Before fats can be metabolized in aerobic cellular respiration they must be converted to?
Fats must be converted to fatty acids and glycerol before they can be metabolized in aerobic cellular respiration. This breakdown process occurs in the cytoplasm of the cell through a series of enzymatic reactions. Once converted, fatty acids can enter the mitochondria to undergo beta-oxidation and produce acetyl-CoA for the citric acid cycle.
What is the chemical formed when fats are metabolized?
When fats are metabolized, they are broken down into molecules called fatty acids and glycerol. These molecules can then be further metabolized into a compound called acetyl-CoA, which enters the citric acid cycle (also known as the Krebs cycle) to produce energy through cellular respiration.
Which chemical apart from glucose is used in respiration?
Apart from glucose, fatty acids and amino acids can also be used in cellular respiration. Fatty acids undergo beta-oxidation to produce acetyl-CoA, which enters the Krebs cycle, while amino acids can be deaminated and converted into various intermediates that participate in the energy-generating pathways. Additionally, other carbohydrates like fructose and galactose can also be metabolized for energy.
Do fatty acid chains contain the most energy?
Yes, fatty acid chains contain the most energy among macronutrients. They are highly reduced molecules, meaning they have a greater number of hydrogen atoms relative to oxygen, which results in a higher energy yield when metabolized. When oxidized during cellular respiration, fatty acids release more ATP compared to carbohydrates and proteins, making them a dense source of energy for the body.
Energy used in cellular respiration can originate from?
Energy used in cellular respiration can originate from glucose, fatty acids, or amino acids, which are broken down through various metabolic pathways to produce ATP. This energy is then utilized by cells to carry out essential biological processes.

Is fat used in cellular respiration?
Fats can be used in cellular respiration. Fatty acids can produce Acetyl-CoA (through beta-oxidation), which is an important reactant in cellular respiration. This Acetyl-CoA then enters the Citric Acid Cycle. The main source of Acetyl-CoA for cellular respiration is glucose, however fatty acids can also be used.

Fatty acids are metabolized by what pathway?
Beta-oxidation is the major pathway by which fatty acids are metabolized. However, there are other minor pathways for fatty acid metabolized. These include alpha-oxidation (for branched fatty acids) and omega-oxidation.
Carbon skeletons to be broken down during cellular respiration can be obtained from?
Carbon skeletons for cellular respiration can be obtained from glucose, fatty acids, and amino acids. These molecules are broken down in different metabolic pathways to generate energy in the form of ATP.
Can other molecules besides glucose be used in cellular respiration?
Yes, other molecules besides glucose can be used in cellular respiration. Fatty acids and amino acids can also be broken down in specific pathways to generate ATP through cellular respiration. Each type of molecule enters cellular respiration at different points in the metabolic pathway.
Can cellular respiration take place without glucose?
Yes, cellular respiration can occur without glucose. While glucose is a primary energy source, cells can utilize alternative substrates such as fatty acids and amino acids to produce ATP. These substrates undergo different metabolic pathways, such as beta-oxidation for fatty acids and deamination for amino acids, to eventually enter the citric acid cycle and oxidative phosphorylation. Therefore, while glucose is common, it is not the sole fuel for cellular respiration.
How does the human body obtain reactants for cellular respiration?
The human body obtains reactants for cellular respiration through the digestion of food. Carbohydrates, fats, and proteins from the food we eat are broken down during digestion into glucose, fatty acids, and amino acids, which are then used as reactants in cellular respiration to produce energy in the form of ATP.
