25 Cards in this Set
| Front | Back |
|---|---|
|
Double membrane-bound organelle that contains genetic information encoded on chromosomes
|
Nucleus, Chloroplast(genomes from photosynthesis), Mitochondria(genomes from ATP/Protein)
|
|
Provides structural support and protection for plant cells
|
Cell Wall
|
|
A complex of RNA and protein that is the site of proteins synthesis(translation)
|
Membrane Associated Ribosome
Free Ribosome
|
|
Network of membranes containing enzymes responsible for synthesizing lipids and breaking down toxins.
|
Smooth Endoplasmic Reticulum
|
|
A common second messenger in cell-cell signaling
|
Cyclic AMP (cAMP) messenger after the hormone which is insoluble and unable to get through the membrane.
|
|
Organelle that contains membranes called cristae, it is responsible for producing
|
most of the cell's ATP
Mitochondria
|
|
9+2 structure of microtubules in cilia and flagella
|
Axoneme (made of microtubules and moves through dynein)
|
|
Proteins are targeted to specific locations in the endomembrane system using these as addresses
|
Vesicles, Signal Sequencing, Carbohydrate tag to fit specific receptor
|
|
Digests food items or autodigests damaged organelles through acid hydrolysis.
|
Lysosomes
|
|
Stacks of flattened membranes called cisternae, in which proteins are modified (for example, glycosylated) after they are synthesized.
|
Golgi Apparatus (glycosylated: adding carbohydrate groups)
|
|
This occurs during transduction in cell-cell signaling and amplifies the strength of the metabolic response to the cell's reception of a hormone.
|
Phosphorylation Cascade (Kinase sends a phosphate to molecule)
|
|
Site of reactions that fix inorganic carbon (CO2) onto organic compounds using the
energy from light.
|
Chloroplast
|
|
Structural support for the cell, it is made up of microtubules, microfilaments and
intermediate filaments.
|
Cytoskeleton
|
|
Localized region in the nucleus where ribosomal genes are expressed and
ribosomes are partially assembled.
|
nucleolus
|
|
Binds to a cytosolic receptor, and usually results in a major change in the long-term
development or function the cell
|
Lipid Soluble Hormone, Steroids
|
|
A protein that uses ATP to move ions against their concentration gradients
|
Active Transport/Sodium-Potassium Pump
|
|
Microtubules
|
Major Protein: Tubulin
Motor Proteins: Dynein and Kinesin(vesicle transportation)
Functions: Maintain cell shape (resist compression), movement via cilia and flagella
|
|
Microfilaments
|
Major Protein: Actin
Motor Proteins: Myosin
Functions: Move organelles, maintain cell shape (resist tension)
|
|
Intermediate Filaments
|
Major Protein: Keratins, Nuclear Lamins
Motor Protein: N/A
Functions: Anchor nucleus, Maintain cell shape (resists tension)
|
|
Virchow
|
All cells come from pre-existing cells
|
|
Schleiden
|
Plants are made up of 1 or more cells
|
|
Schwann
|
Animals are made up of 1 or more cells
|
|
Transduction
|
1. Amplification through phosphorylation cascade
2. Regulate
|
|
Functional Groups
|
Phosphate
Carboxyl Group (carboxylic acid)
