The following document is a running list of vocabulary terms for the
Carbohydrate, Lipid and Protein unit for Biology. The unit is one of the larger
units and contains a lot of vocabulary to keep straight. In order the help the
students I have created this study option for home.
Key terms will be added as we introduce them in class- I will put the new
terms in a new chart to cut down on printing waste, but the same document
will be sent home each time.
A copy of this document will also be posted on my teacher website located
at: http://www.greenwoodsd.org/Page/1009
To use as Flash Cards:
1. Cut only on solid lines.
2. Fold the card on the dotted line and put a small piece of tape on
the open end to secure and make the flash card that should show
the definition on one side and the vocabulary word on the other.
To Use a Matching Activity:
1. Cut the chart apart completely by cutting on all lines.
2. Have your child mix up the cards and try to match the correct
definition with the correct vocabulary term.
(A second chart can be printed to act as a key)
Fluid Mosaic
Describes the cell membrane. Fluid due to
movement of phospholipids and mosaic due to
different molecules such as proteins embedded in
the phospholipids
Selective Permeability
Allows some but not all particles/molecules to
pass through
Phospholipids
Make up the cell membrane. Fluid. Hydrophilic
head and hydrophobic tails
Protein Pore
An open protein that allows certain particles to
pass through the cell membrane based on size and
shape
Protein Pump
A pump in the cell membrane which helps move
particles during active transport from areas of low
concentration to areas of high concentration
Protein Channel
A protein that binds to a signal molecule and
triggers a cellular response; based on size and
shape
Protein Receptor
A protein that detects a signal and acts because of
it. Ex: Insulin
Diffusion
The movement of molecules from areas of higher
concentration to lower concentration
(no energy required)
Facilitated diffusion
The movement of molecules from areas of high
concentration to low concentration using
transport proteins
Osmosis
The diffusion of water from hypotonic areas to
hypertonic areas
Hypertonic
Higher concentrations of particles
hypotonic
Lower concentrations of particles
Isotonic
A cell has the same concentration of particles
inside and out or moves at an equal rate
Passive Transport
The movement of molecules down the
concentration gradient from high to low without
using energy
Active Transport
The movement of molecules up their
concentration gradient from low to high using
energy
Concentration Gradient
The difference in the concentration of a substance
from one location to another
Endocytosis
The use of a vesicle to move larger particles across
the cell membrane so they may ENter the cell
Exocytosis
The use of a vesicle to move larger particles across
the cell membrane so that they may EXit the cell
