The amount of energy released by any biomolecules is determined by how many ATP molecules are generated after the oxidation of that biomolecule, because the energy released during oxidation is saved in the form of ATP molecules.
A glucose molecule on oxidation yields total 38 molecules of ATP that are formed after glycolysis, TCA Cycle and ETS. The number of carbon atoms in glucose is 6.
Now consider a 6 Carbon Fatty acid molecule. It will undergo two beta oxidation cycles and will yield 3 Acetyl CoA molecules. Now, in each step of beta oxidation one NAD molecule is converted into NADH and H+ and one FAD molecule is reduced in FADH2. When these NADH and FADH2 molecules release their electrons in the Electron Transport Chain, they together cause the formation of 4 ATP molecules. Thus each step of beta oxidation will lead to formation of 4 ATP molecules. Thus if there are two steps of beta oxidation then there are 8 molecules of ATP.
Now the three Acetyl CoA molecules formed also enter the TCA cycle and each cycle will lead to generation of 30 more ATP molecules. Thus, totally, 38 ATP molecules are formed. The number of ATPs formed, goes on increasing as the number of carbons in the fatty acid molecules is increased.

How are lipids like carbohydrates?
lipids contain energy just like carbohydrates,but lipids contain more energy Source: North Shore Community College Student Carbohydrates do contain energy but only for short periods of time, where as Lipids can contain energy for long periods of time even if this means that they are under-water.
Why under aerobic respiration lipids have a greater energy value per mass than carbohydrates or proteins?
Lipids have a greater energy value per mass than carbohydrates or proteins because they are more reduced molecules, meaning they contain more carbon-hydrogen bonds that can be oxidized to release energy. This results in a higher energy yield during aerobic respiration. Additionally, lipids contain more energy-dense fatty acids compared to the sugars and amino acids found in carbohydrates and proteins, respectively.
What contains most energy protein lipids or carbohydrates?
Fats (lipids) contain the most energy per gram compared to proteins and carbohydrates. While proteins and carbohydrates provide 4 calories per gram, fats provide 9 calories per gram. So, gram for gram, fats contain more than twice the energy of proteins and carbohydrates.
How much energy do lipids release?
Lipids, as compared with carbohydrates, are much more reduced (i.e., there are many more C-H bonds and far fewer C-OH or C=O bonds).Because of this greater degree of reduction, lipids store more energy per gram than do carbohydrates (nine vs. four, respectively).
Which macromolecule contains the most energy?
Lipids store more energy per gram than carbohydrates or proteins.
What prohibits lipids from being a readily available energy source?
Lipids are not as readily available as carbohydrates for energy because they require more processing to be broken down into usable energy compared to carbohydrates. Additionally, the conversion of lipids to energy is slower and requires more oxygen than the breakdown of carbohydrates.
How much energy do lipids store as compared to carbohydrates?
lipids contain much more energy then carbohydrates. One gram of lipids create an average of 423 ATP or 0.47 mol ATP/gram. Glucose, with a molecular weight of 180.16, generates only 36 ATP, or 0.20 mol ATP/gram

Why do lipids store more energy than carbohydrates?
I don't really know what you're asking, but I'll do my best. The body stores both lipids and carbohydrates. Carbohydrates are more readily metabolized, but lipids are far more energy-dense- they can store far more energy per gram.
Are lipids a huge source of energy?
Yes, lipids are a concentrated source of energy, providing more than twice the amount of energy per gram compared to carbohydrates and proteins. When broken down, lipids release large amounts of ATP, which is the primary energy currency of cells.

Do lipids provide a quick source of energy?
Lipids do not provide a quick source of energy compared to carbohydrates. Lipids are more efficiently stored in the body for long-term energy use, while carbohydrates are the body's primary source of quick energy due to their rapid breakdown into glucose.
Carbohydratyes store more energy in bonds between its atoms than lipids?
No. Long chains of hydrocarbons, basically what lipids are, store much more energy in the bonds than carbohydrates do.
Why do animals use lipids instead of carbohydrates as energy-storing molecules?
Lipids have around twice the energy density of carbohydrates, so they are a more efficient means of storage (i.e. only half the mass is needed to store an equivalent amount of energy).
