Question 19

What is the purpose of the Krebs Cycle?

Answer 19

To make FADH2, NADH, and a little ATP

Question 20

What is the purpose of pyruvate conversion?

Answer 20

To go to the Krebs Cycle

Question 21

What is the purpose of Glycolysis?

Answer 21

To break down glucose into Pyruvate, generate energy in the form of ATP, and make NADP which are all used in the next other steps of cellular respiration

Question 22

Electron Transport Chain Location

Answer 22

-inner Membrane

Question 23

Reactants of ETC

Answer 23

• O2
• 2 FADH2

-10 NADH

-ADP

Question 24

Products of ETC

Answer 24

• H2O

-34 ATP

Question 25

What is the main purpose of the ETC?

Answer 25

To make ATP

Question 26

Describe the role of oxygen in the ETC

Answer 26

It's role is to pull the electrons off the ETC and to bind it with H+ ions to make water

Question 27

What happens in Glycolysis?

Answer 27

- Glucose is broken down into Pyruvate - 2 ATP molecules are formed (net gain) - 2 NADH are formed

Question 28

What happens in the Kreb's Cycle

Answer 28

-Many electrons carriers a re formed: 6 NADH and 2 FADH2 - 2 ATP molecules are formed -Waste product CO2 is formed

Question 30

What happens in the ETC

Answer 30

- Electrons from NADH and FADH2 are dropped off and help power the production of ATP - 32 ATP molecules are formed -Water is formed

Question 31

Cellular Respiration

Answer 31

The process that releases energy from food in the presence of oxygen

Question 32

_______ makes cellular respiration possible

Answer 32

Oxygen

Question 33

How do you know how many times the Kreb Cycle cycles?

Answer 33

By the amount of Acetyl CoA

Question 34

How do heterotrophs get energy?

Answer 34

They get energy from consuming autotrophs which they rely on to get energy from since they cannot make their own food

Question 34

How do organisms generate energy when oxygen is not available

Answer 34

-Organisms go through the process of Fermentation (lactic acid or alcoholic) which creates NAD+ as a product allowing Glycolysis to continue (allows cells to produce ATP when there is no oxygen)
