Question 2

Second step?

Answer 2

Acetyl co A

Question 3

Third?

Answer 3

Citric acid cycle/Krebs cycle

Question 4

Fourth?

Answer 4

ETC

Question 5

Where does the glycolysis take place?

Answer 5

Cytoplasm

Question 6

What step doesn’t require o2?

Answer 6

Glycolysis. Also known as fermentation if no O2

Question 7

Point of glycolysis?

Answer 7

Split glucose into many small carbons

Question 8

2 3-carbons form glycolysis also know as

Answer 8

Pyruvates

Question 9

Net yield form glycolysis (4)

Answer 9

2-pyruvates, 2 H2O, 2 ATP, 2 NADH, 2 H+

Question 10

Acetyl CoA occurs where?

Answer 10

On its way to citric acid cycle

Question 11

What happens to Pyruvates in Acetyl coA?

Answer 11

Co enzyme A attaches to Pyruvates to become Acetyl coA, which goes to citric acid cycle from there.

Question 12

Pyruvates become

Answer 12

Acitate

Question 13

Krebs cycle happens where?

Answer 13

Matrix

Question 14

Does it require O2? (Citric acid cycle)

Answer 14

Yes

Question 15

By product of citric acid cycle because of Pyruvates broken down?

Answer 15

CO2

Question 16

The electron carriers created?

Answer 16

NADPH and FADH2.

Question 17

Net yield of Krebs cycle? (3)

Answer 17

2 ATP, 6 NADH, and 2 FADH2.

Question 18

ETC is also known as

Answer 18

Oxidative phosphorylation and chemiosmosis

Question 19

Occurs where?

Answer 19

Inner membrane of mitochondria and across it.

Question 20

Does it require O2?

Answer 20

Yes

Question 21

Oxygen is for what in ETC?

Answer 21

Last electron acceptor (big O)

Question 22

Purpose of ETC and what it accepts?

Answer 22

Accepts NADH and FADH2 and transports THEIR ELECTRONS in and out membrane to produce ATP

Question 23

As Electrons moved in and out inner membrane what is pumped out?

Answer 23

H+ which makes a proton gradient

Question 24

How is ATP produced?

Answer 24

The H+s move across the inner membrane back inside the inner membrane because of the need for equilibrium and use ATP synthase facilitates it and the charge causes the ADP + P in ATP synthase uses the energy to make ATP.

Question 25

What comes out of ETC? (4)

Answer 25

1) ATP
2) H2O
3) NAD+
4)FAD+
