Glucose + Oxygen = Carbon Dioxide + Water + Energy

Question 6

Stages of Cellular Respiration (in order)

Answer 6

Glycolysis
The Krebs Cycle
Electron Transport Chain

Question 7

Answer 7

Pathways that require oxygen. (in air)

Question 8

What Stages of Cellular Respiration are Aerobic

Answer 8

The Krebs Cycle
The Electron Transport Chain

Question 9

Answer 9

Pathways that do not require oxygen.
(without air)

Question 10

What processes are Anaerobic

Answer 10

Glycolysis
Fermentation

Question 11

Glycolysis takes place in the

Answer 11

cytoplasm of the cell

Question 12

Krebs and ETC takes place inside the

Answer 12

mitochondria

Question 13

What Happens to Energy in Photosynthesis

Answer 13

It Deposites energy in the bonds of glucose

Question 14

What happens to Energy in Cellular Respiration

Answer 14

It withdraws energy by breaking the bonds

Question 15

What happens to Carbon Dioxide in Photosynthesis

Answer 15

removes it from the atmosphere

Question 16

What happens to Carbon Dioxide in Cellular Respiration

Answer 16

puts it back into the atmosphere

Question 17

What happens to Oxygen in Photosynthesis

Answer 17

releases it into the atmosphere

Question 18

What happens to Oxyegn in Cellular Respiration

Answer 18

Takes it in from the atmosphere to release energy from food

Question 19

Glycolysis

Answer 19

Glucose is transformed into pyruvic acid

Question 20

In Glycolysis what is the ATP production

Answer 20

It has an investment of 2, produces 4, and a net gain of 2 ATP per molecule of glucose.

Question 21

In Glycolysis what happens in NADH production

Answer 21

Four high-energy electrons are passed to the electron carriers NAD+. This creates NADH. NADH carries the electrons to the Electron Transport Chain

Question 22

how is Pyruvic acid formed?

Answer 22

1 molecule of glucose C6H12O6 bonds are broken. The bonds are rearranged and 2 molecules of pyruvic acid (a three-carbon compound) are formed.

Question 23

What are the Products of Glycolysis

Answer 23

2 ATP, 2 NADH, and 2 pyruvic acid.

Question 24

the Krebs Cycle

Answer 24

Pyruvic acid is broken down into carbon dioxide in a series of energy-extracting steps. Oxygen has to be present.

Question 25

How are the products of the Krebs Cycle used?

Answer 25

CO2 is exhaled and The electrons in NADH, when in the presence of oxygen, generate huge amounts of ATP.

Question 26

What happens in Electron Transport

Answer 26

The electrons are passed down the chain transporting H+ ions across the membrane and creates a negative (chemiosmosis) region.

Question 27

Every time the electrons move, H+ ions move so

Answer 27

thus ATP is created by ATP synthase.

Question 28

As each pair of electrons from NADH moves down the length of the ETC _ molecules of ATP are produced and 2 for FADH2

Answer 28

3

Question 29

Total ATP created per 1 glucose molecule in cellular respiration

Answer 29

2 from glycolysis 2 from Krebs Cycle 34 from Electron Transport Chain

Question 30

what percent of Total energy in glucose is ATP

Answer 30

38%

Question 31

Fermentation is what

Answer 31

Anaerobic Respiration

Question 32

What are the forms of Fermentation?

Answer 32

Alcoholic Fermentation Lactic Acid Fermentation

Question 33

what is regenerated so glycolysis can continue

Answer 33

NAD+

Question 34

Alcoholic Fermentation produces what

Answer 34

Produces ethyl alcohol and carbon dioxide.

Question 35

What does Alcoholic Fermentation do

Answer 35

Causes bread to rise and creates alcohol for beverages

Question 36

What is Lactic Fermentation used for

Answer 36
