Molecules
A essential molecule for humans that is found in air or water.
What is oxygen?
This system takes in oxygen from the air.
What is the respiratory system?
A molecule that organisms get from the air or water around them and use to release energy.
What is oxygen?
The chemical reaction in cells that releases energy.
What is cellular respiration?
A molecule that comes from starch and can get into cells of the body.
What is glucose?
This systems breaks down food.
What is the digestive system?
A molecule that organisms can use to release energy, and that is made of carbon, hydrogen, and oxygen atoms.
What is glucose?
a possible answer to a question
What is a claim?
A molecule that comes from protein.
What are amino acids?
This system transfers all the important molecules to the cells of the body.
What is the circulatory system?
The ability to make things move or change.
What is energy?
These three molecules can be taken in by cells.
What are glucose, oxygen and amino acids?
These TWO molecules are needed for the cells to make energy.
What is glucose and oxygen?
If the respiratory system is not working properly this system also stops working properly.
What is the circulatory system?
A group of atoms joined together in a particular way
Are these results normal for a small intestine?
Glucose molecules: normal
Oxygen molecules: none
Starch: normal
What is YES (because oxygen does not enter the body through the digestive system)
This molecule is needed to repair and grow the body.
What are amino acids?
Describe how all three systems in the body work together to get molecules to the cells.
What is the respiratory system brings in oxygen, the digestive system breaks down protein and starch, and the circulatory system moves the molecules from the systems to the cells.
The body’s use of molecules for energy and growth.
What is metabolism?
It would be harder to exercise in a _____ altitude because _______.
What are higher altitude because there is less oxygen in the air?
