Answer:
nucleus tractus solitarius
Answer: E. exocytosis and it requires expenditure of ATP
Explanation:
Neurotransmitters are molecules released by synaptic pre-neurons and are the means of communication in a chemical synapse. They bind to neurotransmitter receptors and can attach to an ion channel (ionotropic receptors) or an intracellular signaling process (metabotropic receptors). Neurotransmitters are specific for the receptor they bind to and elicit a specific response in postsynaptic neurons, resulting in an excitatory or inhibitory signal. Because exocytosis is an example of active transport, it requires expenditure of ATP.
Question options:
1. Placing a red blood cell in distilled water
2. Placing a red blood cell into an isotonic solution
3. Placing a red blood cell into a hypotonic solution
4. Placing a red blood cell into a hypertonic solution.
5. Placing a red blood cell with a concentration of 0.9% NaCl into a solution of 1.5% NaCl
6. Placing a red blood cell with an ICF concentration of 0.9% NaCl into a solution with 0.1% NaCl.
Answer:
Crenation (shrinking):
-Placing a red blood cell into a hypertonic solution.
-Placing a red blood cell with a concentration of 0.9% NaCl into a solution. of 1.5% NaCl
Hemolysis (swelling):
-Placing a red blood cell in distilled water.
-Placing a red blood cell into a hypotonic solution.
-Placing a red blood cell with an ICF concentration of 0.9% NaCl into a solution with 0.1% NaCl.
No change:
-Placing a red blood cell into an isotonic solution.
Explanation:
Crenation is an osmotic process in which blood cells shrink while placing <u>hypertonic</u> or alkaline solutions. Hemolysis is the destruction of red blood cells in which cells bloat up and may explode while placing in a<u> hypotonic</u> or acidic solution. The blood cells have no change In an <u>isotonic</u> environment because the relative concentrations of solute and water are equal on both sides of the membrane.
