GIRLS WITH MANLY NAMES
We will have a quiz about this and this is good for a reviewer for long quizzes and quarterly exams this quarter..soooo yeah. :DD
Cell membrane- Organic compounds (proteins, lipids and carbohydrates)
- regulates the movement of materials in and out of the cell
Dietary Lipids-3 fatty acids & 1 glycerol
Phospholipids- 2 fatty acids and 1 phospate group
(phosphorous + oxygen)
Fluid Mosaic Model
hydrophilic- attracted to water
hydrophobic- unattracted to water
The head is Hydrophilic while the Tail is Hydrophobic.
The thing that helps cell molecules respond to their environment that is a part of the function of the cell membrane is: "Proteins"
allows particular molecule to pass through freely as it enters/exits the cell.
A protein that selectively interacts with a specific molecule/ion so that it can cross the cell membrane to enter/exit the cell.
Cell Recignition Protein-
A glycoprotein that identify the cell.
A protein that is shaped in such a way that a specific molecule can bind to it.
It's kind of a lock and key relationship.
A protein that catalyzes a specific reaction.
Nucleus- (Robert Brown)
- control center of the cell (reproduction and protein synthesis)
Types of RNA
1.)mRNA (messenger)- will copy the genetic code so that it will leave the nucleus and put the copy to the ribosomes to make proteins.
2.)tRNA (transfer)- stays at the cytoplasm, waits for mRNA, interprets mRNA's copied code to be translated and further used in prontein synthesis.
3.)rRNA (ribosomal)- responsible for maintaining the ribosomes.
3 Main Parts of the Cell (animal and plant)
* cell membrane
structure where chromosomes are found in prokaryotes
Cytoplasm- (Johannes Purkinje)
suspends the various organelles; carried out various life functions.
Main Divisions and Regions of Protoplasm
Plant Cell Wall- made up of "cellulose fibrils" (pectin and lignin)
Bacterial Cell Wall- made up of peptidoglycan
Ribosomes- float freely in the cytoplasm
- site for protein synthesis
Mitochondria-site for cellular respiration; has an inner membrane called cristae which provide more surface area for greater cellular respiratory productivity.
Inner cavity into which the cristae project is called matrix.
Vacuoles- stores food, water and enzymes and excretes unnecessary wastes.
Lysosomes- used for digestion
- digests injured and dead cells
contains oxidative enzymes
Golgi Apparatus- (Camillo Golgi)
-system of flattened membrane-bound sacs that look like a stack of pancakes; involved in modifying and packaging.
Chloroplasts: (chloro= green, plasts= formed)
Carotenoid Pigments: (red,yellow,orange)
Anthocyanin: (red and violet)
also known as endomembrane system
-network of pathways through whichmaterials flow to different parts of the cytoplasm.
*Macrotubules- centrioles; chromosomes; 9+0
- flagella and cilia; 9 + 2
That is All!
Thank You :)
