unit 2 Flashcards
what does the Golgi apparatus do
packages & transports proteins, and makes rough er
what organelle allows for atp across the cell membrane
protein channels
what cell size is the most efficent
small
what dose high SA:V mean
a high SA:V makes the cell more efficient
what is the most common SA:V ratio
6:1
what is the role of proteins
transportation
what is an aquaporin
a water transport molecule, a protein
when is ATP used
when moving from low to high
can proteins be pores
yes
what are concentrated gradients
when something moves from high to low to reach net equilibrium
how dose water move
from high to low
what is phagocytosis used for
food(food vacuole)
what is pinocytosis used for
liquids(vesicle)
what dose phagocytosis and pinocytosis look like
the cell membrane raps around what it is taking in puts it in a food vacuole or a vesicle
what is endocytosis
the cell membrane raps around what it is taking in puts it in a food vacuole or a vesicle
what are two types of endocytosis
phagocytosis and pinocytosis
what part of a phospholipid is hyrophilic
the head
what part of a phospholipid is hydrophobic
the tail
if water wants to get through a membrane what dose it need to find
hydrophillic head
what is a channel protein used for
active transport (ATP)
what is a carrier protein used for
passive transport
what is osmosis
the diffusion of water
what is endosymbiont theory
when a cell takes in another cell and that cell does not stop working
what two parts of the ell were once no membraned
chloroplast and mitochondria
