Question 20

catabolic/ Hydrolysis reaction

Answer 20

breaks down large molecules

Question 21

Anabolic/synthesis reaction

Answer 21

Building new compounds

Question 22

enezyms

Answer 22

are catalysts meaning that they speed up chemical reactions . They speed of chemical reaction my lowerd the activation energy. They do not get used up in reaction and are very spcific to each cell.

Question 23

substrate

Answer 23

thing that binds with enzyme

Question 24

enzyme- substrate complex

Answer 24

when the substrate temporaily fits inot the enzyme

Question 25

prosuct

Answer 25

the end result of the reaction

Question 26

active site

Answer 26

the area where the substrate fits

Question 27

lock and key model

Answer 27

the substrate fits perfectly into the active site

Question 28

induced fit model

Answer 28

when substrate bids with enzyme and makes subtle changes to active site. the change is the induced fit.

Question 29

enzymes can be affected by

Answer 29

temperature, PH, and concentration

Question 30

denatured

Answer 30

when the enzyme loose the shape of the active site

Question 31

temperature and enzyems

Answer 31

- low temps cause low colossions wich create reactions - High temps will increase collions but too high will amke enzyme denatured.

Question 32

pH and enzymes

Answer 32

they wokr best in naturl ph naturl is 7

Question 33

competive inhibiton

Answer 33

the CI is in the active site not allowing the substrate to lock so the change does not occur

Question 34

non-competitive inhibition

Answer 34

when a molecue binds with an enzyme some place else other than the active site however this changes the shape of the active site so the change does not occur.

Question 35

virus

Answer 35

- are not living because - reproduce only wiht host, no growth and development, does not metabolize, and des not have a response to environment.
