What does an athlete's body need in order to be able to exercise?
molecules from different types of food getting to the cells
molecules made by the cells
molecules from food and air getting to the cells
molecules from food getting to stomach cells
Why will a person's ability to exercise be decreased if their digestive system is not working properly?
the cells need molecules from food to be broken down so they are small enough to use
the body will run out of energy because molecules from air will not combine into larger molecules for the cells
the respiratory system will have to work twice as hard to break down molecules from food
the cells will not work well because molecules from food will be too small to be used
Which molecules are needed by our cells?
oxygen, water, carbon dioxide
oxygen, carbon dioxide, amino acids
oxygen, glucose, amino acids
glucose, amino acids, carbon dioxide
Which of the following are the building blocks of proteins?
glucose
amino acids
oxygen
starch
Which two molecules are used by the cell to release energy?
oxygen and glucose
oxygen and carbon dioxide
glucose and amino acids
glucose and starch
Which of the following would indicate that a person's body is healthy enough to function at a high level?
cells are getting several different types of food molecules
the body is getting enough sleep to make energy
the lung cells have molecules from air and the stomach cells have molecules from food
the cells are getting the molecules they need from food and air
Which of the following would indicate a patient's body is not working properly?
low levels of starch in the cells
low levels of oxygen in the small intestine
low levels of glucose in the small intestine
normal levels of oxygen in the lungs
Which body system is responsible for taking in food and breaking it down?
circulatory
respiratory
digestive
nervous
Which body system is responsible for taking in oxygen and removing carbon dioxide?
circulatory
respiratory
digestive
nervous
Which body system is responsible for transporting molecules to and from cells?
circulatory
respiratory
digestive
nervous
Could a person still exercise normally if their digestive system is not working properly?
Yes, as long as they can still breathe they will get all the molecules they need to release energy.
No, oxygen molecules will not be getting broken down into molecules small enough to get inside the cells.
No, food molecules are not combining together to be large enough for cells to use.
No, molecules from food are not getting broken down small enough for cells to use.
If a person is breathing normally, which of the following could prevent the body from working normally?
not getting enough sunlight, because cells need sunlight to function
not getting enough sleep, because the body only makes energy for exercise while it sleeps
not eating enough, because cells need molecules from both food and air to work
nothing, because the body can function as long as the cells are getting oxygen
Which foods provide our bodies with starch molecules?
bread, fruits, and vegetables
meat, beans, and eggs
butter and other fats
cake and candy
Which molecules come from starches?
amino acids
fiber
glucose
water
A patient reports feeling tired all the time. The doctor determines that the patient's cells contain many glucose molecules, but are low on oxygen molecules. Does this explain why they are feeling tired?
No, the cells have everything they need
Yes, the digestive system is breaking down starch but the respiratory system may not be working properly
Yes, the respiratory system is working, but the digestive system is not combining glucose molecules
Yes, the digestive system is working, but the respiratory system is not breaking down enough oxygen
If a person has normal levels of glucose and amino acids in their cells, but low levels of oxygen molecules will they have the energy to exercise normally?
Yes, their body is working properly enough to exercise
No, the digestive system is not breaking down for molecules properly
No, the body systems are working but they need different foods; only protein can react with glucose to release energy
No, the respiratory system is not working, cells need oxygen to react with glucose in order to release energy
Which of the following molecules come from protein?
glucose
amino acids
oxygen
starch
Which foods will provide the body with the amino acids they need?
bread, fruit, vegetables
meat, beans, eggs
butter and other fats
cake and candy
Scuba divers use breathing gear to help them breathe underwater. What could happen if their breathing gear broke during a dive?
If would be difficult to swim because the cells would not be getting molecules from air
If would have no effect because the cells would have everything they need from the food the diver ate before diving
It would have no effect as long as the diver got enough sleep the night before
It would have no effect because the body does not need any molecules from air
Which molecules are needed by the body in order to release energy?
oxygen and amino acids
oxygen and carbon dioxide
oxygen and glucose
oxygen and water
Which molecule is used by the body to build proteins for growth and repair?
glucose
oxygen
amino acids
carbon dioxide
What do we call a set of interacting parts that make up a complex whole?
circuit
loop
system
apparatus
Which system of the body includes the mouth/nose, trachea, and lungs?
digestive
respiratory
circulatory
nervous
Which system of the body includes the mouth, esophagus, and small intestine?
digestive
respiratory
circulatory
nervous
Which system of the body includes the heart and blood vessels?
digestive
respiratory
circulatory
nervous
What is another name for the circulatory system?
cardiovascular
musculoskeletal
lymphatic
endocrine
What term do we use to describe the body's use of molecules for energy and growth?
circulation
metabolism
lipolysis
digestion
In which part of the cell are oxygen and glucose combined to release energy?
nucleus
cell membrane
vacuole
mitochondria
In order to get into the cells, molecules must be small enough to cross through which structure?
cell membrane
alveoli
villi
nucleus
How can asthma affect a person's ability to exercise?
their cells may not get the glucose they need
their cells may not get the oxygen they need
their cells may not get the amino acids they need
it doesn't...cells only need molecules from food to function
How can diabetes affect a person's ability to exercise?
their cells may not get the glucose they need
their cells may not get the oxygen they need
their cells may not get the amino acids they need
it doesn't...cells only need molecules from air to function
Which two molecules are chemically combined in the mitochondria of the cells in order to create energy?
oxygen and carbon dioxide
oxygen and glucose
amino acids and glucose
carbon dioxide and water
