The energy stored in the bonds of any fat based molecule, or lipid, is greater than that of a carbohydrate molecule. Simple carbs are easily broken down for quick bursts of energy, while complex carbs take longer to break down. Fats on the other hand, are all more difficult to digest because of the size of their molecules and the complexity of their structure. Fats are also stored more rapidly; they are the body's emergancy power source.
What else can I help you with?
Why do carbohydrates in the mitochondria produce more ATP than those outside the cell?
Because oxidation is complete. Much energy is conserved.
Does Metabolism of fats produce more ATP molecules per gram than metabolism of carbohydrates or proteins?
When it comes to carbohydrates or fats producing more ATP, fats tend to produce more ATP per gram. Fats contain about 33 percent more ATP than carbs.
Do triglycerides store more or less energy than carbohydrates?
Triglycerides store more energy than carbohydrates. This is because they are more calorie-dense molecules due to their higher number of carbon-hydrogen bonds, making them a more efficient energy storage form in the body.
Can some autotrophs obtain their energy from chemicals rather than sunlight to produce carbohydrates?
Yes, hydrogen sulfide
Explain that Oxidation of fats in living cells release more energy per gram than the oxidation of carbohydrates?
Fats are more reduced than carbohydrates, therefore there is more oxidation that occurs in the breakdown of fats, and hence, more energy is produced.
How much more energy does fat supply than carbohydrates?
Fats actually contain a lot more energy than carbohydrates. The reason carbohydrates are used for energy before fats is because carbohydrates are easier to break down; reactions involving carbohydrates generally have a lower activation energy. This means that less energy is used to release the energy in the bonds of the carbohydrates than fats. In other words, although fats contain more energy, it is more efficient for the body to break down carbohydrates than fats. Once carbohydrate supplies diminish, fat stores can be broken down to use for energy, but doing so is not the body's favorite thing to do.
Why do fats have more energy than carbohydrates and proteins?
Fats have more energy because they contain more carbon-hydrogen bonds, which store more energy than the oxygen-hydrogen bonds found in carbohydrates and proteins. When these bonds are broken during metabolism, fats release more energy in the form of ATP, making them a more efficient energy source.
Why do apples produce more energy than lemons?
Apples have higher sugar content than lemons, which results in more energy when consumed. Sugar is a source of carbohydrates that provide energy to the body through the process of cellular respiration. Lemons have lower sugar content and higher acidity, which can affect the overall energy production when consumed.
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.
Do fats contain large amounts of energy per gram?
Fats provide a form of store energy. Fats can provide more than half the energy that the body needs and twice as much as than carbohydrates
What has more potential energy carbon dioxide carbohydrates or fatty acids?
Fatty acids have more potential energy than both carbon dioxide and carbohydrates. This is because fatty acids contain more carbon-carbon and carbon-hydrogen bonds, which store more energy per molecule. When broken down in the body, fatty acids release more energy than either carbon dioxide or carbohydrates.
Why are fats a better source of energy than carbohydrates on a per carbon basis?
Fats are a better source of energy than carbohydrates on a per carbon basis because fats contain more carbon-hydrogen bonds, which store more energy when broken down compared to the carbon-oxygen bonds in carbohydrates. This means that fats provide more energy per carbon atom when metabolized.
