Which of the following is true in terms of metabolism?
A) Organisms can be classified as either catabolic or anabolic, but not both.
B) Metabolic reactions first appeared in evolutionary history with the appearance of eukaryotes.
C) The reversible reaction ADP + Pi = ATP is linked with other reactions in many metabolic pathways.
D) Oxidation- reduction reactions occur in eukaryotes, but not in bacteria, nor in archaeans.

Question

Quizplus · Accepted Answer

The reversible reaction ADP + Pi = ATP is a key reaction in energy metabolism and is linked with many other reactions in metabolic pathways, such as glycolysis and oxidative phosphorylation.

Note: None of the other choices are true. Organisms can have both catabolic and anabolic pathways, metabolic reactions existed long before eukaryotes, and oxidation-reduction reactions occur in all domains of life (including bacteria and archaea).
