Eat something. Carbohydrates are the first to be used in the citric acid cycle.
The process in which autotrophs use light energy to make carbohydrates is called photosynthesis. Chemosynthesis is the process by which some organisms use chemical energy to produce carbohydrates.
Complex carbohydrates contain longer chains of sugar molecules which require more time and energy for the body to break down into usable energy compared to simple carbohydrates, which are already in a more easily digestible form. The process of breaking down complex carbohydrates involves more enzymatic activity and takes longer, leading to a higher energy expenditure.
Carbohydrates are digested to give us energy to make us able to do daily activities.
Carbohydrates will give you energy with which to do your exercise, but the muscle itself is made from protein.

photosynthesis
Carbohydrates take the form of sugars, oligosaccharides, starches and fibres and are one of the three major macro-nutrients which supply the body with energy (fat and protein being the others). There is now good evidence that at least 55% of our daily calories should come from carbohydrates. You need carbohydrates to make glucose. if you don't have carbohydrates you get hungry

photosynthesis
First, energy from the sun is used to combine CO2 and water to make carbohydrates. The carbohydrates have stored energy that is released when the carbohydrates are broken down. When animals eat the plant and break down the carbohydrates, they receive energy. In turn, carnivores that eat those animals receive energy from the fats and proteins in their prey.
because sugar is in the simple carbs and isn't in the complex carbs therefor simple carbs make you more tired after the energy burst is gone because the sugar wears off faster
