Question

Whereas chemoheterotrophs oxidize organic compounds to derive the high-energy electrons that enter the electron transport chain (ETC), many photoautotrophs strip electrons from . These electrons arc then excited by light and delivered to the electron transport chain. CO, H2O ATP O2 The following series of reactions depicts the biosynthesis of the amino acids methionine and threonine from oxaloacetate. Which statements are TRUE? [*Please mark all that apply.] This pathway is anabolic. This pathway is catabolic. This pathway is oxidative. The enzyme that catalyzes the conversion of oxaloacetate to aspartate is very possibly feedback inhibited by methionine or threonine.

Explanation / Answer

1. CO2 2. This pathway is catabolic
