What else can I help you with?
When proteins are used as energy sources their breakdown subunits usually enter?
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.
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 of the following do not enter the cellular respiration pathways?
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.
What is protein respiration?
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.
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.

How do proteins enter the nucleus?
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.
What type of transport takes place when a proteins allow an ion to enter a cell but no additional energy is needed to make this happen?
facilitated
Where can Amino acids enter the metabolic pathways?
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.
Do large proteins containing a nuclear localization signal bind to the nuclear pore and enter the nucleus without any expenditure of energy?
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.
Do protein make energy molecules?
They can. In cellular respiration proteins may be broken down and modified to enter as part of the citric acid (Krebs) cycle.
What defines the term routes of entry?
the pathways by which hazardous materials may enter the body
Where does the common catabolic pathway take place?
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.
