Based on the information provided about the model and the context of constructing biomolecules, we can evaluate the accuracy of the statements regarding the formation of the new biomolecule:
A. Proteins are being formed. - True if the biomolecule is a protein formed from amino acids.
B. The monomers are amino acids. - True if the biomolecule being formed is indeed a protein, as proteins are made from amino acids.
C. This is a hydrolysis reaction. - False. Hydrolysis refers to the breaking down of polymers into monomers with the addition of water, which is the opposite of what is described.
D. Carbohydrates are being broken down. - False. If we are forming proteins from amino acids, carbohydrates are not being broken down in this context.
E. This is a dehydration synthesis reaction. - True. Dehydration synthesis (or condensation) is the process by which monomers are combined to form a polymer, releasing water.
Therefore, the accurate statements describing the formation of the new biomolecule are: A, B, and E.
