Exam 3

Question 1

ADP ALWAYS LOW ATP ALWAYS HIGH

Question 2

ATP WANTS TO BECOME ADP TO BECOME BALANCED - high to low diffusion

Answer 2

If ever balanced tho ur dead - thermodynamically favorable
going from low to high unfavorable (ice cube and slide)

Question 3

Hydrolysis to break apart glucose to glucose-6-phosphate

Answer 3

reaction is unfavorable not spontanous not on its own - requires a ton of energy

Question 4

glucose to glucose-6-phosphate and atp to adp is couple reaction

Answer 4

glucose reaction cannot occur without the atp reaction

Question 5

glucose must go through glut 4 to get into the cell

Question 6

hexokinase reaction- cells trapping glucose inside the cell

Question 7

regulatory step of glycolysis - requires energy input

Question 8

once it is glucose 6 phosphate it cannot be allowed inside so GLUT 4 (bouncer) kicks it out

Question 9

phosphofructokinase - gatekeeper of glycolysis (determines if we proceed w glycolysis or not)

Question 10

anabolic - create stuff - needs energy
catabolic - break stuff - releases energy

Answer 10

breaking a plate is easy but buildingone is hard

Question 11

CYTOSOL IS WHERE GLYCOLYSIS OCCURS

Answer 11

ANAROEBIC

Question 12

MITOCHONDRIA

Answer 12

KREBS CYCLE, AEROBIC, ELECTRON TRANSPORT CHAIN (OXIDATIVE PHOSPHORALATION) , ENERGY METABOLISM

Question 13

release tremendous amount of energy when break bond between gamma and beta phosphate

Question 14

magnesium is present with every atp to stabilize the atp —> mg 2+ stabilizes negative beta and negative gamma phosphates

Question 15

cross out ATP DURING CATABOLISM AND ANABOLISM SLIDE

Question 16

enzymes lower the activation energy required for these reactions to proceed

Answer 16

lighting a fire is easier with gasoline than without - makes it faster

Question 17

Coenzymes will interact with the enzyme, organic so they contain carbon

Answer 17

NAD+ (active form of vitamin b3) to NADH: Nicotin Aminde adanine dinucleotide llook up the name
Nicotin –> niocin –> vitamin B3

Question 18

Why do energy drinks have a lot of vitamin b12 – so niacin can turn into NAD+

Question 19

FAD/FADH2 –> active form of vitamin b2

Answer 19

flavinine – look up what it stands for and its an active form of riboflavin

Question 20

dont want glucose to escape so give a phosphate hat and it has to go into the club

Question 21

6 carbon glucose

Question 22

2 pyruvate molecules for every 3 glucose molecules

Answer 22

then turn pyruvate into acetylcoa (acetylCoA is the universal coA but all proteins, fats, and carbs all turn into those) REQUIRES OXYGEN TO TURN PYRUVATE INTO ACETYL COA

Question 23

ACETYL COA IS FUEL FOR THE KREBS CYCLE
