Which of these activities would use the most energy?
Playing video games
Eating your favorite chips
Running a mile
Watching Outer Banks
If you need more energy, how does the amount of cellular respiration change?
Cellular respiration increases
Cellular respiration decreases
Cellular respiration remains the same
Which of the following is part of the circulatory system?
Small intestine
Lungs
Blood
Stomach
What is this and what is its function?
Alveoli; absorbs oxygen/carbon dioxide
Alveoli; absorbs food molecules
Villi; absorbs oxygen/carbon dioxide
Villi; absorbs food molecules
What reactants are needed to burn food? More than one answer
Carbon dioxide
Oxygen
Glucose
Water
Energy
What products are created when food is burned? More than one answer
Carbon dioxide
Oxygen
Glucose
Water
Energy
How do carbon dioxide and water vapor leave your body?
Through our stomach
Through your poop
We exhale them
We inhale them
How does oxygen enter the blood?
We inhale oxygen and absorb it through the alveoli into the blood
We inhale oxygen and absorb it through the villi into the blood
We exhale oxygen and it moves from the cells to the blood
We inhale it
How do food molecules enter the blood?
We inhale glucose and absorb it through the alveoli into the blood
We exhale glucose and it moves from the cells to the blood
We eat them
We take in glucose through our food and absorb it through the villi into the blood
Define cellular respiration.
A chemical reaction that rearranges carbon dioxide molecules
A chemical reaction that occurs in cells and provides them with energy
A chemical reaction that splits oxygen to produce glucose
A physical change that provides energy to cells
After cellular respiration, how do carbon dioxide and water leave our cells?
CO2 and H2O leave the cells as excrement
CO2 and H2O leave the cells as sweat
All CO2 and H2O are produced in the lungs and exhaled
CO2 and H2O are carried by the blood back to the lungs and then exhaled
Where does cellular respiration occur?
Muscle cells
Brain cells
Stomach cells
All cells
How does the circulatory system support cellular respiration?
The circulatory system uses our breath to move oxygen and carbon dioxide to the cells for energy
The circulatory system uses our nerves to move just oxygen to the cells for energy
The circulatory system pumps the blood that moves oxygen and glucose to the cells for energy
During hibernation, chipmunks do not eat anything. Where do they get the energy needed to survive?
Chipmunks use their muscles in cellular respiration
Chipmunks use their fat reserves in cellular respiration
Chipmunks inhale glucose from the air and use it in cellular respiration
Chipmunks store their food in their cheeks
