Functions of Membrane Proteins
How many funtions are there for membrane proteins
What are the six functions of membrane proteins
A= Attachment to the cytoskel and extracellular matrix
S= Signal transduction
C= Cell to cell recognition
I= Intercellular joining
What are the 2 types of proteins?
Phospholipids and Proteins
Every Cell has WHAT?
What are the four types of macromolecules? Ntk just 3
What is anothe name for the fluid mosaic model?
What is plasma membrane made up of?
Phospholipid is what kind of molcule?
What kind of movement do plasmamembranes have?
What reduces membrane fluidity and acts as a "temporary buffer"?
What are the pores on a plant cell called?
PLASMODESMATA AND MADE UP OF CELLULOSE
What is the outer layer of a plant cell ?
The nucleus of a cell keeps what out?
DNA AND RNA
What is transportated through the nucleus pores
What maintains the nucleus shape?
The nuclear LAMINA
What is synthesized at the NUCLEOLUS?
DNA turned into RNA is called what
Where does transcription occur?
Inside the nucleus
What basically are chromosomes?
DNA and RNA
What 2 things do ribosomes have?
Proteins and rRNA complexes
What do ribosomes do?
When RNA is turned into proteins, this is called?
The nucleus has two membranes called?
What are the types of E.R are there?
Two , Smooth and Rough
What does Rough E.R have and what does it do?
Rough E.R has ribosomes and does protein synthesis
Rough E.R structure are big or small
Really, really small
What does the letters E.R mean?
What does smooth E.R do?
Synthesizes secretary proteins which are internalized, glycosylated, and transportated to GOLGI
Smooth E.R has 3 functions:
: lipids and cholesterol
Our liver has TONS of these cells
Is Golgi attached to the nuclear membrane
So what is attached to the Nuclear Membrane?
Lysomes are only in animal or plant cells?
Lysosomes digestive enzymes break down:
When lysosomes digest food, this is called:
When lysosomes break down damaged organelles, this is called:
How do mitochondria produce energy?
Through cellular respiration
What is ATP?
Adenosine Tri Phosphate
Mitochondreal DNA is in the:
Cellular respiration is also called:
How many mitochondria do cells have?
Hundreds or even thousands
In Mitrochondria, the outer layer is smooth or convoluded?
In mitochondria, the inner layer is:
Folded and Convoluded
The folded membrane of mitochondria is:
Cristae and is folded
Chloroplasts are in animal or plant cells?
Plants cells have pancake stacks called:
Microtubles have microfilaments also known as:
Centrosomes are only in Animal or Plant cells and have?
Animal cells and have CENTROSOMES
Centrosomes are needed to:
What do Microtubles separate?
Chromas during cell division
Actin Filaments provide:
All microtubles have cell motility called:
When cells divide, the space where they divide is called
