krek1111 [17]

Answer: Adrenal gland

Explanation: It is an automatic response known as the 'Fight or Flight response, that is stimulated by our adrenal gland that is in our endocrine system produces adrealine.

These glands are located above the kidneys, and they secrete adrelaine when a person is angry or afraid. As in this situation, you see that the person is most likely to be afraid.

Adrelaine causes increase in heartbeat and blood pressure, and produces other substances for instant energy. This is when the situation, as mentioned before, 'Flight or fight situation' comes in hand, which is, it prepares the person to run away, or to fight from a dangerous situation.

The pH of the inner thylakoid space has been measured, as have the pH of the stroma and of the cytosol of a particular plant cel
yawa3891 [41]

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.
