Week 2 Flashcards
The plasma membrane is made of
A phospholipid bilayer
Channel protein
Provide an opening for movement in and out of the cell
Gated channel protein
Close or open depending on the condition
Carrier protein
Pick up specific molecule that fits in the fold and flips it to fit in the cell
Active transport protein
Requires energy (ATP), always moves in the same direction
Where is genetic info found
The nucleotide
Cell wall
Rigid, gives shape and protects it from bursting
Flagellum
Rotate to provide mobility
Thylakoid
Provides a membrane for photosynthesis
Capsule/sheath
Is a sticky layer that protects cell from attack or dehydration
Plasmid
Accessory genetic information, they can pass genetic info back and forth between plasmid
Ribosome
Sure of mRNA translation and protein synthesis
Cytosol
Complex mixture of enzymes and any other molecules in water
Cilium
Coordinates beating to provide motility
Smooth endoplasmic reticulum
Synthesis of lipids, steroid hormones, the detoxification of harmful metabolic byproducts and the storage and metabolism of calcium ions within the cell
Rough endoplasmic reticulum
Synthesis of proteins to be packaged
Vesicle
Small membrane sack of material
Golgi apparatus
Packaging modifying and sorting proteins from the endoplasmic reticulum
Vacuole
Larger membrane sacks of material
Lysosome
Vacuole of digestive enzyme
Chromatin
Genetic info, several diffuse chromosomes, each chromosome is one double stranded DNA molecule with associated proteins
Nucleolus
Site of assembly ribosomes
Nuclear envelope
Barrier surrounding the chromatin
Mitochondrion
The production of ATP for the cell
Inner membrane
Inside the membrane there is a fluid called the matrix floating around the matrix are ribosomes
Cytoskeleton
Cell shape, cell movement and intracellar transport
Extracellular matrix
Strengthens tissues help cell to react to environment
Cholesterol
Helps maintain membrane fluidity
Enzyme
A protein that facilitates a specific chemical reaction
Identification makers
Allow the cells to be recognized
Tight junction proteins
Holds the cells together
Cytosis
Transport mechanism for the movement of large quantities of molecules into and out of cells
ATP
A high energy molecule used to provide energy in cells
ADP
Lower energy form of ATP
NADH, FADH2, NADPH
High energy molecules carrying high energy electrons
NAD+, FAD+, NADP+
Lower energy forms of molecules without high energy electrons
Cellular respiration
C6H12O6 + O2 -> CO2 + H20 + ATP
