Molecules
These are the building blocks that make up all things.
What are molecules?
This body system breaks down food into smaller molecules.
What is the digestive system?
All living things are made up of these.
What are cells?
This is what your body needs to move and grow.
What is energy?
This molecule is a type of sugar that cells use for energy.
What is glucose?
This body system brings oxygen into the body.
What is the respiratory system?
This is the smallest unit of life.
What is a cell?
This molecule is found in food and is used by cells to release energy.
What is glucose?
Cells get this molecule from the air to help release energy.
What is oxygen?
This body system transports molecules throughout the body using blood.
What is the circulatory system?
These need molecules from food and air to do their jobs.
What are cells?
Muscles need this to contract and help your body move.
What is energy?
These molecules help the body build and repair cells.
What are amino acids?
These three body systems work together to get food molecules and oxygen to cells.
What are the digestive, respiratory, and circulatory systems?
These are the tiny structures inside cells that perform different jobs.
What are organelles?
This process allows cells to release energy from glucose using oxygen.
What is cellular respiration?
Glucose, amino acids, and oxygen are all examples of these substances that cells need to function.
What are molecules?
If this body system stopped working properly, cells might not receive enough oxygen to release energy.
What is the respiratory system?
What two molecules do cells use to release energy?
What are glucose and oxygen?
What two molecules does cellular respiration need to release energy?
What are glucose and oxygen?
