What's the difference between starch and glucose?
Starch is a type of protein and glucose is a sugar
Starch is made up of many glucose molecules bonded together
Glucose is made up of many starch molecules bonded together
Glucose is a type of protein and starch is a sugar
Why do molecules in the small intestine seem like they are disappearing?
The molecules are getting absorbed into the blood
The molecules are returning to the stomach
The molecules are going to the large intestine
The molecules are broken down and no longer exist
What does COMPLEX CARBOHYDRATES (starch) turn into when it is chemically broken apart?
Glucose
Fatty Acids
Amino Acids
Fiber
Why are some molecules absorbed into the blood stream, but some molecules are not?
Some molecules are bigger than others.
Some molecules are liquids.
Some molecules are healthier for you.
Some molecules are smaller than others.
When you eat, what happens to the fiber in your food?
Fiber is broken down into starch molecules and absorbed
Fiber is too big to be absorbed, so it is excreted as solid waste
Fiber is broken down into glucose and absorbed
Fiber is coming together and getting bigger. Then it is absorbed.
Gas exchange is needed to supply _____________ to cells and remove __________________
carbon dioxide; oxygen
oxygen; food
oxygen; carbon dioxide
carbon dioxide; water
The air sacs that are covered with capillaries where gas exchange takes place.
Bronchi
Trachea
Oxygen
Alveoli
The exhaled air from our body consists mostly of__________
carbon dioxide
nitrous oxide
oxygen
helium
When you breathe, your lungs take in ___ and remove ___.
air/oxygen
oxygen/carbon dioxide
carbon dioxide/waste
waste/air
Why is Amaya having shortness of breath from a digestive system disease?
She is out of shape from lack of activity
Her lungs are trying to supply more oxygen to her cells for chemical reactions to take place
Her lungs are trying to bring carbon dioxide to her cells for chemical reactions to take place
The cells in her body need glucose from the lungs for chemical reactions to take place
Amaya has rapid heartbeat. How is that related to celiac disease?
Her heart is pumping blood faster to try and bring enough oxygen and carbon dioxide to her cells
Her heart is pumping blood faster to try and bring enough oxygen and starch to her cells
Her heart is pumping blood faster to try and bring enough oxygen and glucose to her cells
Her heart is pumping harder because she's out of shape from lack of activity
Our cells are constantly in need of energy. Through a chemical reaction, the cells turn _____ and _____ into a usable form of energy.
oxygen ; carbon dioxide
oxygen ; glucose
carbon dioxide ; glucose
carbon dioxide ; water
How are the digestive system and respiratory system related?
They both send important substances to the bloodstream to be carried around the body to all cells
They're not related at all
They work together to digest food
They both provide the body with oxygen for the cells
Blood is part of which system?
circulatory
respiratory
digestive
Which reactant molecule from the air is needed by all of your cells?
oxygen
carbon dioxide
fat
glucose
How does oxygen get into the blood?
it enters through the villi in the small intestine
it enters through the alveoli in the lungs
it is created during cellular respiration
Your blood is like an Amazon delivery truck. Why?
Blood brings food molecules and oxygen to cells and takes carbon dioxide and water away.
Blood delivers carbon dioxide to the cells. and takes away food.
Blood brings food molecules to the lungs and takes oxygen away from cells
Why do the cells of your body need glucose?
for energy
to excrete
to absorb carbon dioxide.
What is the name of the chemical reaction happening in all the cells of our body that burns food molecules as fuel?
absorption
cellular excretion
cellular respiration
digestion
What are the reactants in this chemical equation?
villi and alveoli
water and energy
glucose and oxygen
blood and cells
What are the products in this chemical equation?
villi and alveoli
water, carbon dioxide, and energy
glucose and oxygen
blood and cells
When a person like Amaya burns glucose, where do the product molecules of CO2 and H20 go?
out of the body through sweat
out of the body through pooping
out of the body through breathing
turned into muscle
