Which of the two enzymes are active in the stomach

Pepsinogen and gastric lipase

Explanation:

The protein digesting enzyme pepsin is activated by exposure to hydrochloric acid inside the stomach. Chief cells, also found within the gastric pits of the stomach.

the transfer of energy between two molecules spaced just nanometers apart plays a key role in many technologies, including photovoltaics, quantum information systems, lighting, and sensors, as well as in biophysics to measure nanometer distances and in photosynthesis. but an open question in this area is what effect, if any, the surrounding photonic environment has on this nanoscale energy transfer. by designing and performing a carefully controlled experiment to answer this question, scientists have settled the debate and found clues to improving the efficiency of many of the technologies that rely on this process.
