What is the main structure of the cell membrane called?
The phospholipid bilayer
100
Movement of molecules without energy is called what?
Passive Transport
100
What is the main function of the cell membrane?
To regulate what enters and leaves the cell, maintaining homeostasis
100
This macromolecule is the body’s main source of quick energy.
Carbohydrates
100
I modify, sort, and package proteins before they are transported elsewhere. Who am I?
Golgi Bodies
200
Which is the hydrophilic part and hydrophobic part?
Hydrophilic = heads, Hydrophobic = tails
200
Which type of transport is this?
Passive transport (facilitated diffusion)
200
What characteristic of life does the image represent in the cell?
The balance of internal conditions (homeostasis)
200
Proteins are made of smaller building blocks called these.
Amino Acids
200
What is the organelle that is purple?
Rough ER
300
Which type of molecule helps stabilize the membrane’s flexibility?
Cholesterol
300
Movement of water across a membrane is called what?
Osmosis
300
Give an example of how cells maintain balance in solute concentrations.
Using active transport or osmosis to adjust levels inside and outside the cell
300
Fats, oils, and waxes all belong to this macromolecule group.
Lipids
300
I contain enzymes that break down wastes and damaged cell parts. Who am I?
Lysosomes
400
WHat type of protein is below?
What is a transport (integral) protein?
400
During diffusion, particles move from an area of ________ concentration to an area of ______ concentration
High, Low
400
The cell membrane is often compared to what in real life?
A security gate, selective barrier, a door
400
DNA and RNA are examples of this type of macromolecule.
Nucleic Acids
400
This organelle captures light energy and allows plant cells to perform photosynthesis.
Chloroplast
500
Explain the “fluid mosaic model” of the cell membrane.
The membrane is flexible, with proteins and lipids floating and moving within it like a mosaic.
500
When the concentration of a substance is equal on both sides of a membrane, the system has reached this state.
Equilibrium
500
This term describes a membrane that allows some substances to pass through but blocks others.
Selectively permeable
500
This macromolecule contains carbon, hydrogen, oxygen, and nitrogen and is used to build structures and enzymes.
Proteins
500
Put these structures in the correct order for a protein that will be transported out of the cell: Golgi apparatus, ribosome, rough ER, vesicle.
Ribosome → rough ER → Golgi apparatus → vesicle
