Answer
  • 1. Organelles 2. phospholipid bilayer
  • 1. Golgi Bodies 2. Cystol
  • 1. Organelles 2. Cystol
  • 1. Organelles 2. Extracellular Fluid

Question 2

Question
The Fluid Mosaic Model describes the cell membrane as being what?
Answer
  • 1. The mosaic nature of scattered proteins within a flexible matrix of phospholipid molecules.
  • 2. The rigid nature of the phospholipid bilayer with a few membrane proteins to help with recognition and transportation of molecules
  • 3. The mosaic nature of scattered proteins within a solid matrix made of cellulose

Question 3

Question
Three types of of proteins on the cell membrane are peripheral proteins, Chained proteins, and transmembrane proteins
Answer
  • True
  • False

Question 4

Question
Which type of transmembrane protein provides open passageways through the membrane for certain hydrophilic substances such as polar and charged molecules?
Answer
  • Aquaporins
  • Channel proteins
  • Ion channels
  • Porins

Question 5

Question
Ion Channels....
Answer
  • Use energy to transport materials across the membrane through a process called active transport. The Na+ - K+ pump
  • Allows the passage of ions across the membrane. In nerve and muscle cells. This also includes gated channels which open and close in response to specific chemical or electrical stimuli to allow the passage of specific ions such as Na+ and K+
  • allow passage of certain ions and small polar molecules
  • Allow only large charged molecules to transfer

Question 6

Question
Porins are found in the plasma membrane of certain cells and dramatically increase the passage rate of H2O molecules
Answer
  • True
  • False

Question 7

Question
Carrier proteins bind to specific molecules, which changes shape and passes across into the cell E.g. glucose
Answer
  • True
  • False

Question 8

Question
The difference between adhesion proteins and receptor proteins is that adhesion proteins attach to neighboring cells and provide internal filaments and tubules for stability, while receptor proteins are used as a binding site for hormones and other trigger molecules
Answer
  • True
  • False

Question 9

Question
The function of Glycoproteins are what?
Answer
  • Used to help the ER assemble ribosomes by attaching polysaccharide groups to polypeptides
  • To add rigidity to the cell membrane of animal cells under normal temperature
  • A carbohydrate coat that covers the outer surface of the cell wall of some bacteria and the cell membrane of some animals. Provides adhesive capabilities, and a barrier to infections.
  • used to distinguish between self and foreign cells and bacteria

Question 10

Question
What adds rigidity to the membrane of plant cells under normal conditions?
Answer
  • Cholesterol
  • Glycocalyx
  • sterols
  • Porins

Question 11

Question
The rough ER is responsible for creating glycoproteins, while the smooth ER is used for creating lipids and hormones.
Answer
  • True
  • False

Question 12

Question
What is the gel like substance between organelles that makes up the streaming movement within the cell
Answer
  • Cystol
  • Extracellular fluid
  • Cytoplasm
  • Water

Question 13

Question
What two subunits make up Ribosomes in prokaryotes and what are they made of?
Answer
  • rRNA and Protein 60S +30S
  • RNA and Protein 60S+40s
  • rRNA and Protein 50S + 30S
  • rRNA and Protein 60S + 40S

Question 14

Question
The Golgi apparatus is responsible for transport of various substances in vesicles
Answer
  • True
  • False

Question 15

Question
Peroxisomes: break down waste such as nutrients/bacteria/cell debris
Answer
  • True
  • False

Question 16

Question
What are microtubules made of?
Answer
  • actin
  • tubulin
  • microfilaments
  • structural proteins

Question 17

Question
What organizes microtubules in flagella and cillia
Answer
  • MTOCs
  • MTOAs
  • MTCs
  • Centrisomes

Question 18

Question
Which of these provides support for maintaining cell shape
Answer
  • Microtubule
  • Microfilaments
  • Intermediate filaments
  • MTOCs

Question 19

Question
Contractile vacuoles are only found in prokaryotes
Answer
  • True
  • False

Question 20

Question
Storage vacuoles are used to occupy most of the plant interior, exert turgor when fully filled to maintain rigidity. They also carry of the functions of lysosomes
Answer
  • True
  • False

Question 21

Question
Cell Walls are only found in plants and bacteria, and are made up of cellulose, chitin, peptidoglycans, and polysaccharides.
Answer
  • True
  • False

Question 22

Question
Which of the following is an Anchoring Junction?
Answer
  • desmosomes
  • Gap junctions
  • Plasmodesmata
  • Tight junctions

Question 23

Question
Tight junctions do what?
Answer
  • Produces a seal that prevents the passage of materials between cells. characteristic of cells lining the digestive tract.
  • Contain narrow tunnels that allows the passage of ions and small molecules;
  • Are used to send chemical and electrical signals between cells
  • Provide mechanical stability and holds structures together
