Question

Does the synthesis of the macromolecule require or release energy?

Answer 1

Synthesis always requires energy. Breakdown of covalent bonds release energy.

Answer 2

Dehydration synthesis: is an anabolic process by which two molecules are chemically bonded through the use of enzymes, ATP, and a loss of water.

glucose + glucose + enzyme + ATP = maltose + water + enzyme.



ATP is the energy used to allow the reaction to run to completion.

Answer 3

It requires energy. It takes work to put things together which is what you are doing in macromolecule synthesis.
