What organelle is the site of protein synthesis?
Ribosome
100
What organelle is the site of cellular respiration?
Mitochondria
100

These are the 5 types of cell contacts, which include cell to cell and cell to ECM

Tight junctions, gap junctions, Desmosomes

Hemidesmosomes, focal adhesions

100
What happens to a cell in a hypertonic solution?
Shrinks
100
Why are cells small?
Larger surface area for nutrient exchange.
200
What organelle's structure resembles a hollow stack of pancakes?
Golgi apparatus
200
What is the structure that separates the inside of the cell from the outside?
Plasma/cell membrane
200

Some  components in ecm 

Collagen, elastin, proteoglycans,

Fibronectin, amino 

200
What is an isotonic environment like?
equal movement of water into and out of the cell.
200

The central dogma 

DNA -> RNA-> protein 

300

What is the structure of a nucleus like?

Double membrane with pores.

300

What is the role of a vacuole

Storage site

300
What organelle is the "powerhouse"?
Mitochondria
300
Where does the water move in a hypotonic solution?
water moves into the cell
300

The components in a subunit of DNA/RNA

Phosphate group, nitrogenous base, ribose or deoxygenated ribose

400
What adds support to the cell and aids in organelle movement?
cytoskeleton
400
What is the function of the nucleus?
Information center/control center of the cell.
400
Primary components in the cell membrane 

phospholipids 

400

Phases in the cell cycle 

prophase, metaphase, anaphase, telophase 

400

In the lab, when I want to put in a green fluorescent Scamp1 or other protein of interest, I use a plasmid that has the DNA for the protein of interest in it. Why do I not just inject the protein of interest? 

DNA is more stable 

Protein expression will end, but with plasmid DNA it will last longer. 

500

What organelle contains digestive enzymes? 

lysosome

500
What is the role of the golgi apparatus?
modifies, packages, and send proteins throughout the cell
500

3 general types of cytoskeletal elements

Microfibrils, intermediate filaments, microtubules 

500

Progenitor cell that can produce several cell types 

Pluripotent cells

500
What is the chemical equation of cellular respiration?
carbs + oxygen ---> CO2 + H2O + energy
