Week 4: Cell Biology Flashcards
Which Organelle is unique to plants?
Chloroplasts
What is found between cells and outside of cells?
Interstitial Fluid
_________ __________ allow for selective transport of molecules, create an efficient separation and protection of cells, and have a bilayer of fatty acids and store cell products…
Cell membranes
T/F - Mitochondria is embedded in the plasmalemma
False, plasmalemma has channel proteins, glycolipids and carrier proteins
T/F Active transport uses ATP to move molecules through a membrane
True
The primary function of the mitochondrion as an organelle is to ….
Manufacture ATP
_____________ proteins are used for extracellular and intracellular signaling
Receptor proteins
The endoplasmic reticulum are….
a complex of lipid bilayer membranes
T/F Ribosomes only make protein in the nucleolus.
False, translate mRNA code to proteins, can be called ribozymes, composed of mRNA and protein
____________ means that a vacuole deposits products outside the cell by fusing with the plasmalemma
Exocytosis
The importance of membranes is highlighted by their ability to…
separate one environment from another
In a lipid bilayer membrane, the lipid molecules are lined up …
polar heads, facing out into the water environment
These selectively allow products to come into or out of the plasmalemma
Channel & carrier proteins
What is the primary function of the golgi complex?
modifies proteins and lipids into more useful molecules
T/F Mitochondrion have their own DNA loops so that they can instantly produce genetic information for manufacturing necessary proteins
True
