In addition to their role as building blocks for proteins, amino acids are used as precursors for the biosynthesis of a wide variety of molecules. Match the amino acids with the molecules for which they act as precursors. Histamine Epinephrine Scrotonin Glutathione Heme NAD(H)tyrosine histidine eysteine glycine glutamate tryptophan

Amino acids are the building blocks or monomers of proteins. These are the molecules that act as the precursors for the biosynthesis of various hormones some other molecules of our body. these amino acid molecules for by the process of protein synthesis.

The given amino acids are precursors of the following molecules-

1. Histamine - Histidine

2. Epinephrine - Tyrosine

3. Serotonin - Tryptophan

4. Glutathione - Cysteine, Glutamate and Glycine

5. Heme - Glycine

6. NAD(H) - Tryptophan

1. (1.2kw)x(15/60hours) = .3kwh --> a

2. (5kw)x(90/60hours)x(8cents/kwh) = $0.60 --> d

3. microwave --> 1200 watts = (1.2kw)x(6/60hours) = .12kwh

coffee-maker --> 900 watts = (.9kw)x(10/60hours) = .15kwh

therefore, it requires more energy for the coffee-maker to do the same amount of work.

so the answer is a.

hope it mark me as brainlieast.
