Individuals without AFS have a glutamic acid at position 487 on the ALDH2 protein, whereas individuals with AFS have a lysine at
azamat

Answer:

Aldehyde Dehydrogenase 2 (ALDH2) is an enzyme required to eliminate toxins such as acetaldehyde and alcohol, thereby mutations in this protein may be associated with the Alcohol flush syndrome (AFS)

Explanation:

ALDH2 is a protein required for ATP generation by catalyzing the oxidation of aldehydes to carboxylic acids (i.e., oxidation of NADH to NAD+). Mutations in the ALDH2 gene have been associated with the inactive form of this enzyme, and this specific mutation at position 487 alters its enzymatic activity associated with the metabolism of acetaldehyde and alcohol. This amino acid substitution may lead to the active site-directed inactivation of the enzyme.

Which of the following statements is accurate?
PIT_PIT [208]

C. Useful energy out of a system is always less than the energy input of that system.

Explanation:

The correct statement of the given options is that useful energy out of a system is always less than the energy input of that system.

This is in compliance with the third law of thermodynamics which states that "energy transformation in a system is not 100% efficient".

  • At every stage energy is usually lost when it is transformed from one form to another.
  • There is no machine that is 100% efficient.
  • A machine that is 100% efficient will convert all the useful energy in it to do work and even more.
  • In system energy is usually lost as a result of heat and to overcome friction.
  • This reduces the amount of energy out of a system.
