cholesterol

Question 1

cholesterol

Answer 1

lipid found in cell membrane
used to synthesize hormones

Question 2

good cholesterol (HDL)

Answer 2

high density lipoprotein
brings LDL to liver to be broken down

Question 3

bad cholesterol (LDL)

Answer 3

low density lipoprotein
stores cholesterol in bloodstream
forms plaque in arteries

Question 4

trans fat

Answer 4

converts unsatured fat to saturated fat
harder to break down = obesity

Question 5

nucleiec acids

Answer 5

stored in nucleus
composed of nucleotides

Question 6

metabolism

Answer 6

all chemical reactions of the body
body changes food to energy

Question 7

enzymes

Answer 7

add thermal energy to system to increase kinetic energy = reaction occurring

Question 8

what temperatures do enzymes work at

Answer 8

low

Question 9

catalyst

Answer 9

a substance that increases the rate of chemical reactions without become part of product

Question 10

activation energy

Answer 10

energy that must be supplied to cause a rxn

Question 11

lock and key models

Answer 11

enzymes act as keys to lock or unlock substrates

Question 12

substrate

Answer 12

reactants in a enzymatic reaction

Question 13

active site

Answer 13

region on a enzyme where substrates attach

Question 14

Temperature of enzyme activity

Answer 14

Increased temp = increased activity
Declines after certain temp

Question 15

PH of enzyme activity

Answer 15

Had optimum PH
Change in acidity can alter enzyme shape

Question 16

Substrate concentration

Answer 16

Greater number of substrate molecules = greater rate of reaction to a point

Question 17

Competitive inhibitors

Answer 17

Molecules competing for active sites
Bind to enzyme and doesn’t allow production of products

Question 18

Non competitive inhibitors

Answer 18

Chemical binds to a regulatory side causing active site to change shape

Question 19

catabolism

Answer 19

degradation

Question 20

anabolism

Answer 20

synthesis
