Item SB063001: Animals build their body structures by digesting proteins in their food to amino acids and using the amino acids to build their body proteins.
A word equation can be used to represent chemical reactions. The substances on the left side of the arrows are the starting substances, and the substances on the right side are the ending substances. The arrow represents “react to form.”
The word equations in the answer choices represent a sequence of two chemical reactions. Which sequence describes the sequence of reactions animals use to build body structures?
- 1) Proteins + Water → Carbohydrates
2) Carbohydrates → Proteins + Water - 1) Proteins + Water → Glucose
2) Glucose + Oxygen → Carbohydrates + Water - 1) Proteins + Water → Amino Acids
2) Amino acids → Proteins + Water - 1) Proteins + Water → Amino Acids
2) Amino Acids + Oxygen → Carbon Dioxide + Water
