Molecules in the body
Name 3 molecules needed for the body to function
System that accepts oxygen
What is respiratory system?
The two molecules needed to create energy in the cell
glucose and oxygen
glucose and oxygen
All of the following are examples of metabolic conditions EXCEPT …
A. Anemia C. Diabetes
B. Asthma D. Respiration
D. Respiration
This molecule is what you get from food to release energy in your cells.
What is glucose?
This system breaks down the macromolecules from food into micro molecules for our cells to use.
What is digestive system?
What are the two other molecules created in the cell when glucose and oxygen make energy
carbon dioxide and water
If someone is eating healthy foods including starch, is NOT taking in healthy amounts of oxygen, would they be able to exercise? Why or why not?
no, the body needs both oxygen and glucose to make energy.
Which of the following molecules is used by the body for growth and repair
a.Amino Acids. c.Oxygen
b.Glucose d. Starch
This molecule comes from meat, fish, beans, eggs, etc.
protein
This system transports oxygen and glucose into the cell
What is circulatory system?
What are the inputs and outputs of cellular respiration?
Inputs: glucose + oxygen
Outputs: water, CO2, energy
Who would have more energy to run? Someone who ate starch for breakfast or someone who ate protein?
Starch
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?
a.Yes, the body only works when cells get molecules from food and molecules from air.
b. No, the body only works when cells are getting molecules from different types of food.
c. No, the body only works when the lungs get molecules from air, and the stomach gets molecules from food.
d.No, the body works as long as cells are making all the molecules they need.
a.Yes, the body only works when cells get molecules from food and molecules from air.
This molecule is broken down from protein into
When this system is not working properly it can lead to asthma
what is respiratory?
Which meal will provide the molecules needed to create energy in the cells:
Rice which is made of starch
OR
Steak which is made of protein
Rice
Explain the reason an athletes takes in more oxygen in their cells
to produce more energy for exercise
The space exploration program has hired you for advice on how to keep astronauts healthy in the space shuttle. How can the program’s doctors make sure the astronauts’ bodies work well enough to exercise in space?
a.The doctors could make sure that the astronauts’ bodies can make enough energy by getting enough sleep.
b.The doctors could make sure the astronauts’ stomachs are getting the molecules they need from food and air.
c.The doctors could make sure the astronauts’ cells are getting the molecules they need from food and air.
d.The doctors could make sure the astronauts’ cells are getting different types of molecules from food.
c. The doctors could make sure the astronauts’ cells are getting the molecules they need from food and air.
Which two molecules are not broken down that causes health issues in people living with pancreas injury?
What is protein and starch?
Anemia affects this system by preventing enough oxygen to be carried to the cell
What is Circulatory?
Doctors tested a patient to find out what molecules were in her cells. Her cells contained normal levels of oxygen molecules and low levels of glucose, would this patient be able to exercise? Why or why not?
No her body needs oxygen and glucose to make energy
In order for our cells to ______ and _______, the amino acids turn back into ___________ molecules in the cells.
Repair and Grow, Protein
Some types of syrup are almost entirely made of glucose molecules. If a person ate some syrup like this, what would happen to her ability to exercise?
a. It would be harder for her to exercise because her digestive system would need to use more enzymes to combine the glucose molecules together.
b. It would be easier for her to exercise because glucose moves through the circulatory system faster than other food molecules usually do.
c. Nothing would happen to her ability to exercise, but her respiratory system would not work as hard, since glucose has more energy than oxygen molecules.
d. Nothing would happen to her ability to exercise, but her digestive system would not work as hard, since glucose is already small enough to get to her cells.
d. Nothing would happen to her ability to exercise, but her digestive system would not work as hard, since glucose is already small enough to get to her cells.
