acetylcholine at a synapse called the neuromuscular junction.
Answer:
The correct list of compartments glucose enter is :
The lumen > plasma (extracellular fluid) > interstitial fluid (extracellular fluid) > the skeletal muscle cell (intracellular fluid)
Explanation:
The glucose molecule would start from the lumen of the intestine where is absorbed. The glucose enters the plasma a part of the circulatory system known as extracellular fluid.
The glucose also encounters another type of extracellular fluid the interstitial fluid that is not in the circulatory system. At the last glucose as it is entering the skeletal muscle cell the last fluid compartment, which is intracellular fluid. This fluid is inside the cells.
Answer:
While <u>water soluble</u> hormones can travel freely in the blood, <u>lipid soluble </u>hormones require a carrier protein because they are not soluble in the aqueous plasma
Explanation:
The water-soluble hormones such as insulin are dissolved in the blood and are carried along with the blood to their target cells.
However, lipid-soluble hormones such as steroid hormones (cortisol) and thyroxine are hydrophobic in nature. These hormones are not dissolved in water-based blood plasma. So, these lipid-soluble hormones are carried through the carrier proteins.
No because a chemical reaction that is at equilibrium in living cells is not capable of doing any work
