As a result of its involvement in a reaction, an enzyme _____.
goldfiish [28.3K]

As a result of its involvement in a reaction, an enzyme is unchanged.

Enzymes are catalysts that speed up chemical reactions that occur within the biological systems (they increase the reaction rate by lowering its activation energy). Enzymes react with substrate that binds to them (key-lock mechanism) and convert the substrate into the product. Most of enzymes are proteins by their structure but a few are catalytic RNA molecules-ribosymes.

Enzyme activity can be affected by other molecules (activators and repressors), pH, temperature etc.

Most amines are ________, meaning they dissolve in water and therefore cannot cross the cell membrane. The ________ hormones are
Doss [256]

Answer: 1. Lipophobic

              2.Thyroid

              3.lipophilic

Explanation:

 Chemical messengers can be classified by their chemical characteristics including their solubility in water and their chemical structure.  

Depending on their solubility in water they can be classified in two groups:

  • Hydrophobic (lipophilic) - Molecules are lipid soluble and can easily cross the plasma membrane.

  • Hydrophilic (lipophobic) - Molecules that are water soluble and do not readily cross the plasma membrane.

Depending on the chemical structure  

Amino Acids are lipophobic.

Amines are derived from amino acids and contain an amine group (-NH2, known as the amino group). An important group of these are the catecholamines which contain a 6 carbon ring (catechol) and are derived from tyrosine. These include dopamine, norepinephrine and epinephrine. The thyroid hormone is derived from tyrosine.  All except thyroid hormones are hydrophilic. The thyroid hormone is lipophilic (hidrophobic)
