1The Cytoplasm consist of specialized bodies called 1. _________ suspended in a fluid matrix, the 2. __________ which consist of water and dissolved substances such as proteins and nutrients
- A1. Organelles
2. phospholipid bilayer - B1. Golgi Bodies
2. Cystol - C1. Organelles
2. Cystol - D1. Organelles
2. Extracellular Fluid
- A1. Organelles
2The Fluid Mosaic Model describes the cell membrane as being what?
- A1. The mosaic nature of scattered proteins within a flexible matrix of phospholipid molecules.
- B2. The rigid nature of the phospholipid bilayer with a few membrane proteins to help with recognition and transportation of molecules
- C3. The mosaic nature of scattered proteins within a solid matrix made of cellulose
3Three types of of proteins on the cell membrane are peripheral proteins, Chained proteins, and transmembrane proteins
- ATrue
- BFalse
4Which type of transmembrane protein provides open passageways through the membrane for certain hydrophilic substances such as polar and charged molecules?
- AAquaporins
- BChannel proteins
- CIon channels
- DPorins
5Ion Channels....
- AUse energy to transport materials across the membrane through a process called active transport. The Na+ - K+ pump
- BAllows 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+
- Callow passage of certain ions and small polar molecules
- DAllow only large charged molecules to transfer
6Porins are found in the plasma membrane of certain cells and dramatically increase the passage rate of H2O molecules
- ATrue
- BFalse
7Carrier proteins bind to specific molecules, which changes shape and passes across into the cell E.g. glucose
- ATrue
- BFalse
8The 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
- ATrue
- BFalse
9The function of Glycoproteins are what?
- AUsed to help the ER assemble ribosomes by attaching polysaccharide groups to polypeptides
- BTo add rigidity to the cell membrane of animal cells under normal temperature
- CA 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.
- Dused to distinguish between self and foreign cells and bacteria
10What adds rigidity to the membrane of plant cells under normal conditions?
- ACholesterol
- BGlycocalyx
- Csterols
- DPorins
11The rough ER is responsible for creating glycoproteins, while the smooth ER is used for creating lipids and hormones.
- ATrue
- BFalse
12What is the gel like substance between organelles that makes up the streaming movement within the cell
- ACystol
- BExtracellular fluid
- CCytoplasm
- DWater
13What two subunits make up Ribosomes in prokaryotes and what are they made of?
- ArRNA and Protein
60S +30S - BRNA and Protein
60S+40s - CrRNA and Protein
50S + 30S - DrRNA and Protein
60S + 40S
- ArRNA and Protein
14The Golgi apparatus is responsible for transport of various substances in vesicles
- ATrue
- BFalse
15Peroxisomes: break down waste such as nutrients/bacteria/cell debris
- ATrue
- BFalse
16What are microtubules made of?
- Aactin
- Btubulin
- Cmicrofilaments
- Dstructural proteins
17What organizes microtubules in flagella and cillia
- AMTOCs
- BMTOAs
- CMTCs
- DCentrisomes
18Which of these provides support for maintaining cell shape
- AMicrotubule
- BMicrofilaments
- CIntermediate filaments
- DMTOCs
19Contractile vacuoles are only found in prokaryotes
- ATrue
- BFalse
20Storage 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
- ATrue
- BFalse
21Cell Walls are only found in plants and bacteria, and are made up of cellulose, chitin, peptidoglycans, and polysaccharides.
- ATrue
- BFalse
22Which of the following is an Anchoring Junction?
- Adesmosomes
- BGap junctions
- CPlasmodesmata
- DTight junctions
23Tight junctions do what?
- AProduces a seal that prevents the passage of materials between cells. characteristic of cells lining the digestive tract.
- BContain narrow tunnels that allows the passage of ions and small molecules;
- CAre used to send chemical and electrical signals between cells
- DProvide mechanical stability and holds structures together
24Check all of the following that Prokaryotes don't have
- ANucleus
- Bnaked DNA
- Cribosomes
- DCell walls
- EPlasma membrane
25Receptor mediated endocytosis is a type of pinocytosis that uses ligands to bind to specific dissolved molecules and fold the into the plasma membrane in vesicles
- ATrue
- BFalse
