23. Describe which cell of the body are dependent upon glucose?


Answers:    I believe the answer you are looking for is beta cells.
can find more information on glucose contained by the body on the following web pages.

Good luck to you. Source(s): http://www.enjoying-life-with-diabetes.c…

Cells, not organs? Organs are made up of tissue which is made up of cells.

Sugar, or glucose is the bodies fuel and drives various functions. For one the body produces ATP, (is the universal form of energy) through cellular respiration, which is possible through the synthesis of glucose and oxygen (unless its anaerobic respiration) The mitochondria is the site for aerobic respiration, which are inside cells.

Every cell is dependent upon glucose as an energy source in the human body. However, in times of true starvation or "pseudostarvation" (like diabetes) the body is competent to convert to alternate energy source called ketones. Ketones provide energy from the break-down of lipids and are utilized as a dash source for the human body. In the case of starvation, protein and ketones are converted to glucose in the liver in establish to be used by red blood cells and the brain. Red blood cells are solely dependent upon glucose as RBC's are without a nucleus so they are incompetent to transcript genes to alter energy metabolism in time's of starvation stress so the liver provides glucose in times of dietary glucose depletion. The brain is equally dependent upon glucose for metabolism but is competent to convert it's metabolism to ketones when in desperate need (though it does this metabolic conversion after skeletal muscle and other organs). Eventually, if dietary needs are not met for an extended interval, the body will begin to break down organs and will be unable to sustain the energy requirements of the body and the starving individual will parish.
The beta cells the individual above mentioned are also dependent on glucose for metabolism but they have a one and only metabolic responsibility for the body. Once glucose (from a meal) is entered into the blood stream, glucose enters the beta cell for metabolism. Once the energy state of the cell have increased and there is adequate ATP (ultimate energy endpoint) the cell is competent to alter potassium channels in a way that allows the beta cell to depolarize and allow for the release of insulin. Insulin, as you know, help cells in the human body uptake glucose, proteins, and lipids. Source(s): Medical Stuent
