TOPIC 7= CELLULAR RESPIRATION AND FERMENTATION

Question 1

WHAT HAPPENS TO O2 AND GLUCOSE IN CELLULAR RESPIRATION?

Answer 1

O2 GETS REDUCED
GLUCOSE GETS OXIDIZED

Question 2

FERMENTATION?

Answer 2

EXERGONIC, PARTIAL DEGRADTION OF SUGARS THAT OCCURS WITH NO O2

Question 3

AEROBIC RESPIRATION?

Answer 3

OXIDATIVE METABOLISM, USES OXYGEN AND ORGANIC COMPOUNDS

Question 4

ANAROBIC RESPIRATION?

Answer 4

NO O2

Question 5

REDOX REACTION, AGENTS?

Answer 5

ELEC DONOR IS REDUCING AGENT
ELEC RECEPTOR IS OXIDIZING AGENT

Question 6

OXIDATION?

Answer 6

LOSES ELEC

Question 7

REDUCTION?

Answer 7

GAINS ELEC

Question 8

STEPS FOR CELLULAR RESPIRATION AND WHAT THEY DO?

Answer 8

1. GLYCOLISIS= BREAKS DOWN MOLECULES INTO 2 PYRUVATE
2. CITRIC ACID CYCLE= COMPLETES BREAKDOWN OF GLUCOSE
3. OXIDATIVE PHOSPHORYLATION= ACCOUNTS FOR 90% OF ATP MADE

Question 9

OXIDATIVE PHOSPHORLATION?

Answer 9

POWERED BY REDOX REACTIONS

Question 10

SUBSTRATE LEVEL PHOSPHORLATION?

Answer 10

ENZYME TRANSFERS PHOSPHATE GROUP FROM SUBSTRATE TO ADP

Question 11

EACH GLUCOSE MAKES HOW MANY ATP?

Answer 11

ABOUT 32

Question 12

STEPS OF CHEMIOSMOSIS? (5)

Answer 12

1. H GOES DOWN CONC GRADIENT
2. H INTO BINDING SITES, CHANGES SHAPE SO IT SPINS
3. EACH H MAKES ONE SPIN BEFORE LEAVING INTO MATRIX
4. SPINNING OF ROTOR CAUSES INTERNAL ROD TO SPIN
5. CAUSES CATALYTIC SITES IN THE KNOB TO PRODUCE ATP

Question 13

HOW MUCH ENERGY IN GLUCOSE TURNS INTO ATP?

Answer 13

34%

Question 14

WHERE DOES AEROBIC RESPIRATION TAKE PLACE?

Answer 14

CYTOPLASM AND MITOCHONDRIA

Question 15

WHERE DOES ANAROBIC RESPIRATION TAKE PLACE?

Answer 15

ONLY IN CYTOPLASM
