What is cellular respiration

The process of breaking down glucose to release energy and form molecules of ATP

1

What is the complete balanced equation for respiration

C6H12O6->6CO2+6H2O+energy(ATP)

2

What is the C6 molecule initially broken down into?

Pyruvate

3

Does this breakdown require oxygen

No

4

What does anaerobic mean?

Without presence of O2 (oxygen)

5

What is glycolysis? Where does it occur

"Glucose breaking" , cytoplasm

6

Besides pyruvic acid, what does glycolysis produce

2 ATP and 2 NADH

7

How many ATPs are formed in glycolysis

2

8

After glycolysis, how many steps are involved in aerobic respiration?

2

9

Where does the aerobic stage of respiration take place

Mitochondria

10

What are the steps in aerobic respiration

Krebs cycle
Electron transport chain

11

What is another name for the Krebs cycle

Citric acid cycle

12

Who was it named for

Hans Krebs

13

What is released as a waste product in the Krebs cycle

CO2

14

What is the electron transport chain

NADH and FADH formed in the Krebs cycle move from the matrix of mitochondria to the inner membrane called cristae, also called oxidative phosphorylation

15

Where are the molecules of the electron transport chain located

Cristae

16

What is the final electron acceptor in the chain

Oxygen

17

When oxygen accepts the electrons, what is formed?

Water

18

What 2 compounds so you exhale ? In what processes(be specific) are these products produced?

CO2 (Krebs Cycle), water (ETC)

19

What is the total number of ATPs that can be formed from the breakdown of one glucose molecule

38 ATP

20

What are 3 end products of cellular respiration in what processes are each product produced

NADH (Krebs Cycle), FADH2 (Krebs cycle) ATP (Krebs cycle and ETC)

21

At the end of glycolysis, if no oxygen is present to break down pyruvic acid, what can happen

Fermentation (alcoholic or lactic acid)

22

Name the two major types of fermentation, how many ATPs are formed in fermentation

Alcoholic and lactic acid, 2ATP

23

Where does lactic acid fermentation take place ( what type of cells)

Animal cells

24

What organisms carry out alcoholic fermentation

Bacteria, fungi, and yeast

25

What are the end products of alcoholic fermentation

Alcohol, CO2, and NAD+

26

We use fermentation to make what food/drink items?

Alcohol and yeast (bread)

27

What % of energy is lost if a cell goes through fermentation

98%

28

Whig is the source of bubbles in an alcoholic beverage?

CO2, it means fermentation is taking place

29

What are NADH and FADH2

Organic carrier molecules
