Can I Exercise?
If a patients cells contain normal levels of oxygen and glucose molecules, but no starch molecules. Will this patient be able to exercise normally?
Yes, because glucose and oxygen molecules can react together to release energy.
The human body only works properly when cells are getting molecules from food and molecules from air.
True
Starch gets broken into glucose or amino acids
glucose
The body system that helps with the breakdown of proteins and starch
The body's use of molecules and energy for growth
Metabolism
Why would it be a problem to exercise when there is an issue with your respiratory system?
The cells will not work well when they have low levels of oxygen.
Asthma makes it difficult for someone to breathe enough air. This will also make it difficult for someone to exercise.
True, because a person with asthma needs enough molecules from air to exercise.
Proteins come from? Eggs and Dairy OR Rice and Bread
Eggs and Dairy
The body system that helps molecules reach the cells within our bodies
Circulatory System
Molecules that are the building blocks of proteins
Amino Acids
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
A patient shows that her cells contain normal levels of oxygen molecules, low levels of amino acid molecules,and low levels of glucose molecules. The patient can exercise with no problem at all!
False! The patient cannot exercise normally because her cells need glucose to react with oxygen to release enough energy to exercise.
The job of the digestive system is to? Breakdown foods OR get molecules to the cells?
Breakdown foods
The body system that works together to move oxygen throughout the body and clean out waste gases like carbon dioxide
Respiratory System
Molecule that organisms get from the air or water around them and use to release energy
Oxygen
If a patient eats a couple of grapes (these contain glucose molecules) will it change their ability to exercise?
Nothing would really happen with their ability to exercise.
A patient who has been eating healthy foods says she can still exercise without any problems even though her respiratory system is not working 100%.
False. Her cells do not have enough oxygen to react with glucose and release energy.
A patient has been feeling very tired. His test results showed that his cells contained normal levels of oxygen and low levels of glucose. Which body system is not working as it should be based on the results of the test? Respiratory or Digestive?
Digestive system is not breaking down starch molecules into glucose for his cells.
Which body systems should doctors test in order to find out whether someone's cells are getting enough oxygen and glucose and why?
The digestive should be tested to make sure starch is being broken down into glucose. The respiratory system should be checked to see if there is enough oxygen being taken in from the air.

Melanie is lactose intolerance this is a problem with her digestive system. However she was really hungry and ate a cheese stick. Now she is having trouble running laps during her soccer training, why?
Because her cells do not have the molecules she needs from food only the molecules need from air.
After running tests your mouth which is part of your digestive system shows high levels of starch. Your small intestine which is also part of your digestive system shows low levels of glucose. Your lungs which are part of the respiratory show normal levels of oxygen. You believe you can exercise well because your body is working properly.
False! because the digestive system is not breaking down molecules from food into glucose
Blue team playing in high altitude (mountains) with less oxygen. Red team playing at sea level (on the beach) normal levels of oxygen. Blue team's lunch consists of starch and protein. Red team's lunch consists of just starch. Which team probably did better and why?
The Red team because their cells released energy from oxygen reacting with glucose, which was broken down from starch in the digestive system. (cellular respiration)
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
The process of how cells use glucose to release energy
