Answer:
Choosing light dependent phase of the photosynthesis process.
Explanation:
When the sunlight falls on the leaves of the plant, Light is absorbed by the leaves. The photosystem II captures or traps the photons of the light that leads to electrons of a chlorophyll in excited state with a very large energy charge.
Primary electron acceptor traps the excited electron and simultaneously electrons captured from the water as well. Electrons then move to the PSI (photosystem I) through cytochrome b6f. At the photosystem I these electrons result in the energy imbalance, the electrons that are captured by electron acceptor again that move it to ferredoxin that take them for the production of ATP to ATP synthase.

Answer:
(1) glycerophospholipids ⟶ (C) lipids with phosphate-containing head groups
(2) cerebrosides ⟶ (D) fatty acid linked through an amide bond to the sphingosine C(2)-amine
(3) gangliosides ⟶ (B) anionic sphingolipids containing one or more sialic acid residues
(4) sphingolipids ⟶ (A) built on sphingosine
Explanation:
1) Choline (Fig. 1) is a glycerophospholipid. It is a glycerol-based lipid with a phosphate-containing head group.
(2) Galactosylceramide (Fig. 2) is a cerebroside. It contains a fatty acid linked through an amide bond to the sphingosine C(2)-amine
(3) Gangliosides are glycosphingolipids that contain sialic acid. GQ1b (Fig. 3) is one of the most abundant gangliosides in the human brain. The carboxyl group of the sialic acid is in the ionic form.
(4) Sphingomyelin (Fig. 4) is a sphingolipid. It is based on sphingosine, with a phosphocholine head and a fatty acid chain.
