Cellular respiration in animal cells & photosynthesis in plant cells (2 answers)
mitochondria and chloroplast
What is the fluid mosaic model? draw on board if needed
proteins are embedded in the phospholipid bilayer
in what way do the membranes of eukaryotic cells vary?
a. phospholipids are found only in certain membranes
b. certain proteins are unique to each membrane
c. only certain membranes of the cell are selectively permeable
b. certain proteins are unique to each membrane
What is the endosymbiont theory?
the theory that mitochondria and plastids, including chloroplasts, originated as prokaryotic cells engulfed by an ancestral eukaryotic cell. The engulfed cell and the host cell then evolved into a single organism
ribosomes
What is not part of the endomembrane system?
a. nuclear envelope
b. chloroplast
c. golgi
d. plasma membrane
b. chloroplast
What is the difference between integral and peripheral proteins?
Integral: embedded in the bilayer
Peripheral: attached to the surface
According to the fluid mosaic model, proteins of the membrane are mostly:
a. spread in a continuous layer over the inner and outer surfaces
b. confines to the hydrophobic interior
c. embedded in the lipid bilayer
c. embedded in the lipid bilayer
What is the fundamental unit of life
cells
Two types. One synthesizes lipids, metabolizes carbs, and detoxes drugs/poisons. The other aids in synthesis of proteins (bound ribosomes) and adds carbs to proteins to make glycoproteins
Smooth ER and Rough ER
which structure is common to plant AND animal cells?
a. chloroplast
b. wall made of cellulose
c. centriole
d. mitochondria
d. mitochondria
What is it called when water diffuses out through the permeable membrane?
osmosis
which of the following would tend to increase membrane fluidity?
a. greater proportion of unsaturated phospholipids
b. a lower temp
c. a greater proportion of saturated phospholipids
a. a greater portion of unsaturated phospholipids
animal and plant cells are both?
eukaryotic
Modifies proteins, carbs on proteins, and phospholipids.
golgi
which is present in a prokaryotic cell?
a. mitochondra
b. ribosomes
c. ER
b. ribosomes
If the solution outside has a high concentration of what is that called?
hypertonic
Which process includes all others?
a. osmosis
b. diffusion of a solute across a membrane
c. facilitated diffusion
d. passive transport
food vacuoles are formed by
phagocytosis
breakdown of ingested substance, cell macromolecules, and damaged organelles for recycling
lysosome
Come up and draw the correct structure of flagella and cilia. What are they?
motile appendages containing microtubules
What is isotonic?
When the concentrations on outside and inside are equal
What is osmoregulation
what are 3 things plant cells have that animal cells don't
cell wall
central vacuole
