Answer:
NAD is a coenzyme found in all cells. It consists of two nucleotides linked through their phosphate groups with a nucleotide that contains an adenosine ring and another that contains nicotinamide.
Explanation:
In metabolism, NAD participates in oxidation reduction reactions. This coenzyme is found in two forms in the cells: NAD and NADH. NAD accepts electrons from other molecules and is reduced, forming NADH, which you can use as a reducing agent to donate electrons. These electron transfer reactions are the main function of the NAD.
In living organisms, NAD can be synthesized from scratch from the amino acids tryptophan or aspartic acid. Some NADs are found in nicotinamide adenine dinucleotide phosphate (NADP), whose chemistry is similar to NAD, although it has different functions in metabolism.

Answer:
Cellular reactions are made spontaneous by C coupling with ATP breakdown to ADP.
Explanation:
ATP is an energy rich compound.ATP undergo hydrolysis to generate high amount of free energy.
The free energy of ATP hydrolysis is used to make a non spontaneous reaction or thermodynamically unfavorable reaction to thermodynamically favorable manner.
Thus the cellular reactions are made spontaneous by coupling with ATP breakdown to ADP.
Healthcare associated or nosocomial pneumonia are
acquired by non-hospitalized patients in hospitals or other health care
facilities. Pneumonia are poly-microbial in origin and the causative agents are
viruses, bacteria and fungi. In nosocomial pneumonia, bacteria enter the lower
respiratory tract due to mechanical ventilation. Meanwhile, persons in general
population experience community-acquired pneumonia.

Complete question
Reagan is a young girl with a genetic developmental disorder. Her language development has been severely affected by this condition, and as such she has been diagnosed with a specific language impairment. Which condition is NOT likely to have contributed to this delay?
A) autism spectrum disorder
B) Down syndrome
C) fragile-X syndrome
D) PKU
Solution
Phenylketonuria (PKU) is a kind of genetic disorder in which body starts producing and building up phenylalanine amino acid. PKU arises when the Phenylalanine hydroxylase enzyme is not synthesized due to a genetic defect thereby affecting creation of neurotransmitters such as epinephrine, norepinephrine, and dopamine. Some of the symptoms of this disorder are hyperactivity, seizures, eczema, tremors etc. PKU is not connected with language development issues and hence correct option is D
