If the RNA is double stranded, a protein called Dicer cleaves the dsRNA to form siRNA (3), small RNA of lenght around 23 nucleotides. Then, the two strands of the siRNA are separated (1). Afterwards, one strand forms the RNA complex that is called RISC (2). The final step is (4); the complex attaches to a duplicate of the strand that was discarded and destroys it

Hydrogen ions are important in the light-dependent reactions of photosynthesis because they produce a

Mnenie [13.5K]

Answer:

<u>a. the production of ATP</u>

<u />

Explanation:

Photosynthesis is type of biosynthesis that produces glucose from the reactants sunlight, carbon dioxide and water. It happens in two phases of the chloroplast, the light-dependent and light-independent reactions. In a light reaction that stimulates photosystems, pigments such as chlorophyll absorb light energy at specific wavelengths. Here,

Light energy stimulates photosystem complexes formed from chlorophyll. Photosystem II then absorbs and transfers light to a reaction core.
Water undergoes hydrolysis or splitting to yield an electron, a proton (H+) and oxygen.
energy is passed along the electron transport chain, where it forms builds up H+ and an electrochemical gradient in the thylakoid space
These protons pass through the ATPase enzyme embedded within the membrane, into the stroma, generating ATP from ADP.
NADPH is generated from NADP+
