What do you notice about the ligands and their receptors in these images?

Biology

aliina [53]3 years ago

Answer:

What can be noticed about the ligands and their receptor is that the configuration of both coincide, as a key would with its lock, which demonstrates the specificity of a receptor by its ligand.

Explanation:

A <u>ligand</u> corresponds to a molecule considered a signal or a messenger, while the <u>receptor</u> is a protein on the cell surface, with the capacity to accept a ligand.

Ligands and receptors constitute pairs that complement each other, so that <u>each receptor can bind to a specific ligand</u>, similar to what happens with a key and a lock.

Once the ligand-receptor complex is formed, changes occur inside the cell, which define a certain effect.

fungal and protist infections, especially those that are deeper than the skin, are especially hard to treat. why?​
matrenka [14]

Answer and explanation:

Fungi and protists are eukaryotic. However, antibiotics selectively targets prokaryotic cells. Thus, the use of antibiotics for the treatment of fungal and protist infection is of no use at the first place. Secondly, if we use the other medicines that could kill the fungi/protists (e.g. fungicides), they could also kill the host's cells (animal's cells). This become further difficult if the infection is deeper in the skin. This is because, we would not be able to apply the medicine as direct application on skin but would give either intravenous or via food. This would increase the chance of imacting negatively the other organs/cells. The only option in such scenario is the surgery, which cannot be 100% effective because some spores may left even after the treatment.
