What is not a function of the plasma membrane?
Outer boundary of the cell
Permeable to everything
Separates intracellular fluids from extracellular fluid
Cell communication and signaling
What are the 2 primary components of the plasma membrane (select both that apply)?
Lipids
Proteins
Carbohydrates
Nucleic Acids
Which description explains why the Fluid Mosaic Model is "fluid".
The proteins are floating within the structure, which creates a constantly changing mosaic pattern among the lipids.
The lipids are floating in the liquid due to the hydrophilic and hydrophobic heads which lock the protein structure in place as one solid layer.
The Fluid Mosaic Model is mostly water, which makes it fluid.
There is constant, or fluid-like, movement of molecules through the plasma membrane as it allows everything to pass through it
Which of the following is not a type of lipid found in the plasma membrane?
Phospholipid
Glycolipid
Cholesterol
Integral Protein
How many different ways are there to get into a cell?
1
2
3
4
Infinite
Oxygen tends to move from highly oxygenated blood into the blood cell with very little, or no oxygen. As a result, oxygen requires no energy to move into a blood cell. This is an example of which of the following?
Passive Membrane Transport
Active Membrane Transport
Selective Diffusion
ATP Production
In endocytosis, a white blood cell chases a bacterium to engulf it within the plasma membrane from the environment and into the white blood cell for destruction. What is this an example of?
Passive Membrane Transport
Active Membrane Transport
Selective Diffusion
ATP Production
What are the 3 most important ions used in selective diffusion in the human body? Select all that apply.
Water (H20)
Sodium (Na)
Potassium (K)
Chlorine (Cl)
Which type of cell transport does not require energy to move a molecule across the plasma membrane?
Passive Membrane Transport
Active Membrane Transport
Selective Diffusion
ATP Production
How long did it take for the first cell to evolve?
Thousands of years
Hundreds of thousands of years
Millions of years
Billions of years
Which organelle is responsible for ATP Production for the cell?
Nucleus
Mitochondrion
Ribsome
Endoplasmic Reticulum
Which organelle is responsible for protein synthesis?
Ribosome
Nucelus
Mitochondrion
Lysosome
What is the difference between Rough Endoplasmic Reticulum (RER) and Smooth Endoplasmic Reticulum (SER)?
SER has ribosomes attached to the surface.
RER has ribosomes attached to the surface.
RER has free ribosome floating in cytosol.
RER is attached to the SER.
Which organelle provides the site for dangerous and powerful enzymes to take place?
Nucelus
Ribosome
Lysosome
Mitochondrion
Which organelle provides strength and stability for the cell?
Cytoskeleton
Rough Endoplasmic Reticulum
Smooth Endoplasmic Reticulum
Golgi Apparatus
What are the 2 major periods of the Mitotic Cell Cycle?
Interphase
Mitotic Phase AKA Mitosis AKA M Phase
Anaphase
Prophase
In the Mitotic Cell Cycle, when does DNA replicate?
G1 Phase
S Phase
G2 Phase
Mitosis
What is the last phase of Mitosis?
Prophase
Metaphase
Anaphase
Telophase
What is not a function of the mitotic cell cycle in the body?
Repair
Growth
Development
Movement
True or False: through the mitotic cell cycle, two daughter cells are produced that are genetically identical to the original cell.
True
False
True or False: a cell that is not currently reproducing (or has stopped dividing) is in G1 phase.
True
False
