Which of the following is TRUE in terms of metabolism?
A)Organisms can be classified as either catabolic or anabolic,but not both.
B)The reversible reaction ADP + Pi = ATP is linked with other reactions in many metabolic pathways.
C)Metabolic reactions first appeared in evolutionary history with the appearance of eukaryotes.
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 fundamental component of many metabolic pathways and is involved in both anabolic and catabolic reactions. Organisms can also have both catabolic and anabolic pathways operating simultaneously. Metabolic reactions are thought to have existed in early prokaryotes and were refined in later eukaryotes. Oxidation-reduction reactions occur in all domains of life.
