Answer: D
Explanation: endocrine gland cells that secrete hormones (chemical messengers), which are carried in the bloodstream to the target cells which they act upon
The answer to this question would be: half of
Gametes cell is a haploid cell that only has half of genetic material from the parent cells. The process of making gamete cells is called meiosis.
The gamete is haploid because it was used in fertilization and need to fuse with other gametes(example: sperm with the egg) resulting in a full paired chromosomes.
Answer:
Option-A
Explanation:
Pentose phosphate pathway is the alternative pathway taking place in both eukaryotes and prokaryotes parallel to the glycolysis.
The pentose phosphate pathway forms the electron carriers called NADPH and the ribose-5 phosphate.
The NADPH is formed in large amounts through this pathway which contains a very high amount of energy. NADPH can donate its hydride ions, therefore, it can be involved in the reaction where it can donate energy in the form of hydrogen and electron.
The NADPH is therefore involved in the formation of reducing biosynthetic pathways like fatty acid synthesis, cholesterol synthesis, and bile acid synthesis.
Thus, Option-A is the correct answer.
Answer:
The oxygen enters the bloodstream from the alveoli, tiny sacs in the lungs where gas exchange takes place (Figure below). The transfer of oxygen into the blood is through simple diffusion. ... While oxygen moves from the capillaries and into body cells, carbon dioxide moves from the cells into the capillaries.
