Answer:
DNA polymerase
Explanation:
The process in which DNA make its copies is called DNA replication.
It is true that DNA do not have any catalytic activity in the cells but there are several enzymes which participate in the process of DNA replication and performs different functions. DNA Polymerase is one of the key enzyme that participate in the process and catalyzes the formation of phosphodiester bonds between adjacent nucleotides in the DNA.
Arthur Kornberg in 1956 discovered DNA polymerase along with his colleague in Escherichia coli. DNA Polymerase catalyzes the addition of phosphodiester bonds with the help of formation of hydrogen bonds between the adjacent strands of DNA and build the backbone of DNA. Other functions of DNA polymerase involves synthesis of DNA from the RNA primers , helps in the elongation of leading strand, and DNA sequencing.
Hence, DNA polymerase is catalyzes the formation of phosphodiester bonds between adjacent nucleotides in the DNA.
Hormones are secreted and released into the blood by Endocrine glands.
Endocrine glands are glands of the endocrine system that secrete their products, hormones, directly into the blood rather than through a duct. The major glands of the endocrine system include the pineal gland, pituitary gland, pancreas, ovaries, thyroid gland, parathyroid gland, hypothalamus and adrenal glands.
Answer:
calcitonin
Explanation:
Calcitonin is a hormone which helps in lowering the high blood calcium levels. It is secreted by thyroid glands. Parathyroid glands are responsible for increasing calcium level in the blood while calcitonin hormone work against parathyroid glands and helps in lowering calcium level. Calcitonin hormone inhibit the activity of osteoclasts which are responsible for releasing of calcium from bones into the blood.
I think the veins absorb the photons because they're located at the top part of a leaf while the stomata that serves as the leaf's lungs are found at the under side.
The Answer is Electrons
ATP also is known as adenosine triphosphate, refers to a molecule found in the cells of all the living species. It is considered to be very essential as it helps in transporting the energy that plays an essential role in all the cellular metabolic activities. The mentioned reaction is the second step of the Calvin cycle, also termed as reduction step. During the process, the electrons from NADPH and ATP are transferred to 3-PGA, which further gets reduced to produce G3P or glyceraldehyde-3-phosphate. Thus, ATP is providing electrons in the mentioned reaction.
