Answer:
From fertilization and to the end of the second week.
Explanation:
The development of the fetus is divided into three periods, established by most embryologists: pre-embyonic period, which goes from fertilization to the second week of development, embryonic period, which goes from the third week to the eighth week, and the fetal period, which goes from from the third month until the end of pregnancy.
The pre-embyonic stage begins at fertilization and remains until gastrulation. By the end of the second week the embryo already has the neural tube formed, although it is still open at both ends.
Answer:
ATP is able to power cellular processes by transferring a phosphate group to another molecule (a process called phosphorylation). This transfer is carried out by special enzymes that couple the release of energy from ATP to cellular activities that require energy. ATP is the immediately available source of energy for almost all bodily functions, including muscle contraction. It is formed when a phosphate group is added to ADP during phosphorylation, a process that requires a considerable amount of energy. ATP is also formed from the process of cellular respiration in the mitochondria of a cell. This can be through aerobic respiration, which requires oxygen, or anaerobic respiration, which does not. Aerobic respiration produces ATP (along with carbon dioxide and water) from glucose and oxygen. What are the 3 steps to energy exchange from ADP to ATP?

Quiz
ATP consists of adenosine and two inorganic phosphates.
When ADP is broken down into ATP, energy is released.
ATP is synthesized by the cell through cell respiration.
In the absence of oxygen, respiration occurs in the following steps: Glycolysis, Kreb's Cycle, and Cytochrome System.
