When proteins are broken down for energy, their subunits usually enter metabolic pathways such as the citric acid cycle to be further broken down into molecules like acetyl-CoA. These molecules can then be used to produce ATP through oxidative phosphorylation in the mitochondria.
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.
To accurately answer your question, I would need a list of options to determine which substances do not enter the cellular respiration pathways. Generally, substances like fatty acids, amino acids, and glucose do enter these pathways, while substances that are not energy substrates, such as certain waste products or non-nutrient compounds, do not. Please provide the specific options for a more precise response.
Protein respiration refers to the process by which proteins are broken down into amino acids and subsequently utilized by cells to generate energy. This process occurs during cellular respiration, where amino acids can enter the metabolic pathways, such as the Krebs cycle, after being deaminated. While carbohydrates and fats are the primary energy sources, proteins can be used when other sources are scarce. Ultimately, protein respiration contributes to the overall energy production and maintenance of cellular functions.
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.

Proteins enter the nucleus through nuclear pores in the nuclear membrane. These pores allow specific proteins to pass through and enter the nucleus where they can perform their functions.

Amino acids can enter metabolic pathways through conversion into intermediates such as pyruvate, acetyl-CoA, or enter the citric acid cycle directly at various points depending on the specific amino acid and metabolic need of the cell. The breakdown of amino acids provides both ATP energy and carbon skeletons for biosynthesis.
No, proteins with a nuclear localization signal require energy to actively transport through the nuclear pore complex into the nucleus. They are not able to enter the nucleus passively. The binding and translocation through the nuclear pore are facilitated by specific transport receptors and require energy in the form of GTP hydrolysis.
They can. In cellular respiration proteins may be broken down and modified to enter as part of the citric acid (Krebs) cycle.
the pathways by which hazardous materials may enter the body
The common catabolic pathway primarily takes place in the cytoplasm of cells. This pathway involves the breakdown of larger molecules into smaller units to release energy for cellular activities. The final products of this process can then enter other metabolic pathways to generate ATP.
