Molecules and Cells
This molecule from food provides cells with energy.
What is glucose?
This system brings oxygen molecules into the body from the air.
What is the respiratory system?
This condition causes the airways in the lungs to narrow, making it hard to breathe.
What is asthma?
This word describes the body’s use of molecules for energy and growth.
What is metabolism?
Doctors use this tool to help people with asthma open their airways.
What is an inhaler?
These molecules are the building blocks of proteins.
What are amino acids?
This system moves molecules like glucose and oxygen throughout the body.
What is the circulatory system?
This condition occurs when the body cannot make enough insulin.
What is diabetes?
Cells need this molecule from the air to release energy from glucose.
What is oxygen?
People with diabetes often test this to monitor their health.
What is blood glucose level?
Cells use these three molecules to stay alive and function properly.
What are oxygen, glucose, and amino acids?
This system breaks down food into smaller molecules.
What is the digestive system?
This condition happens when there are not enough healthy red blood cells to carry oxygen.
What is anemia?
This happens when the bodies systems do not receive the molecules it needs to function.
What is they cannot release energy and the body’s systems do not function properly?
Someone with anemia might feel tired because their cells are not getting enough of this molecule.
What is oxygen?
If glucose cannot enter a cell, which molecule is missing to “unlock” the cell membrane?
What is insulin?
If the respiratory system brings in oxygen and the digestive system provides glucose, what is the circulatory system’s job?
What is to transport these molecules to all the cells in the body?
An injury to this organ makes it difficult to digest food properly because it produces digestive enzymes and insulin.
What is injury to the pancreas?
When you exercise, your cells use more energy. These two molecules your cells need more of.
What are oxygen and glucose?
This daily habit helps your body get amino acids for growth and repair.
What is eating protein-rich foods like meat, beans, or eggs?
(Daily Double đź’Ą):
Explain why cells can’t use starch directly for energy.
What is starch is too large to enter cells and must be broken down into glucose first?
Explain how the three systems we learned about work together to support the metabolism.
What is the digestive system provides glucose, the respiratory system provides oxygen, and the circulatory system delivers both to cells for energy production?
(Daily Double đź’Ą):
Compare how asthma and diabetes both prevent cells from getting what they need.
What is asthma limits oxygen from entering the blood, while diabetes prevents glucose from entering the cells?
Explain how a person with diabetes can have high blood glucose levels but still have low energy.
What is because glucose is stuck in the blood and cannot enter cells to be used for energy?
If a person injures their pancreas, how could that affect their ability to maintain a healthy metabolism?
What is the pancreas helps produce enzymes and insulin, so damage can affect digestion and glucose regulation?
