Answer:
1.) Nucleic acid is an important class of macromolecules found in all cells and viruses.
2.) Two examples of nucleic acids include deoxyribonucleic acid (better known as DNA) and ribonucleic acid (better known as RNA). These molecules are composed of long strands of nucleotides held together by covalent bonds.
3.) Amino acids are the monomers that make up proteins.
4.) Phosphorus, Selenium, Iron, Zinc, Copper, Manganese, and Potassium.
5.) Protein helps repair and build your body's tissues, allows metabolic reactions to take place and coordinates bodily functions.
6.) Actin, tubulin, keratin.
You're welcome. Took a while, but worth it--
A catalyst increases the rate of reaction by decreasing the activation
energy. The correct answer is D. Catalysts are those substances that are
used in reactions to speed up the process. An example of a catalyst
might be iron, during the manufacture of ammonia within the Haber
process.
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.
