What purpose does the peptide bond serve in protein synthesis?

it connects amino acids.
it adds a water molecule to the amino acid chain.
it releases the protein from the trna.
it makes a strand of mrna.

The correct answer is- It connects amino acids.

Peptide bond is formed between two amino acids during protein synthesis. It is a bond between amino group (-NH2) of one amino acid and the carboxylic group (-COOH) of another amino acid, releasing a molecule of water.

Thus, during protein synthesis, peptide bond serves the purpose of connecting or linking amino acids together.

4.) metal

"-the movement of carbon from the nonliving environment into living things and back to the environment

-carbon is the essential component of proteins, fats, and carbohydrates (which make up all organisms)

-carbon exists in air, water, and living organisms

-producers convert carbon dioxide in the atmosphere into carbohydrates during photosynthesis

-bacteria in the atmosphere cycles through the system in filtration units

-in cellular respiration, carbon is released back into the atmosphere as carbon dioxide

-some carbon is stored in limestone (forming one of the largest "carbon sinks" on earth)

-largest carbon reservoir on earth= limestone

-carbon stored in the bodies of organisms as fat, oils, or other molecules may be released into the soil or air when the organism dies

-this may form deposits of coal, oil, or natural gas (fossil fuels, which increased the atmospheric carbon dioxide)

-fossil fuels store carbon left over from bodies of organisms that died millions of years ago

-they are located in the surface of earth, deep within the earth and beneath the ocean floor."
