summary

1. complete this table to summarize catabolic and anabolic pathways.

metabolic pathway\tanabolic\tcatabolic
definition
releases or absorbs energy?
δg <0 or >0
spontaneous or not?
exergonic or endergonic?
reactants or products have higher energy?
catalyzed by enzymes?
example

Explanation:

Anabolic pathways build complex molecules from simpler ones, absorbing energy (endergonic), with $\Delta G> 0$, non - spontaneous, and products have higher energy. They are catalyzed by enzymes, e.g., protein synthesis. Catabolic pathways break down complex molecules into simpler ones, releasing energy (exergonic), with $\Delta G < 0$, spontaneous, and reactants have higher energy. They are also catalyzed by enzymes, e.g., cellular respiration.

SPONTANEOUS OR NOT?	Not spontaneous	Spontaneous
EXERGONIC OR ENDERGONIC?	Endergonic	Exergonic
REACTANTS OR PRODUCTS HAVE HIGHER ENERGY?	Products	Reactants
CATALYZED BY ENZYMES?	Yes	Yes
EXAMPLE	Protein synthesis	Cellular respiration
