what tissue only uses glucose as an energy source?

Answer 1

if i remember my biology correctly (from school a few years back), i learnt that only the brain use glucose as energy source. If you don't eat, blood glucose level drops and you faint. The horizontal position makes it easier for blood carrying glucose to reach the brain (not flow against gravity as when you are standing up).
Energy sources in body: First body uses glucose, when glucose level drops then stored excess sugar from glycogen is used. Then ketosis occurs (use fatty acids as fuel) when glycogen store is exhausted.

Hope it helps.

Answer 2

I'm Not Sure if Any Tissue (Assuming you Are Referring to the Human Body) Exclusively Uses Glucose, this Suggests Exclusive Anaerobic Functioning, the Brain was, At One Time, Thought to Use Only Glucose, but it has Since Been Discovered that it Uses Ketone Bodies (Perhaps Preferentially) as Well.

Answer 3

A certain amount of calories are needed to supply the energy required for everyday activities and metabolism (the chemical process by which the body converts food into energy and various functions, including food digestion, circulation, and temperature regulation). When more calories are consumed than are needed, these extra calories are stored primarily as fat--whether the calories come from fat, carbohydrates, or proteins.

During digestion, enzymes in the small intestine break down carbohydrates into simple sugars like glucose, proteins into amino acids, and triglycerides (dietary fat) into fatty acids and glycerol. Simple sugars and amino acids are rapidly absorbed from the small intestine into the bloodstream. The liver converts other sugars, like fructose and lactose, into glucose, which is used as a source of energy. Amino acids can be used as an energy source but serve mainly as building blocks for body proteins. Fatty acids combine with bile salts to form tiny droplets that promote their entry into cells in the intestinal wall, where they are again formed into triglycerides. The triglycerides are packaged into transport lipoproteins, which carry the triglycerides to the adipose tissue (fat) for storage.

Answer 4

Type tissues that use glucose as energy at yahoo search some interesting links are there see if that answers your question.

Answer 5

Glucose is used predominantly in the brain. However, it does make sense what the guy above said about ketones being used. But, my vote is the brain.

Answer 6

brain, but, quite obviously, many other substances can cross the brain barrier and change the brain's chemistry. In the case of alcohol or drugs, the changes can be permanent.

Answer 7

In normal functioning i assume the heart would since you don't want the heart to go into oxygen debt

Answer 8

muscular tissue...i suppose.
