25
The endoplasmic reticulum is a maze of folded membranes where_______and_______ are produced
Protein;lipids
26
The mitochondria converts food into_______that is useable by a cell
Energy
27
Strengthens the cell membrane
Cholesterol
28
Help make materials cross the membrane and are also part of the cytoskeleton
Proteins
29
Helps identify cell types
Carbohydrates
30
True/false a membrane is fluid, because the phospholipids in each layer can move from side to side, in and out of the cell, by sliding past each other, and by spinning in circles.
False
31
True/false a selective permeable membrane allows all molecules to cross
False
32
A receptor/ phospholipid detects a signal molecule and carries out an action in response.
Receptor
33
A ligand is a molecule that acts as a receptor/signal when it binds to a receptor/ signal
Signal; receptor
34
A ligand can cross/ cannot cross the cell membrane can bind to an intracellular receptor
Can cross
35
A ligand that can cross/ cannot cross the cell membrane can send a message to a cell by binding to/ taking off a membrane receptor,which then changes shape
Cannot cross; binding to
36
The fluid mosaic model describes the arrangement of the________ that make up a cell membrane. The model includes both the fluidity of the membrane and the variety of molecules that make up the membrane.
Molecules
37
Selective_________ means that the cell membrane allows some, but not all, molecules to cross
Permeability
38
The difference in the concentration of a substance from one location to another is called a
Concentration gradient
39
A molecule that diffuses down a concentration gradient goes from an area of______ concentration to an area of______ concentration.
Higher;lower
40
A cell may transport a substance in lysosomes/ vesicles if the substance is too large to cross the membrane.
Vesicles
41
During endocytosis, the vesicle membrane fuses with a lysosome, and the membrane and it's contents are broken down by lysosomal enzymes/ gradients.
Lysosomal enzymes
42
Uses energy
Endocytosis and exocytosis
43
Takes substances into a cell
Endocytosis
44
Releases substances outside a cell
Exocytosis
45
Moves substances in vesicles
Endocytosis and exocytosis
46
Active transport/ phagocytosis is a term that means "cell eating". It describe a type of endocytosis.
Phagocytosis
47
Active transport/ facilitated diffusion drives molecules across a membrane against a concentration gradient.
Active transport
48
Which invention played the biggest role in the discovery of cells by early scientist?
Compound microscope
49
The cell theory states that all organisms are made of cells; cells are the most basic unit of life; and
All existing cells are produced by other living cells

66
The movement of molecule down a concentration gradient through transport proteins in the cell membrane is a type of
Facilitated diffusion
67
The difference in the concentration of dissolved particles from one location to another is called a
Concentration gradient
