Thyroid calcification is the formation of a solid or semi-solid lump within the thyroid gland. In most cases, a calcified thyroid is a benign, meaning noncancerous, condition that may not present any symptoms. Treatment for thyroid calcification is dependent on the type of nodule and the overall health of the individual.
Cellular respiration is the chemical reaction in which glucose and oxygen are turned into water, carbon dioxide, and energy (ATP). In this reaction, glucose and oxygen are reactants, while water, carbon dioxide, and energy (ATP) are products. Reactions can be represented as chemical equations where chemical formulas are used as shorthand to show the reaction.
In order to create ATP, your body takes in oxygen and glucose as reactants. Cellular respiration can be seen as a chemical reaction that changes reactants into products. In the chemical equation below, reactants are on the left of the arrow and products are on the right. The main product of cellular respiration is ATP.
