Plant Physiology: Photosynthesis and Respiration
In light reaction, plastoquinone facilitates the transfer of electrons from
$$NADPH_{2}$$ is also called as
The $$NADPH_2$$ is synthesized in non-cyclic photophosphorylation in the light phase of photosynthesis. This is used subsequently in the dark phase to reduce carbon dioxide into sugars. $$NADPH_2$$ is also called as reducing power. The substance provides the hydrogen molecules to perform reduction of the other substance.
Thus, the correct answer is option D.
In light reaction, plastoquinone facilitates the transfer of electrons from
Which of the following is incorrect about the light reactions of photosynthesis?
Energy released during movement of electrons through the photosystems in photosynthesis is used to drive protons across the membrane against concentration gradient. As a result the protons accumulate in
Which one is involved in Z-scheme of photosynthesis?
Select the correct option: The Z scheme of photophosphorylation follows the following sequence: PS II$$ \underset{A}{\rightarrow}e^{-}acceptor\underset{B}{\rightarrow} ETS \underset{B}{\rightarrow}PS \,I\underset{C}{\rightarrow}e^{-} acceptor\underset{D}{\rightarrow}NADP^{+}$$ Which of the following option for A, B, C and D transfer of electrons? A B C D
During the Z scheme, electrons excited absorption of light in PSI are transferred to the primary acceptors, and therefore must be replaced. The replacements come directly from
Read the following statement and select the correct ones. (i) PS I is involved in non-cyclic photophosphorylation only. (ii) PS II is involved in both cyclic and non-cyclic photophosphorylation. (iii) Stroma lamellae membranes possess PS I only, whereas grana lamellae membranes possess both PS I and PS II.
