21
Q

In ATP production, how many ATP molecules are used to get glycolysis started?

A

2

22
Q

in NADH production, what is passed to the electron carriers NAD+ ?

A

4 high energy electrons

23
Q

What happens when pyruvic acid is formed?

A

one molecule of glucose C6H12O6 bonds are broken

24
Q

What are the advantages of glycolysis?

A

produces 2 ATP, 2 NADH, and 2 pyruvic acid

25
Q

pyruvic acid is broken down into CO2 in a series of energy extracting steps. OXYGEN HAS TO BE PRESENT

A

Krebs Cycle

26
Q

What is the use of CO2 when produced by the Krebs Cycle?

A

CO2 is exhaled

27
Q

When in the presence of oxygen, the electrons in NADH do what?

A

generate huge amounts of ATP

28
Q

In the ETC, electrons are passed down the chain transporting what across the membrane and it creates a NEGATIVE region called what?

A

H+ ions; chemiosmosis

29
Q

Every time the electrons in ATP production move, H+ ions move, thus ATP is created by what?

A

ATP synthase

30
Q

As each pair of electrons from NADH moves down the length of the ETC ___ molecules of ATP are produced and __ molecules of FADH2 are produced

A

3;2

31
Q

ATP = __% TOTAL energy in glucose
__ from the Krebs Cycle; and __ from the ETC

A

38%; 2; 34

32
Q

Fermentation is what type of respiration?

A

anaerobic

33
Q

What is regenerated so glycolysis can continue?

Q

Alcoholic fermentation produces what?

A

ethyl alcohol and CO2

36
Q

Alcoholic fermentation does what?
