5. C. role in the food chain
Explanation:
Answer:
X is negative heterotropic modulator
Explanation:
In allosteric regulations, modulators are molecules that causes a change in the conformation of an enzyme, hence, resulting a change in enzyme activity. It can lead to a decrease or an increase of the enzyme. When a molecule decreases the enzyme activity it called a negative modulator, when it increases or activates the enzyme activity, it is called a positive modulator.
A positive or negative modulator can either be homotrophic (substrate acts as modulator) or heterotropic (another ligand acts as modulator).
In the example above, X is negative heterotropic modulator, because the modulator is different from the substrate and it also decreases the enzyme activity.
Most proteins in living organisms are composed of 40 amino acid residues in total, and nine of those are crucial for human health.
Which majority of amino acids make up proteins in living things?
- Only twenty different amino acids, each with a distinct side chain, make up proteins. Different chemistries can be found in the side chains of amino acids. The majority of amino acids contain side chains that are nonpolar.
- There are nine essential amino acids:
- tryptophan
- valine
- isoleucine
- leucine
- lysine
- methionine
- phenylalanine
- threonine
- methionine
What Constitutes Proteins?
- Amino acids are the basic units of proteins. They are tiny chemical compounds with an alpha (central) carbon coupled to an amino group, a carboxylic acid group, hydrogens, and a changeable element known as a side chain.
- A protein is made up of a lengthy chain of amino acids that are connected by peptide bonds. The biological process that links the carboxyl unit of one amino acid towards the amino group of a nearby amino acid results in the extraction of a water molecule, forming peptide bonds. The main structure of a protein is thought to be its linear amino acid sequence.
