Answer:
A proton gradient is generated by the transport of protons into the thylakoid lumen.
Protons move from the thylakoid lumen to the stroma through ATP synthase, producing ATP.
Explanation:
During photosynthesis, the environment is made acidic inside the lumen i.e. H⁺ are pumped into thylakoid lumen from stroma as a result of which more H⁺ are present in the thylakoid lumen as compared to stroma. It happens during light dependent reaction of photosynthesis. The concentration of H⁺ is already higher in lumen and transfer of more and more H⁺ from stroma increases the concentration of H⁺ even more leading to generation of a potential gradient. These H⁺ subsequently tend to move freely from lumen to stroma via "reverse pumps known as ATP synthase". The reason why these are known as reverse pumps is because pumps usually move particles from lower to higher concentration which is an active movement i.e. not natural so such movement requires energy. Naturally particles move from higher to lower concentration gradient until the concentration becomes equal on both the sides but pumps act opposite of this natural process and move particles from lower to higher concentration and utilize energy to do it. But here H⁺ are moving from higher to lower concentration which occurs naturally so ATP synthase rather than using energy tend to generate energy and this free energy is used to generate ATP from ADP & Pi (inorganic phosphate).
Answer:
B: The shorter and more rounded the Appalachian Mountains are more than four times older than the taller and more jagged Rocky Mountains
Explanation:
- The Appalachian mountains form a system of mountains in eastern North America and are older than rocky mountains as they were formed 480 million years ago and are similar to those of the alps. They form a barrier to the east to the west.
- They extend to southeast Canada and form zones of 300 miles wide. They form the mountain ranges surrounding hills and the dissected plateaus forming at an elevation of 6,684 meters from the sea level. <u>Whereas the rocky mountains are younger and have an elevation of 4,401 meters.</u>
