Bio final kaplan slides 6/7 (LO 8)

Question 1

Glycolysis

Answer 1

-Cytoplasm
-Uses 2 ATP to make 2 pyruvates
-2 NADH product
-2 NET ATP product

Question 2

Pyruvate oxidation

Answer 2

-Mitochondrial matrix
-Pyruvate dehydrogenase removes carbon
-Remaining 2 carbon attached to co enzyme A
-Acetyl CoA product
-CO2 product

Question 3

Citric acid cycle

Answer 3

-Mitochondrial matrix

-STEP 1: Acetyl CoA reacts with oxaloacetate and makes citrate
-STEP 8: Malate converted to malate dehydrogenase then regenerates oxaloacetate

CELL UP 4 ATP

Question 4

Electron transport chain

Answer 4

-Mitochondrial inner membrane

-NADH and FADH2 e carriers
-e cause a H+ proton gradient
-H+ through ATP synthase, which makes ATP
-Oxygen final electron acceptor

-Water product
-ATP product

Question 5

Fermentation

Answer 5

-Regenerate NAD+
-Cytosol

-NAD+ used to break down glucose into pyruvate

Question 6

Lactic acid fermentation

Answer 6

-Glucose into pyrucates
-Pyruvates into lactate (e carriers)

-2 NADH into 2 NAD+ product
-2 NET ATP

Question 7

Alcoholic fermentation

Answer 7

-Glucose into pyruvates
-Pyruvate’s into acetaldehydes (e carriers)
-Acetaldehydes into ethanol

-Ethanol waste product
-2 NADH into NAD+ product
-2 NET ATP
