enzymes

Question 1

what is an enzyme?

Answer 1

a protein that speeds up chemical reaction
- important because chemical reactions occur constaintly

Question 2

what is a chemical reaction

Answer 2

breaking and creating of bonds between diffrent substances

Question 3

what is activation energy

Answer 3

energy needed too start chemical reaction
-ex. pushing a rock up hill for it to fall on its own down

Question 4

what are reactants

Answer 4

substance CHANGED during chemical reaction

Question 5

what is the product

Answer 5

what we get out of it

Question 6

enzymes are _____ meaning they _________ reactions by reducing activation energy requiared to start the reaction

Answer 6

catalysts, speed up

Question 7

what is the first step Enzymes create the right conditions for a reaction to occur

Answer 7

reactant ( called a substrate) binds to a special part of the enzyme called an ACTIVE SITE

Question 8

what is the 2nd step Enzymes create the right conditions for a reaction to occur

Answer 8

reaction takes place ( making or breaking bond)

Question 9

what is the 3rd step Enzymes create the right conditions for a reaction to occur

Answer 9

product realsed from the enzyme + reamins unchanged

Question 10

T or F: enzymes have a unique structure that only fits 1 substance

Answer 10

true
- they fit toghter like a key and a locke
- enzyme shape is essintiol to its functiojn

Question 11

what is denatruation

Answer 11

when the enviormental condtioions cause enzyme to lose its shape and no longer work.

Question 12

what are the 4 ways to change rate of reaction

Answer 12

• temparture : will increase or decrease rate of reaction
• pH levels : how acidic or basic solution is
• reactant concentration : increase amount, rate of reaction increases
• catalysts : like enzyems speed up rate of reation
