Question

What happens to converted body fuels after foods have been eaten?

1) They are stored in the liver
2) They are converted into energy
3) They are excreted as waste
4) They are used to build muscles

Answer 1

Converted body fuels from the food we eat can either be immediately used for energy or stored. Excess glucose is stored as glycogen in the liver and muscles, while excess fats are stored as triglycerides in adipose tissue.

Step-by-step explanation:

When foods are eaten, the body converts the nutrients from these foods into various forms. If energy is exerted shortly after eating, dietary fats and sugars are processed and used immediately for energy. However, if there is no immediate demand for energy, or if an excess of nutrients exists, excess glucose is stored as glycogen in the liver and muscle cells. Any excess dietary fat is stored as triglycerides in adipose tissues. These mechanisms make it possible to store energy that can be used later, ensuring that organs like the brain receive a continuous supply of glucose, even when food intake is not constant.

Different components are handled in various ways as follows:

• Excess dietary fats and sugars may be directly used for energy if needed immediately.
• Excess glucose is stored as glycogen in the liver and muscle cells for future energy demands.
• Excess dietary fats are stored as triglycerides in adipose tissue to be used when the body requires energy during fasting or starvation.

Therefore, converted body fuels after foods have been eaten can be both, directly used for energy and stored for future use.
