Carbohydrates, lipids, and proteins are compounds that store energy within the cell. Lipids form the majority of the cell membrane, providing structure and serving as a barrier to the external environment. Proteins are essential for various cellular functions and make up a significant portion of the cell's structure and machinery.
A carbohydrate is a complex molecule of carbon, hydrogen, and oxygen found in all living organisms. These molecules store energy. All heterotrophs need carbohydrates for the energy they need to survive. Autotrophs make carbohydrates through photosynthesis or other processes.
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.
Carbohydrates will give you energy with which to do your exercise, but the muscle itself is made from protein.
Carbohydrates are digested to give us energy to make us able to do daily activities.

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.
Muscle cells use triglycerides for energy instead of carbohydrates because triglycerides make energy for storage, insulation, and organ protection
We need protein to form the main structural parts of the body cells, we also need it for growth and repair. We need carbs for energy(they are the easiest sorce), we need fats also for their richness in energy, they are also part of cell membranes and important in nerve tissues.
by using light energy to make carbohydrates
Plants use light as their source of energy to make carbohydrates such as sugars.
