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.
Adenosine triphosphate (ATP) is the molecule with the greatest amount of stored energy in its bonds. When ATP is broken down, energy is released for cellular processes.
Oxygen is not an energy molecule itself, but it is essential for the process of producing energy in our cells through cellular respiration. Glucose is a common energy molecule that is broken down with the help of oxygen to produce ATP, the primary energy currency of the cell.
Carbohydrate, lipids, or proteins can be broken down to make ATP. Carbohydrates are the molecules most commonly broken down to make ATP.
Cellular RespirationSource: Holt Biology by Johnson Raven* Aerobic cellular respiration. Anaerobic cellular respiration yields a net gain of 2 ATP molecules for each glucose molecule broken down. Aerobic respiration yields a variable number, but always more than ten times as many ATP molecules.
Most probably(but a cookie does not die) because the stomach contains acids and the break down the cookie into a liquid and after that your pancreas produces more enzymes and the cookie gets broken down even more.
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 atoms are broken down into three parts. The atom consists of an electron, proton, and a neutron. The type of atom molecule determines how many of the protons, neutrons, and electrons are present.
Most trimmers,can be partially broken down for cleaning and repair.
The molecule that provides the body with the most energy is adenosine triphosphate (ATP). It is produced during cellular respiration in the mitochondria and serves as the primary energy currency of the cell. When ATP is broken down into adenosine diphosphate (ADP) and inorganic phosphate, energy is released for various cellular processes.
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.
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.
