Answer 12

• 2 CO2
• 2 NADH
• -along with 2 Acetoly coe A

Question 13

what molecule is needed for the citric acid cycle to happen

Answer 13

O2

Question 14

what does the citric acid release

Answer 14

4 CO2 from 2 acetyl CoA

Question 15

where in the mitochondria does the citric acid cycle take place?

Answer 15

matrix of mitochondria

Question 16

what happens within the citric acid cycle

Answer 16

• 2 turns produce 6CO2, 4ATP, 10NADH, and 2FADH per glucose
• generates NADH and FADH2

Question 17

2. ethanol

Question 18

what is the equation for ethanol

Answer 18

C2H5OH

Question 19

where does oxidative phosphorylation occur

Answer 19

inner membrane of mitochondria

Question 20

when and where does the substrate level phosphorylation occur

Answer 20

• during glycolysis
• in the citric acid cycle

Question 21

what are some of the functions of substrate level phosphorylation

Answer 21

• synthesize ATP

Question 22

what are the functions of the oxidative phosphorylation

Answer 22

• movement of protons
• procuring ATP based on proton gradient
• makes ATP during cellular respiration
• movement of electrons releases energy that is sued to make ATP

Question 23

what includes the electron transport chain and chemiosmosis

Answer 23

oxidative phosphorylation

Question 24

what is glycolysis

Answer 24

series of reactions that extract energy from glucose by splitting into 2 3 carbon molecules called pyruvates

Question 25

what are the main parts of the mitochondria that deal with cellular respiration

Answer 25

• matrix ( pyruvate processing location)
• inner membrane
• intermembrane space
• outer membrane
• cristae (actual folds)

Question 26

what occurs in the inner mitochondrial membrane

Answer 26

electron transport chain and oxidative phosphorylation

Question 27

when is fermentation used

Answer 27

when something does not have enough oxygen to go through cellular respiration

Question 28

how much ATP is produced from fermentation

Answer 28

2

Question 29

what is the main fucntion of fermentation

Answer 29

provide an alternative pathway to recycle NAD+ from NADH
- electrons from NADH are transferred to pyruvate

Question 30

how many ATP does cellular respiration make

Answer 30

29
