STEP ONE: Harvesting Radiant Energy
The first step of photosynthesis occurs in the chloroplasts of plant cells. Light photons are absorbed by a pigment called chlorophyll, which is abundant in the thylakoid membrane of each chloroplast. Chlorophyll appears green to the eye because it does not absorb green waves on the light spectrum. It reflects them instead, so that’s the color you see.
STAGE 2: Converting Radiant Energy
After radiant energy from sunlight is absorbed, the plant converts light energy into a usable form of chemical energy to fuel the plant’s cells
STAGE 3: Storing Radiant Energy
The last stage of the photosynthesis process is known as the Calvin-Benson cycle, in which the plant uses atmospheric carbon dioxide and water from soil to convert ATP and NADPH. The chemical reactions that make up the Calvin-Benson cycle occur in the stroma of the chloroplast.

Answer:
The correct answer will be option C.
Explanation:
ATP is the energy molecule which on hydrolysis provide energy to the cells for metabolic functions.
In vitro, the standard free energy of the ATP is -30.5 kJ/mol but its value varies in the cell as the concentration of ATP and its products like ADP, AMP and Pi are unequal in a cell. The Mg2+ in the cytosol has the ability to bind ATP and ADP, as well as the time of ATP hydrolysis, differs from cell to cell, thus influencing the concentration of ATP and its products.
Thus, option C is the correct answer.
I believe its D they decompose wood and other tough materials and then absorb them.
Pulmonary surfactant is a mixture of lipids and proteins which is secreted into the alveolar space by epithelial type II cells. The main function of the surfactant is to lower the surface tension at the ir/liquid interface within the alveoli of the lung. In babies born prematurely, pulmonary surfactant may not be present in adequate amounts due to insufficient exocytosis in type II alveolar cells.
