The thyroid gland regulates the body's metabolism (through T3 and T4) and also affects the metabolism of calcium through the production of calcitonin, which reduces calcium concentration of the blood.
The parathyroid glands, which are located within the thyroid gland, also affect the metabolism of calcium by producing parathyroid hormone PTH, which increases calcium concentration of the blood.
Endocrine gland - a group of cells that secretes substances into the blood or directly into an organ.
Differ from exocrine glands, endocrine glands have no ducts and secrete products (hormones) directly into blood.
Hormone - a substance produced by cells that helps specific groups of cells to perform specific functions. It is a product of endocrine gland which functions as chemical messengers to stimulate other cells.
Duct – a channel or tube that conveys a substance. It is part of the exocrine glands (such as salivary glands) which makes contact with surface .
The stomata open up to absorb the carbon dioxide needed to perform photosynthesis.
Survival of the fittest. The strongest offspring will survive to adulthood and reproduce - their offspring will have stronger genes than prior generations. The weaker offspring will not live to adulthood and not produce offspring, therefore the weaker traits will die out with each generation
Answer:
ATP consumed = 2 molecules
ATP produced = 2 molecules.
Explanation:
Arsenate does not produce 1,3-bisphosphoglycerate, so it can be deduced that at least two ATP molecules are produced through normal glycolysis, remembering that phosphoglycerate kinase allows the reaction between 1,3-bisphosphoglycerate transforming it into 3 -phosphoglycerate and generating two ATP, phosphoglycerate kinase catalyzes this reaction and gives 2 ATP.
