No, although there are several theories with increasing evidence, there is still no way to know for sure how it occurred. The great mystery of the beginning of universe is way too vast and vague. Theories can only be proven by presenting a solid proof, but great creations such as universe itself doesn't have to be solved. Various possibilities must have happened or there must be a one conclusion leading to its existence; but moreover, it is not our problem to solve. The confirmation of beginning of its existence will only feed the curiosity of humans.
Answer: The correct answer for the blank is-
Energy is released from ATP ( adenosine triphosphate) when high energy phosphoanhydride bond ( present between two phosphate) is broken down or hydrolyzed.
This results in the formation of ADP ( adenosine diphosphate) and Pi ( inorganic phosphate).
Therefore, hydrolysis of ATP releases energy.
In some cases, massive destruction of red blood cells caused death. This drug-induced hemolytic anemia was shown 30 years later to be caused by a deficiency of glucose 6-phosphate dehydrogenase, the enzyme catalyzing the first step in the oxidative branch of the pentose phosphate pathway.
in short terms, glucose 6-phosphate dehydrogenase
The Prostate gland
The prostate is a walnut-sized organ that surrounds the
first part of the urethra. It is located between the bladder and the penis. Semen
is formed by the prostate by combining a thick white fluid it initially produced
with the sperm from the testicles. It also produces an antibiotic protein known
as prostate-specific antigen (PSA) that changes the semen into liquid.
