False:Cellular respiration is a catabolic reaction because it breaks down glucose into carbon dioxide and water while releasing ATP. The breakdown of molecules to generate usable energy is characteristic of catabolic processes, not anabolic ones.

A. Nonkeratinized stratified squamous:This epithelium type is found in areas subject to friction and abrasion, such as the esophagus and oral cavity. Its multiple layers make it unsuitable for efficient gas exchange, as diffusion is slowed by the thickness of the tissue.

B. Simple columnar:Simple columnar epithelium is specialized for absorption and secretion, commonly found in the gastrointestinal tract. Its tall cell structure is not ideal for rapid diffusion, making it poorly suited for alveolar gas exchange.

C. Simple squamous:Simple squamous epithelium consists of a single, thin layer of flat cells. Its delicate structure provides a minimal barrier for diffusion, allowing oxygen and carbon dioxide to rapidly pass through the alveolar walls during respiration.

D. Simple cuboidal:Simple cuboidal epithelium is found in glands and kidney tubules where secretion and absorption occur. Its cube-shaped cells are thicker than squamous cells, creating a greater distance for gases to diffuse, which reduces efficiency in the lungs.
