Cellular Respiration & Photosynthesis

Question 1

Compare and contrast aerobic and anaerobic respiration

Answer 1

Aerobic Respiration uses oxygen and yields many more ATP molecules. It is he process in which our cells break down food and turn it into energy. Anaerobic Respiration does not use oxygen and yields only 2 ATP molecules. Both processes include glycolysis.

Question 2

Aerobic Respiration

Answer 2

Uses oxygen

Question 3

What is the first step of cellular respiration?

Answer 3

Glycolysis

Question 4

Electron Transport Chain

Answer 4

Where most ATP production occurs. Occurs on the inner membrane of the mitochondria. All of the electrons (H) from glucose travel to the inner membrane of the mitochondria.

Question 5

How many ATP are produced by the Kreb cycle for each molecule of glucose?

Answer 5

2

Question 6

Which of the part of the cellular respiration process takes place in the cytoplasm?

Answer 6

Glycolysis

Question 7

In what organelle would you find Kreb’s cycle and the electron transport chain?

Answer 7

The Mitochondria

Question 8

What is the main event that occurs in glycolysis?

Answer 8

This process breaks glucose into pyruvate molecules. It produces 2 ATPs for each glucose. NADH is released to be used later

Question 9

How would you describe the electron transport chain?

Answer 9

This process uses energy captured from electrons flowing to oxygen to produce most of the ATPs in cellular respiration. (32-34 net gain)

Question 10

What is needed for aerobic respiration?

Answer 10

Oxygen

Question 11

Which portion of cellular respiration produces the most ATP?

Answer 11

The Electron Transport Chain (32 ATP per glucose)

Question 12

During respiration, the electron transport chain occurs in the….

Answer 12

inner membrane of the mitochondria.

Question 13

Fermentation occurs….?

Answer 13

When oxygen is NOT present in anaerobic cellular respiration.

Question 14

Where does glycolysis occur?

Answer 14

cytoplasm

Question 15

Explain the Kreb Cycle. What happens?

Answer 15

This part of respiration occurs in the matrix of the mitochondria. Remaining carbon from the glucose are oxidized. Releasing carbon dioxide, NADH, FADH2. It releases enough energy to make 2 ATP and 6 CO2.

Question 16

Where does the Kreb Cycle occur?

Answer 16

The matrix of the mitochondria.

Question 17

What is a pyruvate molecule?

Answer 17

1/2 of a glucose molecule.

Question 18

How many pyruvates are produced from ONE glucose molecule?

Answer 18

2

Question 19

How many carbons are in glucose?

Answer 19

6

Question 20

What is the storage form of energy called?

Answer 20

ATP (Adenosine Triphosphate)

Question 21

In which environment does a cell produce more ATP?

Answer 21

Aerobic

Question 22

Steps of Anaerobic Cellular Respiration

Answer 22

Glycolysis, Fermentation

Question 23

Steps of Aerobic Cellular Respiration

Answer 23

Glycolysis, Kreb’s Cycle, Electron Chain Transport

Question 24

Cellular Respiration Formula

Answer 24

C6H12O2 + 6O2 ——> 6CO2 + 6H20 + Energy (ATP)

Question 25

Anaerobic Cellular Respiration occurs in ...

Answer 25

bacteria, yeast, or muscle cells.

Question 26

Products of Aerobic Cellular Respiration

Answer 26

6CO2 +6H2O + Energy (ATP)

Question 27

Reactants of Aerobic Cellular Respiration

Answer 27

C6H12O6 +6O2

Question 28

Definition of Cellular Respiration

Answer 28

The process of breaking the chemical bonds of glucose into energy. Breaking chemical bonds releases electrons.

Question 29

ATP releases energy and becomes....

Answer 29

ADP (Adenosine Diphosphate)

Question 30

What happens in the Prepatory Reaction?

Answer 30

Pyruvates of glycolosis move into the mitochondria converted into Acetyl CoA. More NADH produced. CO2 is released

Question 31

How much ATP is produced from 1 glucose molecule?

Answer 31

36-38 ATP

Question 32

What is Photosynthesis?

Answer 32

Plants capture the energy from the sunlight and use it with qater and carbon dioxide to produce carbohydrates (sugar) and oxygen is also released as a byproduct.

Question 33

Where do reactions of photosynthesis occur?

Answer 33

Chloroplast

Question 34

2 Primary Steps of Photosynthesis

Answer 34

Light Reactions and Calvin Cycle

Question 35

What happens in Light Reactions?

Answer 35

Happens in the Thylakoids, special pigments absorb light energy and transfer it to high energy electrons and produce ATP and NADPH. Water is also split to replace the gih energy electrons and Oxygen is released

Question 36

What happens in Calvin Cycle?

Answer 36

Occur in the Stroma of the Chloroplast, a series of reactions use NADPH and ATP to turn carbon dioxide into carbohydrates. NADP+ and ADP produce by Calvin Cycle are then recycled to be used by the next set of light reactions.
