Question

Carbohydrates and proteins are built up from their basic building blocks by the ________.

A) removal of a water molecule between each two units
B) removal of a nitrogen atom between each two units
C) addition of a water molecule between each two units
D) addition of a carbon atom between each two units

Answer 1

removal of a water molecule between each two units

Answer 2

Carbohydrates and proteins are built up from their basic building blocks by the addition of a water molecule between each two units. This process is known as dehydration synthesis or condensation reaction.

Step-by-step explanation:

Carbohydrates and proteins are built up from their basic building blocks through the addition of a water molecule between each two units. This process is known as dehydration synthesis or condensation reaction. In dehydration synthesis, two monomers join together with the removal of a water molecule, forming a covalent bond. This occurs in the formation of dipeptides in proteins and glycosidic bonds in carbohydrates.
