glycolysis

Question 1

order of the products of glycolysis

Answer 1

glucose 6 phosphate
fructose 6 phosphate
fructose 1,6 bisphosphate
glyceraldehyde 3 phosphate (G3P)
1,3 bisphosphosphoglycerate
3 phosphoglycerate
2 phosphoglycerate
PEP
Pyruvate

Question 2

glycolysis occurs in the

Answer 2

cytoplasm

Question 3

3 phases of glycolysis

Answer 3

energy investment phase, cleavage, energy payoff phase

Question 4

during the energy investment phase, the cell spends

Answer 4

atp

Question 5

this investment is paid off with interest in the energy payoff phase. when ATP is produced by

Answer 5

substrate level phosphorylation

Question 6

net energy from glycolysis

Answer 6

2 ATP, 2 NADH

Question 6

this enzyme transfers a phosphate group from ATP to the sixth carbon of glucose, investing the first ATP

Answer 6

hexokinase

Question 7

the resulting product of glucose 6 phosphate is converted into its isomer fructose 6 phosphate with the enzyme

Answer 7

phosphogluco-isomerase

Question 8

this enzyme transfers a phosphate group from ATP to the first carbon of sugar. this is the second ATP invested. the resulting product will become fructose 1,6-bisphosphate

Answer 8

phosphofructoskinase-1 (PFK-1)

Question 9

this enzyme cleaves the six carbon sugar fructose 1,6 bisphosphate into two different sugars.

Answer 9

aldolase

Question 9

what are the two sugars produced during the cleavage

Answer 9

Dihydroxyacetone (DHAP) and Glyceraldehyde 3-phosphate (G3P)

Question 10

the conversion from DHAP to G3P happens with the enzyme

Answer 10

triose phosphate isomerase

Question 11

the two G3P molecules from step 4 and 5 enter the

Answer 11

energy payoff phase.

Question 12

In step 6, this enzyme will catalyze two sequential reactions.

First, the sugar is oxidized by the transfer of electrons to NAD+ forming NADH.

and second, a phosphate group is attached to the oxidize substrate making a high energy product 1,3-bisphosphoglycerate

Answer 12

triose phosphate dehydrogenase

Question 13

this enzyme transfers a phosphate group from 1,3-bisphosphoglycerate to ADP to produce ATP and 3-phosphoglycerate

Answer 13

phosphoglycerokinase

Question 14

the phosphate group in 3 phosphoglycerate is relocated into its second carbon with the help of the enzyme

Answer 14

phosphoglycerate mutase

Question 15

This enzyme yields phosphoenolpyruvate also called PEP, a compound with a very high potential energy.

Answer 15

enolase

Question 16

In step 10, the last phosphate group is transferred from PEP to ATP, producing two more molecules of ATP with the help of

Answer 16

pyruvate kinase

Question 17

looking at glycolysis alone, we can consider it as an ________ process because we did not use oxygen

Answer 17

anaerobic
