Regulation of Cell Contents
The purpose of the cell membrane is to
Regulate what enters and leaves the cell
Glucose passing into the cell through a protein channel is an example of
Facilitated Diffusion
What is the main function of Ribosomes?
Construct proteins
The Powerhouse of the cell is often the analogy made for the
Mitochondria
What are the two major types of cells?
Eukaryotes and prokaryotes
The cell membrane is mostly made out of
Phospholipids
Solutes always diffuse from
High concentration towards low concentration
Vesicles are membranes that mainly do what?
Transport material around the cell
These have multiple membranes and make energy using active and passive transport
Mitochondria
What five organelles do ALL cells have in common?
Cell membrane
Cytoskeleton
Cytoplasm
DNA
Ribosomes
Where are transport and channel proteins most likely to be found?
Cell membrane
During osmosis water flows towards what
Towards a hypertonic solution
This is responsible for first making proteins and transporting them out into the cytoplasm
Rough endoplasmic reticulum
This organelle is made of microtubules, intermediate filaments, and microfilaments
Cytoskeleton
This is responsible for detoxification of the cell and making vesicles
Smooth endoplasmic reticulum
This is formed because the heads of phospholipids are hydrophilic and the tails are hydrophobic
Phospholipid bilayer
During diffusion substances flow towards
equilibrium or creating isotonic solutions
These are membranes with digestive enzymes in them and are responsible for breaking down wastes and cleaning up the cell.
Lysosomes
This has multiple membranes, pores, ribosomes, DNA, and also a special spot that makes ribosomes.
The Nucleus
This surrounds the nucleus and is covered in pores and ribosomes
The nuclear envelope
What does the fluid-mosaic model describe?
The Cell membrane and all of it's proteins
Placing an animal cell in a hypertonic solution would cause it to
shrink
This takes in vesicles from the ER and puts the finishing touches on proteins before sending them to various parts of the cell.
Golgi Apparatus
These are very small filaments that make up the contracting proteins of a muscle called actin.
microfilaments
What organelle is a major player during cell division in animal cells?
Centrioles
