Flashcards in Enzymes Deck (22):
1

How many tiems can an enzyme repat the smae reaction

several

2

What is a substrate

a reactant

3

What do enzymes do to activation energy? How are they able to do this?

 

Lower activation energy by the loss in heat, aka exothermic 

4

What can cause denaturation

high temp.

Diff. pH

Change in Heavy metal and salt consumption

5

Enzymes work like a ___ and___.

Enzymes work like a LOCK and KEY

6

Whats the function and location of DNA Polymerase

Location: Cells w/ a nucleus

Function: MAKE RNA strands

7

what happens when things go wrong

denaturation

8

most enzymes suffixes end in...

-ase

9

define denaturation

change in the shape of a protein. 

if an enzyme's shape changes/becomes denatured it can no longer function the way it's supposed to

10

What are enzymes

Proteins made of amino acid monomers

Known as  catalysts

11

what is activation energy

Min. amount of energy needed to get a reaction started

(Least amount of energy used to have a reaction)

12

what do enzymes do to the rate of chemical reactions

speed up rate of chemical reaction w/o being changed in the reaction

13

WHat is the fuction and location of Pepsin

Location: Stomach

Function: BREAK down protein

14

define Catalyst

Something that speed up the rate of a reaction w/o being chenged by the reation or used up

15

Why are enzymes important

Regulate Chemical Pathways- Ensure that certain chemical reactions happen

Make Material for the Cell: Synthesis & decomposition reactions

Release Energy- Help w/ cellular respiration

Transfer Info.- Help make new cells

16

what happens to catecholase when it becomes denatured

cant react to oxygeb to make polyphenol

17

Enzymes are not consumed or charged in ______ ______.

Enzymes are not consumed or charged in chemical reactions

18

What is the function and location of lactase

Location: Pancreas/digestive juices

Function: BREAK down lactose

19

How do you get the brown stuff off of fruit?

Add lemon juice or salt

20

Catecholase

An enzyme present in most fruits and vegetables, reacts w/ oxygen and cretes polypheonol

21

What is an active site

area on an enzyme where a substance bonds

22

How many reactions can 1 specific enzyme do

Can keep having the same reaction over and over again
