Which cells are obligate glucose users?

  1. Liver cells

  2. Muscle cells

  3. Red blood cells

  4. Brain cells

The correct answer is: Red blood cells

Red blood cells are the only cells in the body that are considered obligate glucose users, meaning that they rely on glucose as their main source of energy. Liver cells, muscle cells, and brain cells are all able to use other energy sources such as fats and proteins in addition to glucose, making them facultative glucose users. This means that they can still function properly even if they do not have access to glucose. Therefore, B, C and D are incorrect choices.
