The light dependent reaction produces B NADPH and ATP which are used in the light independent reaction or dark reaction.
Explanation:
Light dependent reaction also called light reaction occur in the thylakoid of grana. Light dependent reaction leads to the generate ATP and NADPH.
Role of ATP
ATP is an energy rich compound which undergo hydrolysis to generate huge amount of free energy. ATP is formed in the cyclic photo phosphorylation by the transport of electron through various electron carrier leading to generate energy for the phosphorylation of ADP into ATP.
Role of NADPH
NADPH act as reducing agent which is formed as the end product of noncyclic photo phosphorylation.NADPH helps in the reduction of Phosphoglyceric acid(PGA) into Phosphoglyceraldehyde(PGALD). The so formed PGALD undergo further reacts to generate glucose and also to regenerate Ribulose bisphosphate(RUBP).
Answer:
Option (3)
Explanation:
The continental crust is usually thick because it has an average thickness of about 35-40 km. In the high mountain ranges, it is the thickest, forming about 80 km on an average. These are formed when two continental plates form a sandwich pattern by sharing a convergent type of plate boundary.
For example, the thickest part of the crust is the Mt. Everest which lies in the great Himalayan range, which has started to form about 50 million years back. It is geologically the most recent mountain range.
The older mountains are continuously eroded in the geological past, as a result of which the height of the mountains is affected.
Thus, the correct answer is option (3).
