(Blank)
Fill in the blank: A functioning body has _________. From both food and air.
Molecules
What system transports different molecules around the body?
The Circulatory System
What system takes oxygen molecules in the body and carbon dioxide out of the body.
The Respiratory System.
What system breaks down food?
The Digestive System.
Fill in the blank: Cells can only use molecules that are _____ enough to enter a cell.
Small
What are the two molecules needed for cellular resperation?
Glucose and oxygen
What is asthma do to our body?
It tightens our capillaries so smaller amount of oxygen can get through our bodies.
What does diabetes do our bodies?
Diabetes is when there's not enough insulin in our bodies which makes it harder for molecules to enter our cells.
Fill in the blank: In order to release energy, cells need both _______ and oxygen molecules.
Glucose
What molecule does starch break down into?
Glucose
What are 3 molecules the go through the circulatory system.
1. Glucose
2. Oxygen
3. Amino Acids
Why is it important for starch and protein to break down?
So they'll be small enough to fit into cells.
Fill in the blank: Inside the cell, the atoms that make up glucose and oxygen can be rearranged to make different molecules. This chemical reaction is called ___________________ and release energy.
Cellular Respiration
What is the best way to get energy?
First eating starch and exercising or breathing hard.
What molecule does protein break down into?
Amino Acids
Where do amino acids turn into back into protein molecules?
In the mitochondria.
Fill in the blank: Cells can grow and repair themselves by combining amino acid molecules to form larger _______ molecules. This growth and repair requires energy release from cellular respiration.
Protein
How much glucose and oxygen molecules are needed for cellular respiration at minimum?
1 glucose molecules
6 oxygen molecules
What does the mitochondria do for cellular respiration?
It turns glucose and oxygen into energy.
How does exercising affect the respiratory system?
More oxygen molecules come in through the respiratory system.
