Vocabulary
The body's use of molecules and energy for growth
Metabolism
The body system that helps with the breakdown of proteins and starch
Digestive System
Where do cells get the molecules they need?
food and air
A patient's respiratory system is not working even though they ARE eating healthy foods. Can this patient still exercise normally?
No, her cells do not have enough oxygen to react with glucose and release energy
The two molecules affected by the digestive system
Amino acids and glucose
Molecules that are the building blocks of proteins
amino acids
The body system that helps molecules reach the cells within our bodies
Circulatory System
How can doctors make sure our body is working well enough to exercise?
Monitor that cells are getting enough molecules from the food they eat and air they breathe
When someone has NORMAL levels of OXYGEN but LOW levels of GLUCOSE what system system is working properly and what system is not?
The respiratory system is working, but the digestive system is not breaking down starch molecules into glucose for the cells
The job of the digestive system is to?
Break down proteins and starch into smaller molecules that can be used by the cells in our bodies
Molecule that organisms get from the air or water around them and use to release energy
oxygen
The body system that works together to move oxygen throughout the body and clean out waste gases like carbon dioxide
Respiratory System
Doctors tested a patient and found that his cells contained normal levels of oxygen and glucose molecules, and no starch molecules. Will this patient be able to exercise normally?
Yes because glucose and oxygen molecules can react together to release energy for the body to function
Would asthma make it difficult for someone to exercise if it causes difficulty breathing?
Yes, it will be difficult for a person with asthma to exercise because cells need molecules from air.
What is an example of foods with protein?
meat, poultry, fish, eggs, dairy
A group of atoms joined together in a particular way
molecule
A student thinks that the human body only works properly when cells are getting molecules from food and molecules from air. Is the student correct?
Yes, the body only works when cells get molecules from food and molecules from air.
The molecule that is most affected by this body system?
oxygen
What is an example of foods with starch?
Potatoes, bread, rice, pasta, and cereals
The process of how cells use glucose to release energy
cellular respiration
How can doctors make sure someone's bodies work well enough to exercise anywhere other than their normal environment?
By monitoring cells are receiving the necessary molecules needed from food and air
Why would it be hard to exercise when you have a digestion problem and your body is not able to digest enough food.
Because cells would not have enough molecules from food.
What would happen to someone who ate a candy with several glucose molecules
Nothing would really happen with their ability to exercise.
Grape juice contains lots of glucose in it. Since the glucose molecule is directly found in grape juice would the digestive system have to work hard to break it down?
No, since the molecule is already broken down it is small enough to get to the cells that need it
