Answer: Put the answer in your own words.

The defining characteristic of prokaryotes is that they lack a membrane-enclosed nucleus. The single chromosome, usually circular, is tightly wound and compact. The region of the cytoplasm containing the chromosome is called the nucleoid.

IRISSAK [1]

Answer: B) energy released from exergonic reactions.  

Explanation:

Cell metabolism is the set of reactions that occur in the cellular environment to synthesize or degrade biomolecules to produce energy. Synthesis metabolism of biomolecules is known as anabolic (anabolism) and catabolic degradation (catabolism).

Endergonic reaction (product has more energy than reagents) and requires energy to occur. Anabolism occurs when the cell has sufficient energy or substrate. Catabolism, in turn, occurs in situations in which the body needs energy, such as between meals and fasting.

The reactions of anabolism and catabolism are opposite but occur in an articulated manner, allowing the maximization of available energy. Thus, while catabolism occurs spontaneously, an exergonic reaction with ATP production, anabolism is non-spontaneous, or endergonic, requiring energy to occur. In other words energy that drives endergonic reactions is often obtained from B) energy released from exergonic reactions.
