This is the organ system that pumps blood through our body.
What is the circulatory system?
An area with less solutes.
What is hypotonic?
This is the chemical that an enzyme acts upon.
What is a substrate?
This is the name for the body system that is a network of glands that release hormones.
What is the endocrine system?
Multiple small sugars, attached to one another, make up this kind of molecule.
What is a starch?
This is the organ system that takes in oxygen gas, and releases carbon dioxide and water.
What is the respiratory system?
When molecules spread out along the concentration gradient.
What is diffusion?
This is the part of the enzyme where the substrate binds.
What is the active site?
This is the hormone that regulates our sleep cycles by making us tired.
What is melatonin?
A chemical that changes color to show the presence of another chemical that cannot be seen.

This organ system primarily uses white blood cells to destroy unwanted materials that enter our bodies.
What is the immune system?
Molecules with this property can easily pass through a cell membrane.
What is being small?
This is the enzyme in our stomach that digests proteins.
What is pepsin?
This is the hormone that increases our blood sugar.
What is glucagon?
This organelle surrounds every cell.
What is the cell membrane?
This body system uses hormones to regulate growth, sleep, and metabolism.
What is the endocrine system?
This chemical was used as a starch indicator in the diffusion and osmosis lab.
What is Lugol's Iodine solution?
This is the enzyme that breaks down Hydrogen Peroxide.
What is catalase?
This hormone is our 'reward system' that tells us when we've done something good.
What is dopamine?
This hormone stimulates contractions, as part of a positive feedback loop during childbirth.
What is oxytocin?
