|
|
|
are usually highly spontaneous chemical reactions
|
|
|
consume energy to build up polymers from monomers
|
|
|
release energy as they degrade polymers to monomers
|
|
|
consume energy to decrease the entropy of the organism and its environment
|
Detailed explanation-1: -They are used for digesting sugars. They consume energy to build up polymers from monomers. They release energy by breaking down polymers into monomers. They increase the entropy of the organism.
Detailed explanation-2: -A metabolic pathway is a series of chemical reactions in a cell that build and breakdown molecules for cellular processes. Anabolic pathways synthesize molecules and require energy. Catabolic pathways break down molecules and produce energy.
Detailed explanation-3: -Energy source Anabolism is powered by catabolism, where large molecules are broken down into smaller parts and then used up in cellular respiration. Many anabolic processes are powered by the cleavage of adenosine triphosphate (ATP).
