test Q.
An athlete thinks that she can exercise as long as she eats different types of food because her body just needs different types of food molecules to work properly. Is the athlete correct?
No, all cells need molecules from food and molecules from air to work properly.
Marisol has been chewing and swallowing her food, but her digestive system is not doing what it usually does. Why is this a problem for her ability to exercise?
Her cells will not work well because molecules from her food are not being broken down small enough to get to her cells.
Doctors tested a patient to find out what molecules were in her cells. Her cells contained normal levels of amino acids, normal levels of oxygen molecules, and low levels of glucose molecules. Will this patient be able to exercise normally?
No, her cells need glucose to react with oxygen to release energy.
An ocean scientist plans to spend several days underwater in a submarine. Doctors on land will monitor her body to make sure she is healthy during her trip. What is one way doctors will be able to tell whether her body is healthy enough to do all her tasks while she is in the submarine?
The doctors could see if her cells are getting the molecules they need from food and air.
A patient has been eating healthy foods, but his digestive system is not doing what it usually does. Can this patient still exercise normally?
No, molecules from food are not getting broken down small enough to get inside his cells.
If a person is breathing normally, which of the following could prevent him from using his body to exercise normally?
Not eating enough food, because cells need molecules from both food and air to work
Raoul ate a meal of oats before seeing his doctor. Oats are made of mostly starch molecules. Raoul feels tired, so his doctor gave him a test and found that Raoul’s cells contained glucose molecules, but they did not contain enough oxygen molecules. Does this explain why Raoul feels tired?
Yes, his digestive system is breaking down starch molecules, but his respiratory system may not be working properly.
Doctors tested a patient to find out what molecules were in his cells. His cells contained normal levels of glucose molecules and amino acid molecules, and low levels of oxygen molecules. Will this patient be able to exercise normally?
No, his respiratory system is not working; his cells need oxygen to react with glucose, which releases energy.
Rico, a scuba diver, uses breathing gear to help him breathe air underwater. He always gets enough sleep and eats a good breakfast before a dive. What could happen if his breathing gear broke during a dive and he could not breathe as much air as usual?
It would be difficult to swim, because his cells cannot work without molecules from air.
Two teams of scientists hiked 10 kilometers to different study sites. Before their hike, the Valley team ate a lunch of mostly protein. The Mountain team ate a lunch of a mix of starch and protein, but hiked at high altitude, where there is much less oxygen. Which team probably had an easier time hiking?
Neither team had an easy time hiking; the Valley team’s cells needed more glucose from broken-down starch for a reaction, and the Mountain team’s cells needed more oxygen from air.
What is cellular respiration?
The combination of oxygen and glucose to make energy.
What molecules are needed to make energy?
oxygen and glucose
If one body system is not working right, will the person have simular experience?
no every system needs to work properly.
What molecules do you need in your daily life?
Starch, oxygen, and protein.
what is the pathway of glucose through the body?
First it goes into the digestive system, then into the circulatory system, and to the cells in the body.
What is the pathway of oxygen in the body?
It first goes into the resperatory, then in the circulatory system, and finish in the cells of the body.
where do you get oxygen?
from air
where do you get starch?
From food.
where do you get protein?
From food.
What are the 5 systems in a healthy body?
The circulatory, resperatory, digestive, systems and cells in the body. Additionally, glucose storage.
how does cellular respiration happen?
The oxygen and glucose combine and form energy.
what are the 4 conditions we learned about?
Anemia, Asthma, Diabetes, and the Pancreas injury.
What is asthma?
It is when your lungs close and you can't breath.
What is diabetes?
having low insulin.
What is a pancreas injury?
It is when you have trouble digesting.
