Which Statement About Metabolic Pathways is False

Question

Which statement about metabolic pathways is false?
A) The product of one reaction becomes the reactant for the next reaction.
B) They are a series of enzyme-catalyzed reactions.
C) Almost all are endergonic.
D) They are similar in all organisms.
E) Many are compartmentalized in eukaryotes.

Accepted Answer

Many metabolic pathways are exergonic, meaning they release energy. Some common examples include the breakdown of glucose during cellular respiration and the breakdown of fats during lipid metabolism. However, there are also endergonic pathways that require energy input, such as the synthesis of proteins or the synthesis of glucose during photosynthesis.
