Q

Process of glycolysis:

A
  • Glucose is broken down in the cytoplasm through the process of glycolysis
  • Two molecules of ATP are used to break down glucose
  • Four ATP and two NADH is produced for each molecule of glucose that is broken down. End product is two Pyruvates

Q

Krebs Cycle

A

Pyruvate releases co2 making NADH producing acetyl CoA. CoA bonds with the 4 carbon compound. Making 6 carbon (citric acid). Loses another co2 Making another NADH, becomes a 5 carbon. Loses another Co2 making NADH, becomes a 4 carbon. Then make FADH2. Charged with atp. Makes NADH. You are left with the 4 carbon compound that will continue the cycle.

Q

Final step of cellular respiration in the membrane

A
  • Hydrogen from NADH release e-
  • H+ are pumped outside matrix and accumulate and go through ATP synthase
  • E- to membrane to travel down chain giving up energy to produce ATP
  • Used e- is then reunited with P+ forming H
  • Two H combine with O water is produced (H2O)
17
Q

Why do we need oxygen?

A

Oxygen picks up hydrogen, allows the transport chain to run, makes ATP so we can continue to live

18
Q

What makes the ATP?

A

Energy from the electron

19
Q

ATP TOTALS:

Glycolysis

A

(2 ATP net) produces 4 ATP and 2 NADH

20
Q

ATP TOTALS:

Krebs

A

2 ATP, 8NADH, 2FADH2

21
Q

ATP TOTALS:

Electron transport

A

24 ATP from multiplying the 8NADH from the Krebs cycle x3

22
Q

ATP TOTALS:

Extra info to know:

A

Each NADH = 2 ATP

Each group of 3 FADH2 = 2ATP (only 2 produced so not a factor figured into total below)

23
Q

ATP TOTAL:

A

36 ATP from one molecule of glucose

24
Q

Anaerobic

A

Anti oxygen

25
Q

Anaerobic respiration

A

anaerobic pathway that follows glycolysis

26
Q

Lactic acid fermentation

A

After glycolysis the needed Oxygen is not available so fermentation takes place

27
Q

What’s the difference between pyruvate and lactic acid?

A

Lactic acid is charged with an electron

28
Q

Alcohol fermentation

A

After glycolysis in yeasts and some bacteria alcoholic fermentation takes place

29
Q

What is alcoholic fermentation used to produce?

A

Bread, fuel, beverages

30
Q

How many ATP can one NDAH make?

A

3

31
Q

What is the difference between alcoholic fermentation and pyruvate.

A

The alcoholic fermentation makes carbon dioxide and ethanol.
