Answer 14

NAD+

Question 15

What’s the reduced form of the electron acceptor in glycolysis

Pyruvate, ATP and NADH

Question 17

What is one of the substrates in substrate level phosphorylation derived from

Answer 17

The breakdown of glucose in glycolysis

Question 18

During substrate level phosphorylation a bond must between what must be broken before ATP can form

Answer 18

Between an organic molecule and phosphate

Question 19

What is required for substrate level phosphorylation to occur

Answer 19

An enzyme

Question 20

How many carbons are in pyruvate, Acetyl coA, and what occurs as a result

Answer 20

Pyruvate = 3 carbon
Acetyl coA = 2 carbon
1 molecule of CO2 is released

Question 21

Answer 21

6

Question 22

In Acetyl coA formation and citric acid cycle, what are the redox reactions involving pyruvate NAD+ and FAD

Answer 22

Pyruvate is oxidized to CO2
NAD+ is reduced to NAD
FAD+ is reduced to FADH2

Question 23

It is easier to remove electrons and produce CO2 from which compounds than which

Answer 23

Compound w three or more C than 2C like coA

Question 24

In mitochondrial electron transport what is the direct role of O2

Answer 24

to function as the final electron acceptor in the ETC

Question 25

What is the final electron acceptor for cellular respiration

Answer 25

Oxygen

Question 26

If there was no O2 during oxidative phosphorylation how would that affect the rate of electron transport and ATP synthesis

Answer 26

Electron transport and ATP would stop

Question 27

Why is more ATP made per molecule of NADH than per molecule of FADH2

Answer 27

Fewer protons are pumped across the inner mitochondrial membrane when FADH2 is the electron donor than when NADH is the electron donor

Question 28

When fermentation must be used, what would happen to the cell's rate of glucose utilization

Answer 28

It would increase a lot

Question 29

If there is no oxygen why does conversion of pyruvate to Acetyl coA stop

Answer 29

In the absence of oxygen electron transport stops. NADH is no longer converted to NAD+ which is needed for the first 3 stages of cellular respiration
