What is the purpose of cellular respiration?
To release energy for cells.
Which body system brings in oxygen from the air?
Respiratory system.
What does starch break down into?
Glucose.
What is the definition of alveoli?
Tiny air sacs in the lungs where gas exchange occurs.
What is anemia?
A condition where the blood has a low number of red blood cells, reducing oxygen delivery.
Where does cellular respiration take place in the cell?
In the mitochondria.
What is the function of the circulatory system?
To transport glucose, oxygen, and amino acids to cells.
What does protein break down into?
Amino Acids
What is metabolism?
All the chemical reactions in the body that provide energy and build molecules.
What are the symptoms of asthma?
Difficulty breathing, wheezing, and reduced oxygen intake.
What two molecules are required for cellular respiration?
Glucose and oxygen.
Name two key organs in the digestive system.
Stomach and small intestine.
What structure in the small intestine absorbs glucose?
Villi
What is the role of proteins in the body?
Proteins are used for growth and repair of cells.
How does diabetes affect the body?
It disrupts the regulation of glucose in the blood.
What are the waste products of cellular respiration?
Carbon dioxide and water.
How do body systems work together to support cellular respiration?
Digestive provides glucose, respiratory provides oxygen, circulatory delivers both.
Which molecule from the air is small enough to enter cells directly?
Oxygen.
Proteins are used for growth and repair of cells.
A process in which atoms are rearranged to create new substances.
What happens when the pancreas is injured?
Insulin production decreases, affecting glucose regulation.
How does the energy released from cellular respiration help the body?
It powers cell functions like movement, repair, and growth.
What would happen if the circulatory system stopped working?
Cells would not receive glucose or oxygen, stopping energy production.
How do amino acids help the body after they enter the bloodstream?
They are used to build and repair body tissues (proteins).
What is the function of the mitochondria?
The mitochondria produce energy for the cell through cellular respiration.
Why would an athlete with anemia struggle during exercise?
Anemia reduces red blood cells, so less oxygen is delivered to the muscles, causing fatigue.
