Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
This type of pathway breaks large molecules down into smaller fragments, releases energy, and is spontaneous
A
Catabolic
B
Anabolic
C
Exergonic
D
Endergonic
Explanation: 

Detailed explanation-1: -Catabolic reactions give out energy. They are exergonic. In a catabolic reaction large molecules are broken down into smaller ones. For example, the reverse of the condensation reactions described above, i.e. hydrolysis reactions, are catabolic.

Detailed explanation-2: -Catabolic pathway: large molecules are broken down into small ones. Energy is typically released.

Detailed explanation-3: -Catabolism (pronounced: kuh-TAB-uh-liz-um), or destructive metabolism, is the process that produces the energy needed for all activity in the cells. Cells break down large molecules (mostly carbs and fats) to release energy.

Detailed explanation-4: -Anabolic pathway refers to the metabolic way where energy is required to form bonds. In this pathway, simple micro molecules combine to form larger and complex macromolecules. Example-photosynthesis, glycogenesis, etc. Anabolic pathways are always endergonic since energy is consumed to form bonds.

Detailed explanation-5: -Catabolic pathways break down molecules and produce energy. Because almost all metabolic reactions take place non-spontaneously, proteins called enzymes help facilitate those chemical reactions.
