Action potential is a mechanism of transfer of ions across the plasma membrane down their elctrochemical gradient. Action potential is regenerated by the influx of ions such as sodium in case of voltage gated sodium channels. The voltage gated channels can be either open or closed depending on the action potential. Depolarization of membrane leads to the opening of these channels that allow the sodium ions to enter the cell down their electrochemical gradient. The threshold of action potential is reached when the entry of sodium ions out reach the exit of potassium ions from the cell. This leads to the generation of action potential.
Answer:
Organic molecules have more chemical potential energy than inorganic molecules
Explanation:
Chemical molecules can either be organic or inorganic depending on whether they contain certain elements. Organic molecules are molecules that contain in their structure a carbon-hydrogen bond (C-H) e.g C2H4, C6H12O6 etc. while inorganic compounds do not contain the carbon and hydrogen elements bonded together e.g CO2, H2S
Considering the substances/compounds involved in photosynthesis and respiration, glucose (C6H12O6) is the only organic compound while every other compound is inorganic. However, organic compounds store more potential energy called chemical energy in its C-C or C-H bonds than inorganic molecules do.
Hello,
As a matter of fact, sharks have extremely good eyesight. In fact, they can see surprisingly well in dark lighted areas. Did you know that a shark's eyesight is very similar to a human's eyesight?
Sharks are commonly mistreated as the meanest sea creature in the ocean because of their aggressive appearance. In my opinion, I believe the Killer Whale is the ocean's top killer.
Faith xoxo
The endosymbiotic theory is described that the the primitive eukaryotic cell has ingested a prokaryote to become the mitochondria and the chloroplast. The mitochondria is actually a primitive prokaryote capable of performing cellular respiration. According to this theory, the mitochondria (coming from a primitive prokaryote) must have two membranes, an inner membrane and an outer membrane.
<em>Chloroplasts also have two cell membranes. </em>
