Question

which of the following terms describes metabolic pathways that break down complex molecules to release stored energy?
catabolic pathways
anabolic pathways
bioenergetic pathways
endergonic pathways

Explanation:

• Catabolic pathways: These pathways break down complex molecules (such as glucose, proteins, and fats) into simpler ones. During this breakdown, stored energy (like the energy in the chemical bonds of these complex molecules) is released. For example, cellular respiration is a catabolic pathway where glucose is broken down to release energy in the form of ATP.
• Anabolic pathways: These are the opposite of catabolic pathways. They build complex molecules from simpler ones and require an input of energy. For instance, the synthesis of proteins from amino acids is an anabolic process.
• Bioenergetic pathways: This is a more general term that encompasses the study of energy flow in biological systems, including both catabolic and anabolic aspects related to energy transformation, but it is not specifically the term for pathways that break down molecules to release energy.
• Endergonic pathways: These are reactions or pathways that absorb energy from the surroundings. They are not related to the breakdown of molecules to release energy.

Answer:

catabolic pathways
