Question

Chemical reactions in a living system function to

A) only transfer energy from one molecule to another.
B) create new energy.
C) only use energy stored in a molecule.
D) transfer energy from one molecule to another or use energy stored in a molecule.

Answer 1

Chemical reactions in a living system function to transfer energy from one molecule to another or use energy stored in a molecule.

Step-by-step explanation:

Chemical reactions in a living system function to transfer energy from one molecule to another or use energy stored in a molecule. Living organisms obtain energy from their surroundings and transform it into usable energy to perform various cellular processes. An example of this is the transformation of chemical energy stored in organic molecules such as sugars and fats into energy within molecules of ATP (Adenosine triphosphate), which is easily accessible for cellular work.
