Cellular Respiration Quiz

Question 1

ATP

Answer 1

Adenosine Triphosphate

Question 2

CR equation

Answer 2

glucose + 6O2 –> —> —> 6CO2 + 6H2O + ATP

Question 3

max ATP CR can produce

Answer 3

38 ATP

Question 4

is glycolysis aerobic or anaerobic?

Answer 4

anaerobic

Question 5

where does glycolysis take place?

Answer 5

cytoplasm

Question 6

1 glucose forms how many pyruvate in glycolysis?

Answer 6

2 pyruvate

Question 7

how much ATP and NAD+ produced in glycolysis?

Answer 7

2 ATP and 2 NAD+ (coenzyme)

Question 8

Where is krebs cycle?

Answer 8

mitochondrial matrix

Question 9

pyruvate is ______ to be converted to acetic acid

Answer 9

oxidized - remove oxygen in form of CO2

Question 10

How does NAD+ become NADH?

Answer 10

when bonds of pyruvic acid are broken, the electrons are donated to it and it becomes NADH

Question 11

acetic acid + _____ = Acetyl-CoA

Answer 11

coenzyme A

Question 12

is krebs cycle aerobic or anaerobic?

Answer 12

aerobic

Question 13

yield of krebs cycle

Answer 13

2 ATP, 6 NADH, 2 FADH2 (coenzyme)

Question 14

input of krebs cycle

Answer 14

Acetyl CoA

Question 15

what is released during krebs cycle?

Answer 15

4 CO2

Question 16

ETC location

Answer 16

inner mitochondrial membrane

Question 17

is ETC aerobic or anaerobic?

Answer 17

aerobic

Question 18

Does NADH or FADH2 produce more ATP?

Answer 18

NADH- electrons are dropped off earlier in the ETC

Question 19

what pulls electrons down the ETC

Answer 19

oxygen

Question 20

what is the energy released during the “fall” of electrons used for?

Answer 20

pumping hydrogen ions across the membrane (creates gradient)

Question 21

how is ATP formed?

Answer 21

Hydrogen ions moving from high to low concentration thru enzyme ATP synth. create ATP from ADP by adding a phosphate

Question 22

chemiosmosis

Answer 22

protons travel down electrochemical gradient thru ATP synth. —> ATP

Question 23

what is the FINAL electron acceptor?

Answer 23

oxygen

Question 24

oxygen combines with two hydrogens to make…

Answer 24

6 water (H2O)

Question 25

range of ATP made/glucose

Answer 25

30-38

Question 26

substrate level phosphorylation

Answer 26

when a phosphate is transferred from a substrate to ADP to form ATP- which also releases energy-
- occurs in glycolysis and krebs cycle
