B. gastric and lingual lipase function best in a low pH

C. all lipases begin digesting lipids in the location that they are secreted

D. pancreatic lipase is secreted by the same cell type that secretes pepsinogen

Answer 1

Ans:-

B,

Gastric and lingual lipase enzymes function best in a low pH , this statement is true about enzymes that can digest lipids.

Rest of the given options are wrong because:-

- All lipases are not secreted as zymogens because except amylase and lipase all enzymes are secreted as zymogens.

- All lipases does not begin digesting lipids in the location that they are secreted.

- Pancreatic lipase is not secreted by the same cell type that secretes pepsinogen because pancreatic lipase is secreted by the pancreas and pepsinogen is secreted by chief cells and mucous cells of the stomach .
