They enter the Krebs Cycle.

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 and proteins can enter the pathways of energy release through different mechanisms. Fats are broken down into fatty acids through a process called beta-oxidation, which then enter the citric acid cycle to produce energy. Proteins are broken down into amino acids, which can be converted into various intermediates that enter the citric acid cycle for energy production.
External sources of energy entering the Earth system include solar radiation and cosmic rays. Solar radiation, the primary external energy source, drives various processes and is essential for sustaining life on Earth. Cosmic rays, though less significant than solar radiation, also contribute to the energy balance of the planet.
Triglycerides are broken down through a process called lipolysis, which involves the release of fatty acids and glycerol. These components can then enter metabolic pathways to produce energy through processes like beta-oxidation and the citric acid cycle. The fatty acids are oxidized to generate ATP, which can be used by the body as an energy source.
They can. In cellular respiration proteins may be broken down and modified to enter as part of the citric acid (Krebs) cycle.
In a closed system, energy can be transferred between different components within the system but does not enter or leave the system. This means the total energy within the system remains constant, in accordance with the principle of conservation of energy.
how does energy enter this living world
Starch is too big to enter cells, so it is broken down into smaller molecules like glucose outside the cell. These smaller molecules can then be transported into the cell for energy production.
The simple bodies that enter originally into the composition of mixtures are called elements. Elements are substances that cannot be broken down into simpler substances by chemical means and are the building blocks of all matter.
For carbohydrates to be oxidized or burned for energy, they must first be broken down into simple sugars (glucose) through the process of digestion. Glucose can then enter cells and undergo further processes such as glycolysis and the citric acid cycle to produce energy in the form of ATP.
Nutrients that enter your cells are broken down from the food you eat during digestion. The nutrients are then absorbed into the bloodstream and transported to cells for energy production, growth, repair, and maintenance. The cells use these nutrients to carry out their functions and support overall health.
