cell respiration flashcards

Question 1

overall formula for cellular respiration

Answer 1

C6H12O6 + 6O2 -> CO2 + H2O + ATP

Question 2

reactants of cellular respiration

Answer 2

Glucose and Oxygen

Question 3

products of cellular respiration

Answer 3

Carbon dioxide, water, and ATP

Question 4

What happens in process of glycolysis

Answer 4

glucose is split into pyruvic acid producing small amounts of NADH and ATP

Question 5

is glycolysis anaerobic or aerobic

Answer 5

anaerobic

Question 6

where does glycolysis occur

Answer 6

cytoplasm

Question 7

how efficient is glycolysis

Answer 7

not a very efficient process

Question 8

what is the net gain of ATP

Answer 8

2% gain

Question 9

After glycolysis if O2 is not present, which process will occur next

Answer 9

fermentation

Question 10

The 2 types of fermentation

Answer 10

Lactic Acid and Alcoholic

Question 11

How are the 2 types of fermentation different

Answer 11

Lactic acid fermentation makes lactic acid and alcoholic fermentation makes ethanol and carbon dioxide

Question 12

why does fermentation occur if no atp is produced

Answer 12

it uses other forms of energy in the process of glycolysis

Question 13

what are the uses of Alcholic fermentation in the kitchen

Answer 13

yeast

Question 14

Where does krebs cycle occur

Answer 14

Matrix

Question 15

Where does the ETC occur

Answer 15

Matrix

Question 16

what determines if a cell goes through fermentation or cellular respiration

Answer 16

oxygen

Question 17

What is the intermediate molecule that goes into the krebs cycle

Answer 17

Acetyl CoA

Question 18

what is the main point of the Krebs Cycle

Answer 18

Create NADH and FADH

Question 19

Why is the Krebs cycle also called the Citric Acid Cycle

Answer 19

It is the first product formed in the cycle

Question 20

What happens during the ETC

Answer 20

The etc will take the H off of NADH and FADH2, and turn them back into NAD and FAD

Question 21

Why do we need oxygen

Answer 21

To breathe

Question 22

What is the efficency of the ETC

Answer 22

39%

Question 23

What is O2 debt

Answer 23

when someone consumes oxygen at a faster rate than it can be replaced, leading to a deficit in O2 which cause increased respiration as the body attempts to replace the used oxygen

Question 24

How long does it take to use up all the glucose in our blood stream

Answer 24

20 minutes

Question 25

Then what do we start doing for energy

Answer 25

metabolizing fats into 9 pyruvic acid

Question 26

How is cellular respiration and photosynthesis closely linked

Answer 26

photosynthesis makes glucose which is used in cellular respiration for making ATP

Question 27

why is oxygen needed in cellular respiration

Answer 27

pyruvic acid is broken down and NADH is used to make large amounts of ATP

Question 28

What is ATP synthase

Answer 28

enzyme that synthesizes ATP in the mitochondrial inner membrane

Question 29

What is chemiosmosis

Answer 29

the movement of ions across semipermeable membrane bound structure

Question 30

What is the Function of NADH & FADH2?

Answer 30

Carry their electrons to the ETC
