<reasoning>

Analyze cellular glucose uptake

Using the Endocrine Disorders and Insulin Secretion knowledge points

• Insulin acts as a key to let glucose enter most body cells (such as skeletal muscle and adipose tissue) via GLUT4 transporters.
• Without functional insulin or adequate insulin levels, these cells cannot take up glucose, leading to high extracellular blood glucose levels while the cells starve.

Evaluate the brain's glucose usage

Using the Diabetes Mellitus Epidemiology knowledge point

• The brain is an insulin-independent organ that relies on GLUT1 and GLUT3 transporters for glucose uptake.
• It does not require insulin to utilize glucose from the bloodstream.

Evaluate the remaining options

• Glucose will be stored as fat: In a diabetic patient with high blood glucose (hyperglycemia) due to lack of insulin action, glucose cannot enter adipose cells efficiently to be converted and stored as fat.
• Alkalosis prevents cells from using oxygen: Severe hyperglycemia typically leads to diabetic ketoacidosis (acidosis, not alkalosis), and this statement is physiologically incorrect in this context.
• Most cells require insulin to process glucose: This is correct because the majority of peripheral body cells require insulin-mediated signaling to transport glucose across their membranes.
