16
Q

where does cellular respiration occur

A

michtochondria

17
Q

if a molecule is larger what does that mean for the SA/volume ratio

A

the larger something is the lower the SA/V ratio meaning its harder for molecules to enter or leave

18
Q

what is a hypotonic solution

A

a solution that when a cell is placed inside of it it will burst because its low solute

19
Q

what is an isotonic solution

A

same amount t of solute inside and outside the cell

20
Q

what do lysosomes do

A

digest material

21
Q

what is an example of active transport

A

sodium potassium pump

22
Q

how do substances move in active transport

A

against there gradient, low to high

23
Q

how does water move in osmosis

A

high water concentration to low water conentration

24
Q

where is ATP produced

A

michtochondria

25
Q

what’s the difference between active transport and passive trasnport

A

active transport requires atp because It goes against the gradient

26
Q

what in the cells uses ATP to pump water and molecules

A

contractile vacuole

27
Q

what is phagocytosis

A

when a cell engulfs molecules and puts them into a vacuole and get digested

28
Q

what is endocytosis

A

when ur cell brings in molecules and USES them

29
Q

what is pinocytosis

A

when a cell takes in dissolved particles and drinks them and puts them into a vesicle

30
Q

is pinocytosis a form of active or passive transport

A

active because it requires atp

31
Q

is phagocytosis passive or active transport

A

active because it requires atp

32
Q

are endocytosis and exocytosis active transport or passive

A

active be cause they require energy

33
Q

wheres ATP produced

A

michtochondria

34
Q

what dissolves molecules taken in

A

lysosomes

35
Q

what is the function of RNA polymerase

A

connects to the untranscribed DNA in the nuclease and converts it to mRNA that is able to leave the nucleus

36
Q

cells that are larger have a ——- SA to V ratio

A

smaller

37
Q

what are the two main parts of the MODERN CELL THEORY

A

cells are the basic units of structure and function in living things. and all cells come from pre existing cells

38
Q

how is ATP REALEASED

A

when a phosphate group is removed from ATP and it becomes ADP
