Which one of the following statements about photophosphorylation is false?

Biology
1 answer:
Zepler [3.9K]3 years ago
5 0

Answer:

C)The luminal side of the thylakoid membrane has a higher pH than the stromal side.

Explanation:

During the photophosphorylation, the electrons move through many electron carriers which allow the transport of hydrogen ions in the luminal side against the concentration gradient. This allows the increase in the Hydrogen ion concentration to the luminal side of thylakoid membrane and reduction in the hydrogen ion concentration of the stromal side.

Therefore due to the increased concentration of H⁺ ions in lumen during the photophosphorylation, the lumen has a lower pH than the stroma. During photophosphorylation, the pH of lumen decreases up to 4 and the pH of stroma increases up to 8. So the false option is C.

This crack shown in the lithosphere was created by the movement of two or more tectonic plates. What is this crack called?
pav-90 [236]

Answer:

Fault

Explanation:

A break or crack in earth's lithosphere along with rocks move. Earth is made up of 4 basic layers a crust,mantle,outer core,inner core and lithosphere.  A solid crust and hard layers of mantle  make up a region name the lithosphere. The lithosphere is made up of pieces of tectonic plates. These plates are constantly changing and move towards the mantle. Non-stop movement of tectonic plates causes stress on the earth's outermost layer i.e,the crust. When these stresses extends it leads to cause cracks called faults.
