Which statement correctly describes adipocyte hypertrophy and hyperplasia in fat storage?

Adipocytes can enlarge (hypertrophy) to store more triglyceride and new adipocytes can form (hyperplasia), enabling large increases in total fat storage.

Hyperplasia refers to shrinkage of adipocytes while hypertrophy describes formation of new adipocytes from bone marrow cells which is unrelated to fat storage.

Adipocytes store glycogen primarily, and their capacity is more limited than liver because they cannot expand in size to accommodate extra carbohydrate-derived energy.

Adipocytes only shrink and cannot increase in number or size after adolescence, so body fat always remains limited and strictly regulated by carbohydrate intake.
