Final answer:
Cells use transport proteins and glycolysis to get glucose into the cells, which is then used to release energy through cellular respiration.
Step-by-step explanation:
Cellular Respiration and Glucose Transport
When you eat food, your body breaks it down into tiny molecules called glucose. Glucose is the form of energy that is carried in your blood and taken up by each of your cells. To get the glucose into your cells, there are several parts of the cell involved:
- Transport proteins in the cell membrane called GLUT proteins assist in the facilitated diffusion of glucose into the cell.
- Glycolysis, the first step in the breakdown of glucose, takes place in the cytoplasm of the cell and does not require oxygen.
- The glucose that enters the circulatory system is taken up by cells in response to insulin, and through a series of reactions called glycolysis, some of the energy in glucose is transferred to ADP to form ATP - the usable form of energy for cells.
Overall, cellular respiration allows glucose to be broken down and used by cells to release energy.
