What kind of antigens are small simple molecules?
Small simple molecules that can act as antigens are referred to as haptens. Haptens are typically not immunogenic by themselves but can elicit an immune response when they bind to larger carrier proteins or molecules, forming a complex that the immune system can recognize. Examples include drugs like penicillin, which can trigger allergic reactions when they bind to proteins in the body.
What type of protein is used to carry other molecules?
Carrier proteins are types of proteins used to carry other molecules, such as ions or small molecules, across cell membranes. These proteins can bind to specific molecules and transport them from one side of the membrane to the other. Examples include ion channels and transporters.
How facilitated diffusion is achiveved for small polar molecules and ions?
Facilitated diffusion for small polar molecules and ions is achieved through specific transmembrane proteins, such as channel proteins and carrier proteins. Channel proteins create hydrophilic pathways that allow ions and small polar molecules to passively flow across the membrane down their concentration gradient. Carrier proteins bind to the molecules, undergo conformational changes, and transport them across the membrane without the need for energy. This process allows cells to regulate the entry and exit of essential substances efficiently.
Proteins that attach molecules in order to deliver them to another site?
These proteins are likely transport proteins, such as carrier proteins or channel proteins, which bind to specific molecules and facilitate their movement across cell membranes or through the bloodstream. These proteins help to transport essential molecules like hormones, ions, and nutrients to their target destinations in the body.
How is mRNA silenced?
mRNA can be silenced through a process called RNA interference (RNAi). In RNAi, small RNA molecules called small interfering RNAs (siRNAs) or microRNAs (miRNAs) bind to the mRNA molecules and prevent them from being translated into proteins. This silencing can occur through mechanisms such as degradation of the mRNA or inhibition of its translation. Additionally, other factors such as RNA-binding proteins and long non-coding RNAs can also contribute to mRNA silencing.
Small molecules that bind with self-proteins to produce antigenic substances are called?
Small molecules that bind with self-proteins to produce antigenic substances are called happens. The unique area that a lymphocyte recognizes and binds to an antigenic determinant.
What are small molecules that must combine with large proteins to become immunogenic?
Small molecules that must combine with large proteins to become immunogenic are called haptens. Haptens alone are not immunogenic, but when they bind to proteins in the body, they can elicit an immune response.
What do signal molecules bind to in cells?
Receptor Proteins

What membrane surface molecules bind to proteins and serve as molecules identification tags?
Carbohydrates

What is effector?
An effector is a molecule or protein that can bind to a specific site on an enzyme, receptor, or other protein to regulate its activity. Effectors can activate or inhibit the function of the protein they bind to, ultimately influencing cellular processes.

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 small molecules bind to hemoglobin?
Carbon dioxide and BPG bind to amino acids located on hemoglobin. Oxygen molecules bind to the iron molecules located in the heme. Each hemoglobin molecule can carry up to four oxygen molecules, one on each of the four iron molecules. Nitric oxide can also bind to hemoglobin when either oxygen or carbon dioxide are bound to the hemoglobin.
What binds to aluminum?
There are a number of things that will bind to aluminum. These include poly filters, EDTA, as well as oxygen.
