enzymes & liver.

Question 1

types of enzymes.

Answer 1

lipase.
protease.

Question 2

what do lipids do?

Answer 2

lipids are broken down into fatty acids.

Question 3

what do protease do?

Answer 3

breaks up proteins.

Question 4

what are the uses of enzymes?

Answer 4

making new substances.
breaking down substances.
speeding up chemical reactions.

Question 5

description of enzymes.

Answer 5

type of protein.
unique number and order of amino acids.-different shaped molecules.
-different functions.

Question 6

what type of catalyst is an enzyme?

Answer 6

biological.

Question 7

examples of where we see them used.

Answer 7

respiration, photosynthesis, digestion.

Question 8

what is a substate?

Answer 8

The molecule or atom that an enzyme acts on.

Question 9

how many steps are there to an enzyme breaking down a substate?

Answer 9

5 steps.

Question 10

what is the first step of breaking down a substate?

Answer 10

substate goes towards enzyme.

Question 11

what is the second step of breaking down a substate?

Answer 11

substate and enzyme connect.

Question 12

what is the third step of breaking down a substate?

Answer 12

substate cracks but doesn’t fully break.

Question 13

what is the fourth step of breaking down a substate?

Answer 13

substate starts to pull away , broken.

Question 14

what is the fifth step of breaking down a substate?

Answer 14

broken pieces of substate pull away.

Question 15

what are the factors that affect enzyme activity?

Answer 15

temperature.
PH balance.
enzyme concentration.

Question 16

why does temperature affect enzyme activity?

Answer 16

an increase in temp above optimal temp causes the active site to become denatured.

Question 17

why does PH balance affect enzyme activity?

Answer 17

deviating from the optimum PH causes the active site to become denatured.

Question 18

why does the enzyme concentration affect enzyme activity?

Answer 18

at a certain point there would be no substrate molecules to react with the enzymes.

Question 19

how the liver works: stage 1.

Answer 19

proteins are broken down by enzymes to form amino acids.

Question 20

how the liver works: stage 2.

Answer 20

amino acids diffuse from a high concentration in your cells to a low concentration in your blood.

Question 21

how the liver works: stage 3.

Answer 21

amino acids travel to the liver in the blood where they will have a higher concentration in the blood than the liver.

Question 22

how the liver works: stage 4.

Answer 22

amino acids diffuse from the blood into the liver.

Question 23

how the liver works: stage 5.

Answer 23

in the liver amino acids are broken down to form area which is then excreted by the kidneys.
