They rely on glucose for energy.
They get energy from sugars.

All metabolic functions in the body require ATP to proceed. ATP is the energy currency of the cell; all other energy sources must first be converted to ATP before they are able to yield energy. All organs can convert glucose to ATP for use as energy, except for the brain. The brain is the only organ that cannot use other energy sources for fuel (fats, proteins, fructose, glycogen, etc). ONE EXCEPTION: is that the brain can run on ketones during starvation. My degree is in Kinesiology, not physiology, and I'm answering this off the top of my head, so use this answer for informational purposes only. Marcus Just to add a little; fatty acids cannot pass the blood brain barrier, so only glucose can be used by the brain. Red blood cells don't have a mitochondria, so they also rely solely on glucose. The kidney medulla, lens of the eye, and tests have very little mitochondria, so they depend almost entirely on glucose.
No, white blood cells are not eukaryotes.Eukaryotes are organisms that have eukaryotic cells. People are eukaryotes, with many millions of eukaryotic cells.White blood cells are eukaryotic cells in eukaryotes.
Erythrocytes (red blood cells) have no cellular organelles - they have pushed all of them out to make more room for hemoglobin to carry oxygen. Therefore, the RBC must rely on anaerobic respiration for its energy needs because it gave up the mitochondria that would have performed aerobic respiration.
The red blood cells in the body completely rely on glucose, which is a carbohydrate, for energy. Adipose tissue and muscles cells partially rely on glucose as well.

Yes--the heart. The blood pumped from the heart provides the brain with vital oxygen.
Red blood cells (RBCs) have an anaerobic metabolism. They lack mitochondria, which are responsible for aerobic metabolism, so RBCs rely solely on anaerobic processes to produce energy. RBCs primarily generate energy through glycolysis, converting glucose into ATP to fuel their functions.
Cell respiration requires the process of energy and cells rely on active transport to provide the amount of energy.
The human body primarily uses glucose, a type of simple sugar, for energy. We convert the energy stored in glucose into a molecule called ATP which is what powers most of our cellular activity.
Glucose is used by the body as a primary source of energy. Red blood cells and neurones rely entirely on glucose for energy. Excess amounts of glucose in the body is converted to glucogon or fat and stored for later use.
