Human sex cells, or gametes, are produced early in the developing embryo. ... They initially develop only body (somatic) cells, each with a full complement of chromosomes. When the time comes to mate, they produce their sex cells, or gametes, as needed by forming them out of stem cells from adult tissue.
Answer:
The correct answer is True
Explanation:
<u>The first step in glycogen synthesis (glycogenesis) is the phosphorylation of glucose to form glucose-6-phosphate</u>, which is catalyzed by hexokinase. [This step is also the first step in the glycolytic pathway]. Glucose-6-phosphate is then isomerized to glucose-1-phosphate by the action of phosphoglucomutase. This glucose-i-phosphate is then converted to glycogen by glycogen synthase.
The answer is C.
It is the site of gas exchange in the lungs.
Gas exchange occurs only in alveoli. Alveoli are made of thin-walled parenchymal cells, typically one-cell thick, that look like tiny bubbles within the sacs. Alveoli are in direct contact with capillaries (one-cell thick) of the circulatory system.
