M'Kenna
The name of the medical condition M’Kenna is diagnosed with after her endoscopy.
What is Celiac Disease?
The process of breaking down large food molecules into smaller ones.
What is digestion?
The two things cells need to perform a chemical reaction to release energy.
What are glucose and oxygen?
This system acts like a "highway" to transport glucose and oxyge.n to every cell
What is the circulatory system?
These are the two "inputs" or reactants that a cell needs to perform this energy-releasing reaction.
What are glucose (sugar) and oxygen?
This organ in M'Kenna's digestive system looked different from a healthy one in the simulation.
What is the small intestine?
This happens to small molecules like glucose once they leave the small intestine.
What is absorption (into the blood)?
This is the main "goal" of metabolic reactions in the body's cells.
What is releasing energy?
This system brings oxygen into the body and removes carbon dioxide.
What is the respiratory system?
This is the specific organelle, or part of the cell, where cellular respiration takes place.
What is the mitochondria?
he microscopic, finger-like projections in the small intestine that were "flattened" in M’Kenna.
What are villi?
Starch is a large molecule that breaks down into this smaller sugar molecule.
What is glucose?
The waste gas produced when cells use glucose for energy.
What is carbon dioxide (CO2)
If a person's villi are flat, this system cannot get the "fuel" it needs to transport to the rest of the body.
What is the digestive system?
Besides energy, these are the two "outputs" or waste products created during the reaction.
What are carbon dioxide (CO2) and water (H2O)
This large molecule never gets digested or absorbed in a healthy person or M’Kenna.
What is fiber?
This organ is responsible for absorbing water and moving waste out of the body.
What is the large intestine?
This animal "phenomenon" is often used to show how the body uses stored fat for energy when it can't eat.
What is hibernation (e.g., in bears)?
When you exercise, these two systems speed up to provide more "fuel" and "air" to your muscles.
What are the respiratory and circulatory systems?
This is the name of the usable form of energy that cells create during this process (often abbreviated as three letters).
What is ATP?
The reason M’Kenna was losing weight even though she was eating
What is because her body was not absorbing nutrients (like glucose) into her bloodstream?
Two things that must happen for a large food molecule to actually "enter" the body's systems.
What are breakdown (chemical reaction) and absorption?
The specific part of the cell where these energy-releasing reactions happen.
What is the mitochondria?
This is the term for the body's ability to maintain a stable internal environment.
What is homeostasis?
During exercise, your breathing and heart rate increase to get more of this specific gas to your cells faster.
What is oxygen?
