What percentage of glucose is normally found in human blood?
- A
0.008
- B
0.0008
- C
0.018
- D
0.08
In human blood, glucose is typically found at a concentration of about 0.08%. This is the standard level needed for maintaining normal bodily functions, such as providing energy to cells. Option A (0.008%) and Option B (0.0008%) suggest concentrations far lower than the norm, which are not sufficient for normal physiological processes. Option C (0.018%) is closer but still below the typical range. Therefore, the correct answer is Option D, 0.08%, which accurately reflects the normal glucose concentration in blood.
This option is incorrect. 0.008% would indicate a much lower concentration than what is normally found in human blood. The typical concentration is higher, around 0.08%.
This option is incorrect. 0.0008% is far too low for the normal glucose concentration in human blood. The correct answer is significantly higher.
This option is incorrect. 0.018% is still lower than the typical concentration found in human blood, which is around 0.08%.
This option is correct. The normal glucose concentration in human blood is approximately 0.08%. This reflects the typical glucose level required for proper metabolic function.
