Glucose molecules provide energy to power the swimming motion of sperm. In this example, the sperm are changing

From the energy stored in food substance( glucose) as Chemical energy to the energy of motion,which is Kinetic energy.

Explanation:

The energy is produced in the mitochondria which are packed in the flagellum of the  a sperm cells.Thus as the sperms move the these flagella flips  back and forth,Energy inform of ATPs are generated from the glucose(chemical energy) during cellular respiration in the mitochondria, this  energy is converted to  Kinetic energy for motility.

Specifically,ATP production for the sperm cells is initiated by  Glycolysis. This is because the environments where it swims to meet the ovum punctuates with in oxygen, besides,Glycolysis can occur with or without oxygen.

Sperm motility is very important to male fertility.

hypoxemia refers to a below usual concentration of oxygen in the blood, mainly in the arteries. hypoxemia is an indication of an issue associated with circulation or breathing and may lead to various symptoms like shortness of breath.  

the condition is identified by determining the level of oxygen in the blood sample obtained from an artery. it can also be predicted by determining the oxygen saturation of the blood with the application of a pulse oximeter.  

the normal arterial oxygen is about 75 to 100 mm hg. the values underneath 60 mm hg is generally considered with the requirement for supplemental oxygen. the normal pulse oximeter readings generally range between 95 to 100 percent. the values under 90 percent are regarded as low.  

in the given case, the oxygen saturation is measured at 93 percent, hence, there is no need to administer oxygen, that is, one should withhold oxygen.
