Answer:
a. the pH within the thylakoid is less than that of the stroma
Explanation:
The pH of thylakoid membrane is 8 at normal conditions but it became highly acidic like 4 during photosynthesis. The electron transport chain utilize the energy released by excited electrons to pump the H+ ions to lumen of thylakoid membrane from stroma during light reaction of photosynthesis. The H+ ions are present in both the stroma and thylakoid membranes. These high potential H+ ions are utilized by ATP synthase complex for the production of ATP.
We know that more the H+ ions lesser will be the pH and lumen have the high concentration of H+ ions. While the pH of stroma is normally kept acidic by plants to create a concentration and potential difference of H+ ions for the production of ATP. That why the lumen have lower pH than stroma of chloroplast.
Answer:
The answer is A I believe
Explanation:
Answer:
In the initial stages of digestion of food, the stomach performs an essential role. Apart from doing churning and squeezing the food bolus, it also discharges an amalgamation of compounds, together called gastric juice. It comprises mucus, water, pepsin, HCl, and intrinsic factor. Of these five constituents, the principal enzyme that takes part in the digestion of protein is pepsin.
It dissociates proteins into amino acids and smaller peptides, which can easily get captivated within the small intestine. This pepsin is released in its sedentary form, or zymogen form called pepsinogen by the chief cells present within the gastric lining. It is released in its sedentary form by the stomach, by this the stomach inhibits the auto-digestion of defensive proteins in the digestive tract's lining.
