Where does your physical energy come from? The physical energy used to move your body comes from two primary sources, glycogen and ketone.

glycogen – 

glycogen is the stored form of glucose.

glycogen is the main source of carbohydrate that is stored in the human body. It is found mainly in muscle and the liver and is the major energy source for…

glycogen is the body’s stored form of glucose, which is sugar. glycogen is made from several connected glucose molecules and is your body’s primary and…

Glycogen is defined as a stored form of glucose in the body, primarily found in the muscles and the liver, which can be utilized as a source of energy during…

glycogen is a form of glucose that helps regulate your blood sugar levels. your eating and exercise habits play a role in determining your glycogen level

the stored form of glucose is made up of many connected glucose molecules an d is called glycogen. when the body needs a quick boost of energy or when the body

glycogen is an extensively branced glucose polymer that animals use as an energy reserve. it is the animal analog to starch.

Glycogen is a form of glucose, the main source of energy that your body stores primarily in your liver and muscles.

Glycogen is a multibranched polysaccharide of glucose that serves as a form of energy storage in animals, fungi, and bacteria.

Glycogen is the body’s primary way to store extra glucose (sugar) from carbohydrates, acting as a readily available energy reserve in the liver and muscles, like a backup fuel tank. It’s a large, branched chain of glucose molecules, crucial for maintaining stable blood sugar levels(glucose homeostasis), providing quick energy from muscles during exercise, and fueling the brain t=with its breakdown (glycogenolysis) and formation (glycogenesis) regulated by hormones like insulin and glucagon.

ketone – 

Ketones are a uniquely powerful macronutrient that can cross the blood-brain barrier and increase brain energy efficiency.

Ketone bodies are prominent fuel sources for all evolutionary domains of life. The body can use ketones as a source of energy in the absence of…

Ketones are produced when fats are broken down for energy in the body.

Ketones are produced when your body breaks down fat for energy rather than using sugar. Check for ketones if your blood sugar is over 240 or if you are sick.

Ketones are acids your body releases when it burns fat instead of glucose for energy. They fuel your brain and body when your stores of…

Ketones contain a carbonyl group

Ketones provide a quick and efficient energy source, enhancing endurance and performance.

Ketones are natural chemicals your body makes from fat for energy when sugar (glucose) isn’t available, acting as a backup fuel.

In the body (biology/metabolism)

Function: when glucose is scarce (due to low insulin, fasting, or low-carb diets), the body breaks down fat, producing ketone bodies (like beta-hydroxybutyrate) that fuel the brain and muscles.
