Praxis 5511 Practice Question

Which tissue stores energy-rich molecules?

Correct Answer: D

Rationale: Energy-rich molecules are primarily stored in adipose tissue, which specializes in fat storage. Adipose cells, or adipocytes, efficiently accumulate lipids, providing energy reserves for the body.

Bone tissue, while essential for structural support, does not serve as a significant energy storage site. Muscle tissue uses energy for contraction and maintains some glycogen reserves, but it is not primarily an energy storage tissue. Epithelium, primarily involved in protection and absorption, does not function in energy storage. Thus, adipose tissue is uniquely suited for this role.
