The journey of a cheese sandwich - how do you explain how cells use food using the big idea of partilces?????!!!!! HELP!!!! i hate these stupid assessments!!!!
Think what happens to the starch, sugar, and protein particles in the sandwich as they are digested, absorbed, into blood, then into individual cells.
I think its because the food gets to its smallest state so it can be absorbed but not sure LOL
Iam 5 years late answering this question
I understand that assessments can be frustrating, but don't worry, I'm here to help you understand how cells use food using the concept of particles. Let's break it down step by step:
1. Digestion: When you eat a cheese sandwich, your digestive system breaks it down into smaller particles through mechanical and chemical processes. Chewing mechanically breaks down the sandwich into smaller pieces, while enzymes in your saliva begin to chemically break down the starches present.
2. Absorption: Once the sandwich is broken down into smaller particles, those particles are absorbed into your bloodstream through the walls of your small intestine. This allows them to be transported to different parts of your body.
3. Transport: The blood carries the particles of the sandwich, including nutrients like carbohydrates, proteins, and fats, to the cells throughout your body. This transportation happens through the circulatory system.
4. Cellular Uptake: At the cellular level, each individual cell takes up the necessary particles from the blood to carry out its functions. This uptake of particles, such as glucose for energy or amino acids for protein synthesis, happens through specific structures in the cell membrane called transport proteins.
5. Cellular Respiration: Once inside the cell, the particles are broken down through a process called cellular respiration. This releases their stored energy, primarily in the form of ATP (adenosine triphosphate), which is the main energy currency of cells.
In summary, cells use food particles by first digesting the food into smaller particles, which are then absorbed into the bloodstream for transport to different parts of the body. Once inside the cells, the particles are taken up to provide energy and essential molecules through cellular respiration.
Remember, understanding the underlying concepts is key to answering assessment questions effectively.
