Question

Select the correct ones from the following.
A. Electrons are emitted from the light absorbed chlorophyll molecules.
B. Excited and expelled electrons undergo movement and result in the synthesis of ATP and the formation of NADPH ${}^{+}$ H ${}^{+}$.
C. Blue and red regions of the solar spectrum are responsible for photosynthetic dark reactions.
D. Greenlight spectrum plays a major role in light reaction of photosynthesis.

• A. A and B
• B. A and C
• C. B and D
• D. A and D

Answer 1

The correct option is A A and B

The molecules of chlorophyll present inside the chloroplast absorb solar energy. this is then released in the form of photons from them. The energy in the form of ATP and NADPH+, H+ molecule is released as a result of various movements by electrons. These high energy electrons are then transported to the electron transport chain (ETC) through different membrane carriers. Thus solar energy absorbed by chloroplasts is converted into chemical potential energy.

The dark reaction of photosynthesis, as the name suggests, is a light-independent reaction taking place in the stroma of the chloroplast

Red, orange, blue and violet are maximum absorbed light wavelengths during the process of photosynthesis.

So, option A and B are the correct answers.
