Cell Basics
These cells can divide/renew over long periods.
What is stem cells.
Nucleus, mitochondria, lysosome, Golgi apparatus, rough ER, smooth ER.
What is organelles you can find in mammalian cells?
The powerhouse of cell, supplies cell with ATP
What is the mitochondria?
A cell secreting signal molecules that can bind back to its own receptors
What is autocrine signaling?
These cells have no organelles
What are RBCs?
The cells with a well-defined nucleus containing DNA
What is eukaryotic cells?
Phospholipids such as Phosphatidylcholines, phosphatidylserine, sphingomyelin and cholesterol
What are the lipids make-up the plasma membrane?
Organelle involved in modifying and packaging proteins
What is the golgi apparatus?
Transmembrane proteins which are matrix receptors for collagen, vitronectin, fibronectin...
What is integrins?
The type of cells which have a ton of lysosomes
What is white blood cells?
This is the amount of water in cells.
What is 70%?
The site of protein synthesis in eukaryotic cells.
what are ribosomes?
Organelle decorated with ribosomes.
What is Rough ER?
Adherens, Desmosome, Hemidesmosomes, Gap junctions and Tight junctions
What are cellular junctions?
These cells make up a good portion of tendons and ligaments.
What are fibroblasts?
A neuron that sends impulses from your big toe to the base of your spine
What is a longest cell in the body?
The fluid like substance within the cell.
What is cytosol?
A network of fibers that provides structure and mechanical support for the cells
What is the extracellular matrix?
Thyroid and adrenaline hormones secreted to act at a distant location.
What is endocrine signalling?
The number of binding sites on the ribosomes for mRNA
What is ONE?
A process where foreign agents/dead cells/material is engulfed by cells.
What is phagocytosis?
The nucleolus plays an important role in the assembly of this non-membranous organelle.
What is ribosome?
A porous channel that connect the nucleus and cytoplasm.
What is nuclear pore complex?
Signaling proteins that help control inflammation, allow immune system to mount a defense.
What are cytokines?
Cytoskeletal elements involved in chromosal and organelle movement.
What is microtubules?
