Answer:
Chlorophyll
Explanation:
Most plants contain a special colored chemical or pigment called chlorophyll that is used in photosynthesis. Chlorophyll is what absorbs the sun's energy and turns it into chemical energy.

Answer:
Substrate-level phosphorylation, which is a process of forming ATP by the physical addition of a phosphate group to ADP can take place in the cytoplasm during glycolysis or inside the mitochondrial matrix during the Krebs cycle.
Explanation:
Substrate-level phosphorylation is a metabolic reaction that results in the formation of ATP or GTP by the direct transfer of a phosphoryl (PO3) group to ADP or GDP from another phosphorylated compound.
Pigment molecules capturing photons in the chloroplast are organized in distinct structures called photosystems.
Photosynthetic pigments, which include chlorophyll a, chlorophyll b, and carotenoids, are light-harvesting molecules found in chloroplast thylakoid membranes. As previously stated, pigments and proteins are organized into complexes known as photosystems.
Photosystems are functional units for photosynthesis that are defined by specific pigment organization and association patterns. Their work is the absorption and transfer of light energy, which implies electron transfer. Photosystems are physically found in thylakoid membranes.
Chloroplasts are chlorophyll-containing organelles found in plant cells; they are essential for life on Earth because photosynthesis occurs in chloroplasts. Proplastids give rise to chloroplasts, as do chromoplasts, leucoplasts, and other plastids. Light energy absorption and conversion into biological energy

The decline in bone breakdown and increased mineralization causes blood calcium to decrease <span>back to normal levels. This happens when there is secretion of calcitonin. This circulation calcitonin is inhibiting </span>osteoclasts<span> and it will stimulate osteoblasts within minutes. The effect of this on osteoclast will cause a decrease in reabsorption and a concurrent increase in deposition because of the osteoblasts activity.</span>
