part two

Question 1

what happens to glucose during glycolysis

( ATP, NADH}

Answer 1

6C in glucose gets split into two 3C pyruvate

ATP and NADH is free energy that is released and captured

2 ADP-> 2 ATP ; 2 NAD+ -> 2 NADH

Question 2

what are the 10 stages of glycolysis

Answer 2

• glucose
• glucose 6-phosphate
• fructose 6-phosphate
• fructose 1,6- bisphosphate
• DHAP
• glyceraldehyde 3 phosphate
• 1,3 bisphosphoglycerate
• 3-phosphoglycerate
• 2-phosphoglycerate
• phosphoenolpyruvate
• pyruvate

Question 3

what compound enters the pyruvate oxidation stage

Answer 3

pyruvate

Question 4

what compound enters the citric acid cycle

Answer 4

acetyl-CoA

Question 5

what two compounds combine to form citrate in the citric acid cycle

Answer 5

sulfur containing compound called coenzyme A bonds to acetyl

Question 6

why is oxaloacetate important

Answer 6

it is both a reactant and a product

product of step 8 and a reactant in step 1

Question 7

production of ATP in glycolysis

Answer 7

2 ATP- substrate phosphorylation

Question 8

production of ATP in pyruvate oxidation

Answer 8

0 ATP

Question 9

production of ATP in citric acid cycle

Answer 9

2 ATP- substrate phosphorylation

Question 10

production of ATP in chemiosmosis

Answer 10

32-34 ATP- oxidative phosphorylation

Question 11

in what stage is ATP produced in its highest quality and what type of phosphorylation is this?

Answer 11

chemiosmosis; 36-38 ATP; oxidative phosphorylation

Question 12

what are the products of ETC/chemiosmosis

Answer 12

32-34 ATP and 6H2O

Question 13

where does the energy come from during ATP production in chemiosmosis

Answer 13

the proton motive force makes proteins (H+) because of a electrochemical gradient acros the membrane, cells use this to do work
