The electrons that are accepted by NADP+ to form NADPH during the noncyclic pathways of the light-dependent reactions are emitted by ____.

A) photosystem I
B) hydrogen ions
C) glucose
D) sunlight
E) ATP synthase

Photosystem I

A complex found in the chloroplasts of plants, algae, and cyanobacteria that is involved in the light-dependent reactions of photosynthesis, capturing light energy to produce ATP and NADPH.

NADPH

Nicotinamide adenine dinucleotide phosphate, a coenzyme that plays a critical role in photosynthesis and fatty acid synthesis by carrying electrons.

Noncyclic Pathways

Metabolic pathways that do not recycle their starting molecule, leading to the production of end products.

  • Recognize the key molecules and enzymes involved in photosynthesis, including ATP, NADPH, rubisco, and chlorophyll.
  • Absorb information regarding the operation and significance of light-dependent reactions in photosynthesis.

Final Answer :
A
Explanation :
The electrons that are accepted by NADP+ to form NADPH during the noncyclic pathway of the light-dependent reaction are emitted by photosystem I (PSI). PSI absorbs light at a wavelength of 700 nm, which excites the electrons and transfers them down an electron transport chain. At the end of this chain, NADP+ accepts the electrons and combines them with H+ ions from the surrounding medium to form NADPH.
