Krebs Cycle And Electron Transport

Question 1

Glycolysis is the process of converting

Answer 1

Glucose to pyruvate

Question 2

Glycolysis is done when there is no readily available/ inadequate

Answer 2

Oxygen

Question 3

Anaerobic metabolism glycolysis produces how many ATP atoms

Answer 3

2

Question 4

Aerobic metabolism glycolysis produces how many ATP atoms

Answer 4

30-32 ATP

Question 5

Aerobic metabolism consists of which stages

Answer 5

Glycolysis
Krebs cycle
Electron transport chain
Oxidative phosphorylation

Question 6

Krebs cycle begins when pyruvate from glycolysis enters

Answer 6

Mitochondrial matrix

Question 7

How many cycles does the Krebs cycle go through per glucose molecule?

Answer 7

2 cycles producing 2x ATP

Question 8

The electrons of hydrogen atoms produced in which step of aerobic metabolism enter the electron transport chain?

Answer 8

Electrons of hydrogens from Krebs cycle

Question 9

Oxidative phosphorylation and electron transport chain step 1

Answer 9

Energy is released during metabolism and is captured by high energy electrons carried by FADH2 and NADH

Question 10

Oxidative phosphorylation and electron transport chain step 2

Answer 10

Energy from high energy electrons move along ETC and pumps H+ from the mitochondria matrix into inter-membrane space

Question 11

Oxidative phosphorylation and electron transport chain step 3

Answer 11

Electrons at end of the electron transport system are back to normal state, combining with H+ and O2 to from H2O

Question 12

Oxidative phosphorylation and electron transport chain step 4

Answer 12

Potential energy captured in the H+ concentration gradient is converted to kinetic energy when H passes through ATP synthase.

Question 13

What’s the point of oxidative phosphorylation and electron transport chain

Answer 13

To provide energy to phosphorylation ADP to ATP
