KA7- Cellular Respiration

Question 1

Glycolysis

Answer 1

the breakdown of glucose to pyruvate in the cytoplasm
No oxygen required
2 stages

Question 2

ATP synthesis

Answer 2

electrons are passed along the electron transport chain releasing energy

Question 3

ATP

Answer 3

used to transfer energy to cellular processes which require energy
ATP—>ADP+Pi releases energy

Question 4

ATP in glycolysis

Answer 4

required for the phosphorylation of glucose and intermediates during the energy investment phase of glycolysis
This leads to the generation of more ATP during the energy pay-off stage and results in a net gain of ATP

Question 5

Stage 1 glycolysis

Answer 5

Energy investment phase
2 ATP phosphorylate glucose and intermediates

Question 6

Stage 2 glycolysis

Answer 6

Energy pay off stage
4 ATP produced causing net gain of 2 ATP per glucose molecule
Hydrogen ions and electrons released from intermediates
Passed onto the coenzyme NAD to form NADH

Question 7

Regeneration of ATP from ADP

Answer 7

Uses the energy released from cellular respiration

Question 8

Glycolysis product

Answer 8

Pyruvate

Question 9

CAC product

Answer 9

Carbon dioxide

Question 10

ETC product

Answer 10

Water

Question 11

Glycolysis raw materials

Answer 11

Glucose

Question 12

CAC raw materials

Answer 12

Pyruvate
Acetyl

Question 13

ETC raw materials

Answer 13

Hydrogen ions
Electrons
Oxygen

Question 14

Fermentation

Answer 14

breakdown of pyruvate to lactate the absence of oxygen after glycolysis
