Answer: promoting the rapid resynthesis of ATP, by the action of creatine kinase.
Explanation:
Adenosine triphosphate (ATP) is the main form of chemical energy, its hydrolysis remaining highly exergonic. The maintenance of cellular homeostasis mechanisms, that adjust the generation processes of ATP, responds to the energy demand.
Creatine phosphate (CrP) was discovered in 1927 in the muscle tissue. Free creatine (Cr) is generated from the breakage of (CrP) during muscle contraction. Since the PCr / CK (Creatine kinase) system has a high rate of ATP generation, it is particularly important in situations of high metabolic demand, such as high-intensity physical exercise, when the ATP utilization rate exceeds its generation capacity by other metabolic pathways.
<u>Answer:
</u>
The day one starts with the first day of your periods when the blood and tissue lining the uterus (womb) break down and leave the body is considered to be the '1st day' of the 'female reproductive system'.
<u>Explanation:
</u>
- The periods, that is the 'first day of female reproductive system' starts during puberty and stops 'permanently at menopause'.
- The menstrual cycle starts with the 'first day of bleeding', which is counted as 'day one'.
- The menstrual cycle stops just before the "next menstrual period". Menstrual cycle normally ranges from 25 to 36 days.
- The periods may last anywhere from '3 to 8 days', but '5 days' is average.
