I am thinking D. But I am not sure that it is the answer.
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:
<u>lysosomes</u>
Explanation:
They are spherical sac-like organelles that contain lytic enzymes that destroy aged and unwanted cells. They contain hydrolytic enzymes that destroy GM2, gangliosides a class of glycosphingolipid that are produced by the nerve cells. Mutations in the HEXA gene that leads to the translation of hexosaminidase A causes the genetic abnormality, Tay-Sachs.
