one ion flowing out and one ion flowing into the cell

two ions flowing in the same direction

one ion flowing out and one ion flowing into the cell

two ions flowing in the same direction

What is an example of antiport?

chlorine channels in the respiratory cells

What is facilitated diffusion?

movement of ions down its concentration gradient without ATP

movement of ions down its concentration gradient using ATP

movement of ions up its concentration gradient using ATP

What is primary active transport?

movement of ions up its concentration gradient using ATP

movement of ions down its concentration gradient using ATP

movement of ions down its concentration gradient without ATP

movement of ions up its concentration gradient without ATP

What is secondary active transport?

movement of ions up its concentration gradient indirectly using ATP

movement of ions down its concentration gradient using ATP

movement of ions up its concentration gradient using ATP

movement of ions down its concentration gradient without ATP

What role do the microtubules have in the cytoplasm of the cell?

they hold the organelles in place for meiosis

they release the DNA or RNA fragments from the nucleus

they detoxify toxins to keep the cell alive

What is the nuclear envelope?

has pores that allows for the DNA and RNA materials to leave the nucleus

protects the nucleus from toxins

helps produce protein chains from translation of RNA

What is the role of the ROUGH Endoplasmic Reticulum?

produces the membrane proteins and phospholipids

detoxifies the cell and produces steroids

produces proteins for lysosomes

What is the role of the SMOOTH Endoplasmic Reticulum?

detoxifies the cell and produces steroids

produces the membrane proteins and phospholipids

produces proteins for lysosomes

What is the role of the ribosomes in the cell?

producing a protein chain from translation

found on the rough endoplasmic reticulum

packages up cellular material to be sent within the cell or out of the cell

break down the macromolecules of the cell

detoxify the cell from venom, alcohol, or drugs

What is the role of the lysosome of the cell?

break down the macromolecules of the cell

detoxify the cell from venom, alcohol, or drugs

packages up cellular material to be sent within the cell or out of the cell

What is the role of the mitochondria of the cell?

detoxify the cell from venom, alcohol, or drugs

packages up cellular material to be sent within the cell or out of the cell

break down the macromolecules of the cell

Semi-permeable mean to allow

only some materials across the membrane

all materials across the membrane

no material to cross the membrane

to allow only water across the membrane

What is the function of the smooth endoplasmic reticulum?

Lipid synthesis and detoxification
