Molecules
Cells in the body need these three types of molecules.
What are oxygen, glucose, and amino acids?
This body system takes in food and breaks it down into molecules that can be used by the cells in the body.
What is the digestive system?
Cellular respiration is a chemical reaction between what two reactants?
What are oxygen and glucose?
A set of interacting parts forming a complex whole.
What is a system?
This is a condition where the body has a low number of red blood cells, which reduces the amount of oxygen delivered to cells.
What is anemia?
In the digestive system, these are broken down into amino acids.
What are proteins?
This body system transports molecules to and from all cells of the body.
What is the circulatory system?
Cellular respiration results in the production of this - the ability to make things move or change.
What is energy?
A group of atoms joined together in a particular way.
What is a molecule?
What is asthma?
Hemoglobin is a type of protein that carries and delivers this type of molecule to all the cells in the body.
This body system takes in oxygen through the nose or mouth and into the lungs.
What is the respiratory system?
Cellular respiration is a chemical reaction that occurs in here in cells?
What is in the mitochondria?
A proposed answer to a question about the natural world that is supported by evidence and reasoning.
What is a scientific argument?
Someone who has a problem with this body part (organ) might have difficulty breaking down protein and starch into smaller molecules.
What is the pancreas?
Proteins are too big to enter the cell, but these molecules are used to build the proteins that the body needs to repair itself and grow.
What are amino acids?
This body system carries carbon dioxide away from the cells to the lungs.
What is the circulatory system?
This molecule is small enough to enter the cell without needing to be broken down into a smaller molecule. It is one of the reactants in cellular respiration.
What is oxygen?
A process in which atoms rearrange to form new substances.
What is a chemical reaction?
This medical condition can cause someone to have very high amounts of glucose in the blood.
What is diabetes?
Foods like white rice contain a lot of this - a type of energy storage molecule made of many glucose molecules connected together.
What is starch?
This molecule is made in the pancreas, which is part of the digestive system. It is carried throughout the body by the circulatory system. It's job is to signal cell to take in glucose.
What is insulin?
Energy that is produced during cellular respiration might be used to make these large molecules that are used to grow and repair the body.
What are proteins?
This is the name for all of the processes that involve digestion, respiration, and cellular respiration to provide the oxygen and nutrients cells need.
What is metabolism?
A person with the following test results might have this condition.
O2 intake in the lungs: Normal
O2 level in the circulatory system: Low
O2 molecules absorbed by the cells: Low
Glucose absorbed by the cells: Normal
What is anemia?
