Sugar molecules are primarily broken down for energy through processes like glycolysis and cellular respiration. When the body has excess sugar, it can convert it into glycogen for short-term storage in the liver and muscles. If there is still excess sugar after glycogen stores are full, it can be converted into fats for long-term energy storage. Thus, sugars can be both utilized for immediate energy and stored for future use, primarily as glycogen or fat.
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.
Carbohydrate molecules do not form enzymes. Enzymes are typically proteins that act as biological catalysts to speed up chemical reactions in living organisms. Carbohydrates are organic compounds that function primarily as a source of energy or structural components in cells.

Three important organic molecules in life are carbohydrates, proteins, and lipids. Carbohydrates are essential for energy storage and cellular structure, proteins are involved in various cellular functions such as enzyme activity and structural support, and lipids are important for energy storage and forming cellular membranes.
False. Carbohydrates are typically the body's first choice for energy because they are quickly broken down into glucose. Proteins are usually used as a secondary source of energy when carbohydrates are not available.
Carbohydrates, fats, and proteins are broken down to make ATP. Carbohydrates are most often broken down to make ATP because they are the body's preferred source of energy due to their quick and efficient conversion into ATP through glycolysis and the citric acid cycle.
Your body cannot use starch because it is a complex carbohydrate. It must be broken down into shorter carbohydrate strings before being converted into energy

Starch is a carbohydrate, providing short and middle-term energy but few proteins.

They are broken down into simpler molecules by the digestive system so they can be absorbed into the bloodstream.
The energy needed for metabolism comes from the breakdown of molecules such as glucose, fats, and proteins. During metabolism, these molecules are broken down to release energy in the form of ATP, which cells can use for various cellular processes.
