Question

Where does your body get the sugars it needs to get energy to power its cells?

a. From proteins in the diet.
b. From the atmosphere.
c. From the breakdown of carbohydrates in food.
d. From sunlight.

Answer 1

The stomach and small intestines absorb the glucose and then release it into the bloodstream. Once in the bloodstream, glucose can be used immediately for energy or stored in our bodies, to be used later. However, our bodies need insulin in order to use or store glucose for energy.

Answer 2

Your body obtains the sugar it needs for energy primarily from the breakdown of carbohydrates in food, which are digested into simpler sugars like glucose. This glucose is used to produce ATP, essential for cellular function. In the absence of carbohydrates, glucose can also come from stored glycogen or other substrates.

Step-by-step explanation:

Your body gets the sugars it needs to power its cells primarily from the breakdown of carbohydrates in food. When you consume foods rich in carbohydrates, such as bread, rice, fruits, and vegetables, your body breaks them down into simpler sugars like glucose. This glucose is then absorbed into the bloodstream and transported to your cells, where it is used to produce ATP (adenosine triphosphate), the energy currency of the cell. Without this process, your cells would not be able to function properly, as ATP is required for various cellular activities.

When dietary carbohydrates are not available, your body can also mobilize stored glycogen from the liver and skeletal muscles or convert other substrates into glucose. This ensures a continuous supply of glucose to meet the body's energy demands. Additionally, glucose is the product of photosynthesis in plants, which they use as an energy source. Animals, including humans, must consume carbohydrates to obtain this vital sugar. The process by which cells convert glucose into usable energy is known as cellular respiration.
