Agonists activate the receptor thereby <u>increasing</u> activity at the synapse while antagonists generally prevent agonists from activating the receptors thereby <u>decreasing</u> activity at the synapse.
- An agonist is the component that has the ability to increase the activity carried out by another substance.
- The agonists work from their faculty of coupling to a cell-type receptor, in this way, they manage to generate a certain action in the cell.
- The antagonists are the compounds that cause the opposite when they bind to the receptor, they cause a blockade by decreasing the activation of a synaptic receptor.
Therefore, we can conclude that agonists are compounds capable of increasing the action of synapse and blockers (antagonists) decrease activity at the synapse.

Answer:
In prokaryotes, the circular chromosome is contained in the cytoplasm in an area called the nucleoid. In contrast, in eukaryotes, all of the cell's chromosomes are stored inside a structure called the nucleus. Each eukaryotic chromosome is composed of DNA coiled and condensed around nuclear proteins called histones.
Explanation:
Options for the question have not been provided. They are as follows:
A. collagen fibers.
B. gelatinous mass.
C. actin and myosin fibers.
D. keratin fibers.
E. fibroblast cells.
Answer:
C. actin and myosin fibers.
Explanation:
Muscle cells or myocytes are unique because they have an abundant amount of actin and myosin fibers. These fibers are responsible for the contraction and relaxation of muscles. They are protein filaments, myosin is called thick filament and actin is called thin filament. Muscle cells not only have an abundant number of these fibers, but also they are organized properly in a fixed pattern. Each myosin is surrounded by actin and each actin is surrounded by myosin. They slide over each other in a fixed pattern to cause muscle contraction.
<span>Lipids doesn't have monomers while carbohydrates does and can be categorised into three: monosaccharide, disaccharide, polysaccharide.
For a polymer to be considered a polymer it must be comprised of monomers like proteins and other macromolecules.
There
are 20 different type of monomers present in proteins. Amino acids are
in reality the monomers of proteins. Out of the 20 amino acids, only 9
are considered essential. The other 11 are of little use to the humans.
The nine of the essential amino acids required by humans are Tryptophan,
lysine, Histidine, Isoleucine, Valine, Threonine, Phenylalanine,
Methionine and Leucine. The amino acids combine with one another to form
different types of proteins. These proteins satisfy a number of our
physical functional needs.<span> </span></span>
