What are the functions of attachment proteins that attach to specific receptors on cells?
Attachment proteins play a crucial role in attaching to specific receptors on cells, facilitating cell communication, signaling, and interactions. They help cells recognize and bind to each other, promoting cell adhesion, migration, and organization within tissues. Additionally, attachment proteins can also mediate immune responses, regulate cell growth and differentiation, and contribute to the overall stability and function of cells in the body.

What does the protein structure of a virus have to do with the attachment to host cells?
The protein structure of a virus typically includes specific proteins on its outer surface that help it attach to receptors on host cells. This attachment is crucial for the virus to gain entry into the host cell, infect it, and replicate. The binding specificity between viral proteins and host cell receptors is a key determinant of the virus's ability to infect specific cell types.
What is most important for attachment of a virus to a host cell?
While we are constantly referring to bi-lateral specificity, as in the functions of Dna, here is a case where a virus offers out it's 'hand': it seems likely that it expects to reach for, find and attach to some outstretched Cell Membrane Component.
Neurotransmitters bind to specific proteins on the postsynaptic membrane called?
Neurotransmitters bind to specific proteins on the postsynaptic membrane called receptors. These receptors initiate a series of events that can either excite or inhibit the firing of the postsynaptic neuron.
What are membrane proteins that bind to signals by which cells communicate?
Receptors are membrane proteins that bind to signals by which cells communicate. These receptors recognize specific signaling molecules such as hormones, neurotransmitters, and growth factors, and initiate a cellular response upon binding. Examples include G-protein coupled receptors and receptor tyrosine kinases.
Why is the shape of proteins important for their function?
The shape of proteins is important for their function because it determines how they interact with other molecules. The specific three-dimensional structure of a protein allows it to bind to other molecules, such as enzymes or receptors, and carry out its specific biological functions. If a protein's shape is altered, it may not be able to perform its intended role effectively.
What property of a virus determines its attachment to a host cell membrane?
The specific viral proteins on the surface of the virus determine its attachment to host cell membrane receptors. These proteins bind to complementary host cell receptors, allowing the virus to attach and enter the host cell.

The membrane receptors are proteins that would be synthesized on ribosomes where?
The membrane receptors are proteins that are synthesized on ribosomes located in the cytoplasm of the cell. Once synthesized, these proteins are then transported to the cell membrane where they become embedded and function as receptors for specific signaling molecules.
Neurotransmitters bind to specific proteins on the postsynaptic membrane called?
Neurotransmitters bind to specific proteins on the postsynaptic membrane called receptors. These receptors initiate a series of events that can either excite or inhibit the firing of the postsynaptic neuron.

Neurotransmitters attach to what molecules in the cell membrane?
Neurotransmitters attach to specific proteins called receptors on the cell membrane. These receptors are typically ligand-gated ion channels or G protein-coupled receptors that initiate cellular responses when neurotransmitters bind to them.
Are antibodies and cell receptors similar?
Antibodies and cell receptors both play roles in detecting and responding to specific molecules. However, antibodies are proteins produced by the immune system to recognize and neutralize foreign invaders like pathogens, while cell receptors are proteins on cell surfaces that bind with specific signaling molecules to trigger cellular responses.
Why are viruses so specific in the cell the infect?
Viruses have specific proteins on them which only binds to certain receptors, which are present in certain cell's plasma membrane.
What determines whether a neurotransmitter will have an inhibitory excitatory effect?
How a neurotransmitter interacts with the receptors determines its effects. They activate receptors to perform specific functions in the body.the type of receptor
What part of the cell is stimulated by outside chemicals triggering the cell to carry out specific functions?
Cell surface receptors are stimulated by outside chemicals, such as hormones or neurotransmitters, which in turn trigger the cell to carry out specific functions. The binding of these chemicals to the receptors initiates a signaling cascade within the cell that leads to various cellular responses.
