Which substances serves as an intermediate through which all cellular energy sources are interconvertible?
Acetyl-CoA is the central metabolic intermediate through which all cellular energy sources, such as carbohydrates, fats, and proteins, can be converted into energy in the form of ATP through processes like the citric acid cycle and oxidative phosphorylation. It plays a crucial role in linking various metabolic pathways.
What do plants use to to make fats?
Plants use carbohydrates, primarily glucose, as a building block to synthesize fats. Through a process called lipogenesis, glucose is converted into fatty acids, which are then combined with glycerol to form lipids or fats. Additionally, plants utilize various nutrients, such as nitrogen and phosphorus, to support this metabolic process.
What stage of cellular respiration do fats proteins and carbohydrates enter the metabolic pathway?
Fats, proteins, and carbohydrates enter the metabolic pathway of cellular respiration during the acetyl-CoA formation stage. Fats and carbohydrates are broken down into acetyl-CoA through different pathways, while proteins are converted into amino acids, which can then enter the acetyl-CoA formation stage.
Which term describes the brokendown of stored fats into glycerol and fatty acids?
The term that describes the breakdown of stored fats into glycerol and fatty acids is "lipolysis." This process is primarily facilitated by enzymes called lipases and occurs in adipose tissue, where triglycerides are converted into free fatty acids and glycerol, which can then be used for energy production by the body. Lipolysis is a crucial metabolic pathway during periods of fasting or increased energy demand.
What molecule produces Acetyl-CoA?
Acetyl-CoA is primarily produced from the breakdown of carbohydrates, fats, and proteins. In carbohydrate metabolism, glucose is converted into pyruvate through glycolysis, which is then transformed into Acetyl-CoA via the pyruvate dehydrogenase complex. Additionally, fatty acids undergo beta-oxidation to yield Acetyl-CoA, while certain amino acids can also be converted into Acetyl-CoA through various metabolic pathways.

What forms of energy can be found stored in carbohydrates proteins and fats?
Carbohydrates, proteins, and fats store energy primarily in the form of chemical energy, which is released during metabolic processes. Carbohydrates are often quickly converted to glucose for immediate energy, while fats provide a more concentrated energy source due to their higher caloric content. Proteins can also be used for energy, but primarily serve as building blocks for tissues and enzymes. The energy stored in these macromolecules is harnessed by the body through cellular respiration and other metabolic pathways.
What stage of cellular respiration do fats proteins and carbohydrates enter the metabolic pathway?
Fats, proteins, and carbohydrates enter the metabolic pathway of cellular respiration during the acetyl-CoA formation stage. Fats and carbohydrates are broken down into acetyl-CoA through different pathways, while proteins are converted into amino acids, which can then enter the acetyl-CoA formation stage.
Can glucose fats and proteins be respired to yield ATP?
Yes, glucose, fats, and proteins can be respired to yield ATP through cellular respiration. Glucose is the primary source of ATP, while fats and proteins can also be broken down and converted into ATP through different metabolic pathways such as beta-oxidation for fats and gluconeogenesis for proteins.

Why do you fats?
Fats are an essential part of a healthy diet. Every cell and every metabolic process in the body needs fats directly or indirectly.
What are fats proteins and carbohydrates converted to?
They are converted to glucose. Excess is stored as fat.
What molecule produces Acetyl-CoA?
Acetyl-CoA is primarily produced from the breakdown of carbohydrates, fats, and proteins. In carbohydrate metabolism, glucose is converted into pyruvate through glycolysis, which is then transformed into Acetyl-CoA via the pyruvate dehydrogenase complex. Additionally, fatty acids undergo beta-oxidation to yield Acetyl-CoA, while certain amino acids can also be converted into Acetyl-CoA through various metabolic pathways.
Why do you nedd fats?
Fats are an essential part of a healthy diet. Every cell and every metabolic process in the body needs fats directly or indirectly.
Where can cell energy be extracted from?
Cell energy can be extracted primarily from three sources: carbohydrates, fats, and proteins. Carbohydrates are broken down into glucose, which is then utilized in cellular respiration to produce adenosine triphosphate (ATP). Fats are metabolized through beta-oxidation, also leading to ATP production, while proteins can be converted into amino acids that enter various metabolic pathways for energy extraction. Overall, these macromolecules serve as fuel for cellular processes, enabling growth and maintenance.
Can unused fats be turned into carbohydrates?
Not technically. Enzymes split the triglyceride molecules into glycerol and three fatty acids. Glycerol is then converted into PGAL, an intermediate in glycolysis in the cytoplasm. The fatty acids are converted into Acetyl Coenzyme (Acetyl CoA), and enter the Krebs cycle in the mitochondria. The ATP yield is roughly 32-38 molecules of ATP.
