These molecules make up the bilayer found in the cell membrane
phospholipids
This help to facilitate water movement across the membrane.
aquaporins
This organelle produces large amounts of ATP
mitochondria
In the process of transcription, mRNA is copied from this
DNA
A medical specialty dealing with tumors
oncology
This model describes when proteins are embedded in the phospholipids and can drift about in the phospholipids.
Fluid mosaic
The process by which water moves across membranes in response to solute concentration inside and outside of the cell.
osmosis
This organelle controls the cell’s activities and is responsible for inheritance.
nucleus
The process of making new proteins
protein synthesis
The cessation of cell division in response to contact with other cells
contact inhibition
Most lipids are made of this
phospholipids
This is a difference in the electrical charges between two separate areas.
electrical gradient
This organelle is involved in the cell’s protein synthesis.
ribosomes
A sequence of three DNA or RNA nucleotides that corresponds with a specific amino acid or stop signal during protein synthesis
codon
copies genetic instructions from DNA to mRNA, happens in nucleus
transcription
These proteins span the entire lipid bilayer
transmembrane
This transport uses energy in the form of ATP is expended to ‘pump’ a substance across a plasma membrane against its concentration gradient.
primary active transport
Enzymes found in this organelle can digest phagocytized bacteria, nonfunctional organelles, nucleic acids, proteins and lipids.
lysosomes
During DNA replication, this enzyme adds new nucleotides
DNA polymerase
cellular proteins that activate and deactivate CDKs, which initiate and regulation of DNA replication, mitosis, and cytokinesis
cyclins
This function of proteins distinguishes the cell from other body cells and foreign cells
identity markers
The non-specific uptake of fluids into the cell through the use of small vesicles.
Pinocytosis
The functions of this organelle include storing calcium ions, detoxification and hormone synthesis, and synthesis and packaging of lipids
Smooth ER
Somatic cell division happens during
mitosis and cytokinesis
The three things that happen when cells stop dividing
They snugly contact neighboring cells
Nutrients or growth factors are withdrawn
They experience contact inhibition
