Carbon is a reactant in the process of photosynthesis but a product in the process of cellular respiration.
<h3>What is carbon cycle?</h3>
Carbon cycle is the physical cycle of carbon through the Earth’s biosphere, geosphere, hydrosphere and atmosphere.
It is the series of processes by which carbon compounds are interconverted in the environment, that includes such processes as
- photosynthesis
- decomposition
- respiration
- carbonification
Carbon cycle involves the incorporation of carbon dioxide into living tissue by photosynthesis and its return to the atmosphere through respiration, the decay of dead organisms, and the burning of fossil fuels.
Therefore, carbon is present in the atmosphere as a reactant during photosynthesis and as a product during cellular respiration.

C cells of the thyroid gland secrete calcitonin.
<h3>
What does C cells of thyroid gland produce?</h3>
- The thyroid follicle, which is the gland's active component, is encircled by a single layer of epithelial cells, and the lumen is stuffed with colloidal material.
- It includes parafollicular cells, or C cells, which release calcitonin.
- The C-cells of the thyroid gland secrete calcitonin, a 32 amino acid hormone.
- When the concentration of blood calcium has grown over the usual range, the thyroid gland releases the hormone calcitonin, which lowers the level.
- The parafollicular cells, sometimes referred to as the C cells, of the thyroid gland are the principal producers of this polypeptide hormone, which has 32 amino acids.

Answer:
Sweating helps cool down the body. Water is released through glands in the skin, evaporates off the skin and the body is cooled. During exercise, muscles heat up more, so more sweat is needed.
