Osmosis
The movement of water molecules through a semi-permeable membrane.
(What is osmosis?)
The passive movement of molecules from an area of high concentration to low concentration.
(What is diffusion?)
Proteins that speed up chemical reactions in the body.
(What are enzymes?)
Enzymes work best at a specific ______ and ______.
(What are pH, temperature?)
Osmosis moves water from areas of ______ concentration to areas of ______ concentration.
(What are high, low?)
Diffusion stops when molecules reach this state.
(What is equilibrium?)
The substance an enzyme acts on.
(What is a substrate?)
A condition where an enzyme loses its shape and cannot function.
(What is denaturation?)
This type of solution causes a cell to swell as water enters.
(What is hypotonic?)
The gas that enters cells during diffusion for respiration.
(What is oxygen?)
The specific location on an enzyme where a substrate binds.
(What is the active site?)
A high fever can denature enzymes because of this factor.
(What is high temperature?)
This term describes when the concentration of solutes is the same inside and outside the cell.
(What is isotonic?)
Diffusion is faster in this state of matter.
(What is gas?)
Enzymes function as these types of biological molecules.
(What are catalysts?)
Too much acidity or alkalinity can affect this enzyme property.
(What is pH sensitivity?)
Water moves into a plant cell’s vacuole, causing the cell to become stiff.
(What is osmosis?)
Movement of small, non-polar molecules (like oxygen and carbon dioxide) across the cell membrane without the help of any proteins.
(What is Simple Diffusion?)
After a reaction, enzymes remain ______ and can be used again.
(What is unchanged?)
The term for the products released after the enzyme works on the substrate.
(What are end products?)
