Q

what prefix is all enzymes in?

A

-ase

19
Q

what prefix is all sugars in?

A

-ose

20
Q

what is lactose?

A

a disaccharide and two sugars

21
Q

what is lactase?

A

ability to break lactose into smaller parts

22
Q

what is lactose intolerant?

A

can’t drink or eat certain things and can’t break down lactose without lactase

23
Q

what does denatured mean?

A

becomes distorted and cannot bind its substate

24
Q

what are the 5 ways to change the rate of a chemical reaction?

A

temperature, pH, substrate concentration, catalysts, or competitive inhibitor

25
Q

temperature of a chemical reaction

A

increasing temperature increases the rate of reaction; molecules are moving faster

26
Q

pH in a chemical reaction

A

how acidic a solution is; most enzymes only work at very specific pH

27
Q

substrate concentration in a chemical reaction

A

the higher the amount of substrate, the faster the reaction

28
Q

catalysts in chemical reaction

A

speeds up reaction

29
Q

competitive inhibitor in chemical reactions

A

slows down reactions, opposite of catalysts

30
Q

when does the energy from ATP come from?

A

carbohydrates, lipids, and proteins

31
Q

carbohydrates

A

most commonly broken down for ATP

32
Q

lipids

A

broken down after carbs

33
Q

proteins

A

least likely to be broken down for energy

34
Q

how to make ATP?

A

cells must join together ADP and a phosphate using energy from food

35
Q

when atp is broken down, does it release or absorb energy?

A

release

36
Q

what is the structure of ATP?

A

nitrogen base, sugar ring, and 3 phosphate groups

37
Q

true or false: atp is changed back into adp when a phosphate

A

false

38
Q

is adp or atp recycled?

A

adp

39
Q

what is chemiosmosis

A

movement of ions down a concentration gradient

40
Q

what is ATP synthase?

A

used to add the 3rd phosphate to ADP to make ATP, using energy from the food you eat

41
Q

How do dehydration synthesis and hydrolysis interact with ATP?

A

Dehydration synthesis is defined as the construction of monomers into polymers. Hydrolysis is the breakdown of polymers into monomers. An example of this would be lactose is broken down into glucose (hydrolysis). ATP is the result of cellular respiration, which is an exothermic reaction.

42
Q

What is a eukaryote?

A

A cell with membranes and organelles

43
Q

What is a prokaryote?

A

They are cells that lack membranes or organelles.
