Plants use carbon dioxide from the air through photosynthesis to make carbohydrates, fats, and proteins. During photosynthesis, carbon is converted into glucose, which serves as the building block for carbohydrates. Fats and proteins are produced by further modifying glucose and incorporating other elements like nitrogen and sulfur.
Carbohydrates and fats are broken down in the digestive tract into the simple sugars, glucose, fructose, and galactose. The latter two can be converted by the body into glucose, which is distributed throughout the body via the bloodstream and is broken down into Carbon Dioxide and water in the mitochondria of cells. Proteins are broken down into their constituent amino acids, which are used to assemble new proteins throughout the body.
b Plant fats and c Animal proteins yield more than 4 kcalories per gram, with fats supplying 9 kcal/g and proteins providing 4 kcal/g. Plant carbohydrates and proteins usually provide 4 kcal/g or less.
Glucose is the primary source of energy for the body's cells, particularly the brain and muscles. It is essential for providing fuel for various cellular activities and metabolic processes. The body can convert carbohydrates, proteins, and fats into glucose to meet its energy needs.
Glucose is produced through the process of photosynthesis in plants, where sunlight, carbon dioxide, and water are converted into glucose. Protein and fats are synthesized in living organisms through the process of protein and lipid synthesis, which involves the assembly of amino acids into proteins and the synthesis of fatty acids and glycerol into fats.
Glucose is a primary energy source for the body and is used regardless of the availability of proteins and fats. It is the preferred energy source for many cells, particularly the brain and red blood cells. The body can use glucose from carbohydrates, proteins, and fats to meet its energy needs.
Beef jerky is made up of proteins.
Insulin
Gluconeogenesis
They are converted to glucose. Excess is stored as fat.
Acetyl-CoA can yield energy the quickest in the citric acid cycle. Acetyl-CoA is derived from the breakdown of carbohydrates, fats, and proteins, and it enters the citric acid cycle to produce ATP, which is the cell's primary energy source.
Gluconogensis is a metabolic pathway that creates glucose, which is a building block of the body, from things that are not glucose, like fats and proteins.
Fats and Proteins, I suppose.

Plants use carbon dioxide from the air through photosynthesis to make carbohydrates, fats, and proteins. During photosynthesis, carbon is converted into glucose, which serves as the building block for carbohydrates. Fats and proteins are produced by further modifying glucose and incorporating other elements like nitrogen and sulfur.
The primary nutrients that yield energy are carbohydrates, proteins, and fats. Carbohydrates provide approximately 4 calories per gram, while proteins also yield about 4 calories per gram. Fats are the most energy-dense, delivering around 9 calories per gram. Alcohol can also provide energy, yielding about 7 calories per gram.
If the carbohydrate content is insufficient, the body can convert proteins and fats into glucose through gluconeogenesis. Amino acids from proteins can be transformed into glucose, while certain glycerol components from fats can also be utilized in this process. This allows the body to maintain adequate glucose levels for energy, especially during periods of fasting or low carbohydrate intake.
