E) All of the answers are correct.
Ion channels are proteins located in the membrane that allow ions to pass through the channel pore. Ion channels can be classified (by what opens and closes the channels) into few groups:
• Voltage-gated channels-open and close in response to membrane potential
Examples: Voltage-gated proton channels, Voltage-gated sodium channels, Voltage-gated potassium channels
• Ligand-gated (neurotransmitter) or ionotropic receptors (ligand binds to extracellular domain of the receptor
Examples: "nicotinic" Acetylcholine receptor, ionotropic glutamate-gated receptors
• Lipid-gated- lipid molecules bind to the transmembrane domain of the channel
Example: Inward-rectifier potassium channels
• Light-gated channels-like rhodopsin channel that is directly opened by photons
• Mechanosensitive (e.g. stretch, pressure) ion channels.
Answer:
in eukaryotic cells, the cytoplasm includes all of the material inside the cell and outside of the nucleus. All of the organelles in eukaryotic cells, such as the nucleus, endoplasmic reticulum, and mitochondria, are located in the cytoplasm.
Explanation:
Time for microscopes 101. There are two major types of microscopes; light and electron. In a light microscope the image if seen by refracting light through 2 or more lenses which result in a magnified image of the specimen being viewed. However there are limits to the ability to view these and they are not powerful enough to view very small object. An electron microscope which was referred to in the question works by cutting the specimen to be viewed into a very small piece and then bombarding it with electrons which result in a much clearer and more magnified viewing. HOWEVER, Electron microscopes do not work on living things while regular light microscopes do. Also, due to way how electron microscopes are made they are not common in everyday laboratories and are very expensive to buy. comment below if you need anything else
