The greater omentum is composed of which membrane?

A. The type I cells secrete surfactant and the type II cells will give rise to bronchiolar smooth muscle cells: type I cells do not secrete surfactant, and type II cells do not give rise to bronchiolar smooth muscle.
B. The type I cells form alveolar walls and the type II cells secrete surfactant: type I pneumocytes are thin squamous cells forming most of the alveolar surface for gas exchange; type II pneumocytes secrete surfactant and can proliferate/differentiate into type I cells.
C. Both type I and type II cells produce surfactant: only type II pneumocytes produce surfactant; type I do not.
D. The type I cells produce cartilage for larger airways and the type II cells give rise to the ciliated cells lining the trachea: neither pneumocyte type produces cartilage or airway ciliated cells; those are separate tissues/cell lineages.

A. Pepsin or trypsin and peptidases: these are protein digesting enzymes, not primary fat digesters.
B. Amylase and disaccharidases: these digest carbohydrates, not fats.
C. Lipase: lipase (plus bile for emulsification) is required to chemically digest fats into fatty acids and glycerol.
D. Amylase and pepsin: amylase digests starch and pepsin digests proteins; neither is the principal fat-digesting enzyme.
