The olfactory receptor cells in the nose are the only sensory receptors that can be replaced throughout life. This neurogenesis allows for the continual renewal of these cells to help maintain our sense of smell.
The image receptors that are not in use are stored elsewhere. The only image receptor that should remain inside the control booth when not in use is the image receptor that will eventually be used.
Only certain cells respond to a specific ligand because they express the appropriate receptor on their cell surface that can bind to the ligand. The binding of the ligand to the receptor triggers a specific signaling pathway within the cell that leads to a response. Cells without the corresponding receptor will not respond to that particular ligand.
receptor sites
Virus attachment is dependent upon the cell surface receptor that can interact with the protein on the virus surface. The interaction is akin to a lock and a key. The key is the protein on the virus, and the lock is the cell surface receptor. A key will only get into the correct lock.
No, chemical transmitters can only stimulate specific receptor sites that they are designed to bind to. Each transmitter has a specific shape that fits into a corresponding receptor site like a lock and key, triggering a specific response in the target cell. This specificity is essential for precise communication between cells in the body.
equilibrum
birds can only see black + white
basically, the viruses have a special compounds on their surface that binds ONLY to a receptor on the liver cell, and its not found on any other cell. so that's is how a virus for hepatitis C for instance ONLY infects the liver. its frankly a receptor ligand interaction
No, all people do not have all senses. If you are blind you have only 4 senses if you are deaf as well you only have 3. Some unfortunate people have none.
dendrites only
Hormones will only interact with its matchingreceptor.
Neurotransmitter receptor sites on ligand-gated ion pores.
Hormones can only be detected by cells that have the specific receptor which binds to the hormone. This means that the hormone only acts on the cells with its receptor and the other cells do not respond.
each hormone receptor only binds to one hormone
only move upwards
Since only 1 neurotransmitter fits in the receptor sites, you can say that the receptor sites is the locked door waiting for the neurotransmitter "keys".
i think its the retina
