Id say trick question it doesn't. Or, id say, it helps you realize how much to eat and what times you should be eating.
Answer: True
Explanation: Like all living things, prokaryotes need energy and carbon. They get energy from inorganic chemical compounds.
Chemoautotrophs are organism that utilizes inorganic molecules to supply energy for the organism, and use carbon dioxide as a carbon source. Chemoautotrophs are mostly prokaryotes that break down hydrogen sulfide and ammonia.
Most Eukaryotes cannot utilize these inorganic molecules as energy source.
The nerve impulse would not be transmitted
* Channel proteins- these are proteins with a hydrophilic pore where specific ions are able to pass through the membrane. Each channel protein is specific to an ion. This is the only way ions can travel through the membrane. They are trans membrane proteins.
* Carrier proteins- these are proteins which allow larger or polar molecules through the membrane. They are trans membrane proteins.
Carrier proteins essentially “carry" signals that are not soluble in aqueous solution through the blood stream to their target cells. Carrier proteins for hydrophilic signals prevent degradation of the signal. Channel proteins are embedded in cell membranes. They often are receptors (though not always), and when activated, allow specific ions to pass through the membrane.
A channel protein is a special arrangement of amino acids which embeds in the cell membrane, providing a hydrophilic passageway for water and small, polar ions. Like all transport proteins, each channel protein has a size and shape which excludes all but the most specific molecules
The carrier protein facilitate diffusion of molecules across the cell membrane. The protein is imbedded in the cell membrane and covers the entire membrane. This is important because the carrier must transport the molecule in and out of the cell.
