Complicated question.
It's somewhat dependent on the available food. In a perfect world (ie: one where every type of nutrient is available in abundance), our bodies prefer glucose, as do most fauna.
Plants are a little different -- they don't "break down" in the way you're thinking, although they do use carbon dioxide in the air and water from the ground to produce ATP, as well as glucose, which we use as an energy source. Think of plants and animals as inversions of each other -- we break down glucose and put out carbon dioxide, and they break down carbon dioxide and put out glucose.
We can also burn practically anything for energy to make ATP. Energy from the breaking of chemical bonds is used (to create the MOST ATP, but this isn't the only way to make it) to create an electrical charge across a membrane to drive the formation of ATP. This can include the breakdown of protein and fats, as well as carbohydrates (simple and complex sugars) that aren't glucose.

Carbohydrates, fats, and proteins are broken down to make ATP. Carbohydrates are most often broken down to make ATP because they are the body's preferred source of energy due to their quick and efficient conversion into ATP through glycolysis and the citric acid cycle.
Large insoluble molecules get broken down into smaller soluble molecules through processes like digestion, hydrolysis, or decomposition. This allows the body to absorb and utilize the essential nutrients present in these molecules.
most neurotransmitters are not actually broken down, rather they are actively transported back into their pre release vesicles (this is called reuptake). Some neurotransmitters are broken down by a specific enzyme into non active parts i.e acetylcholine broken down by acetylcholinestarase
Biologically, glucose provides the most ATP when broken down through cellular respiration. Each glucose molecule can yield up to 36-38 ATP molecules depending on the efficiency of the process.
Most red blood cells die in the spleen, where they are filtered out and broken down by the body.
Carbohydrate, lipids, or proteins can be broken down to make ATP. Carbohydrates are the molecules most commonly broken down to make ATP.

When cell needs energy then the first molecule which is used is Glucose . If glucose level is low then Glycogen is broken down to get glucose . If glycogen is also in less amount then fats are broken down to get energy . Even then energy is needed then at last body Proteins are used up .
Most trimmers,can be partially broken down for cleaning and repair.
Most food needs to be broken down into smaller molecules so that it can be absorbed by the body. These smaller molecules can then be transported through the blood to cells where they are used for energy, growth, and repair. Breaking down food also helps to release nutrients and make them accessible for the body to utilize.
Steak and most meats contain mostly protein and fat. The protein is broken down to amino acids and the fat is broken down to fatty acids and glycerine.

Broken wrists and broken arms and broken legs. but i think most people will at one time or another experience a broken heart.

In humans, food is most broken down in the stomach where enzymes, bacteria and acids break the food into simpler parts. The food is then passed to the intestines, where the nutrients are absorbed.
Large insoluble molecules get broken down into smaller soluble molecules through processes like digestion, hydrolysis, or decomposition. This allows the body to absorb and utilize the essential nutrients present in these molecules.
Carbohydrates are broken down into glucose in your body.
