What’s the rest of the question
Its more natural and doesn't have side effects
I think the correct answer from the choices listed above is the second option. The enzyme pepsin that is present in the stomach denature in the intestine due to the alkaline environment of the intestine. This is because pepsin has an optimum pH that is very low which is ideal for the acidic conditions of the stomach.
In the start of the light cycle, light-dependent reactions harness energy from the sun in order to create chemical bonds. These bonds are known as ATP and NADPH. These are the molecules that carry energy which are made in the stroma. The stroma is where the Calvin cycle takes place.
worms get their energy through the biological process of cellular respiration where glucose from the food they eat is converted into ATP. This molecule is packed with potential energy, and is used by the cells within the worm to do work.
Hope this helps (:
