Respuesta :
In our metabolic system, we have that there are anabolic reactions (reactions that absorb energy/create molecules) and catabolic reactions (reactions that release energy usually, break down molecules). We have that the first 2 reactions are clearly catabolic and of the most important ones in our organism. The 3rd is catabolic too since we have a breakdown; the 4th is the correct choice since new, bigger molecules are created (and this also needs energy).
Correct answer choice is:
D. Glycerol and fatty acids using energy to make lipids.
Explanation:
Anabolism is powered by catabolism, where extended molecules are split down into tinier particles and then applied up in cellular respiration. Several anabolic methods are powered by the hydrolysis of adenosine triphosphate (ATP). Anabolic methods direct proceeding "building up" glands and tissues.
Fats are a group of lipids comprising two varieties of monomers, fatty acids, and glycerol. Glycerol is a three carbon biomolecule comprising three hydroxyl combinations, one bonded to every carbon atom. Dehydration synthesis produces an ester linkage within the carboxyl group of fatty acids and a hydroxyl assembly in glycerol.
