Captures energy from sunlight to make sugars

Answer 9

Photosynthesis

Question 10

A molecule that absorbs light energy

Answer 10

Chlorophyll

Question 11

Where is chlorophyll found?

Answer 11

In the chloroplasts. It is in the thylakoid

Question 12

When would an organism perform chemosynthesis?

Answer 12

An organism that does not get sunlight performs chemosynthesis

Question 13

What is chemosynthesis?

Answer 13

Chemical energy is used to build carbon-based molecules. Used chemical energy instead of light energy

Question 14

Where does photosynthesis occur?

Answer 14

In the chloroplast

Question 15

What two parts of the chloroplast does photosynthesis occur in?

Answer 15

grana- stacks of thylakoids

stroma- fluid portion

Question 16

What is the equation for photosynthesis?

Answer 16

6CO2 + 6h20 —–>(sunlight) C6H12O6 + 6O2

Question 17

What are the reactants of photosynthesis?

Answer 17

CO2 (enters in stomata) and H2O (absorbed through roots; capillary action)

Question 18

What are the products of photosynthesis?

Answer 18

Glucose and oxygen

Question 19

Colors range from red to violet

Accessory pigments

Answer 23

Caretenoids

Question 24

Use energy from sunlight to produce ATP; takes place in the thylakoids

Answer 24

Light dependent reaction

Question 25

No light required; sugar is produced from carbon dioxide; takes place in stroma

Answer 25

Light independent reaction

Question 26

Uses energy stored in sugar to make ATP; occurs in mitochondria

Answer 26

Cellular respiration

Question 27

Where does cellular respiration occur?

Answer 27

In the mitochondria

Question 28

What are the reactants of cellular respiration?

Answer 28

Glucose, oxygen (O2)

Question 30

What is the equation for cellular respiration?

Answer 30

C6H12O6 + 6O2 ——-> 6CO2 + 6H20 + ATP

Question 31

What does aero mean?

Answer 31

requires oxygen

Question 32

What are the 3 stages of aerobic respiration?

Answer 32

Gylcolysis, Kreb’s Cycle, Electron Transport Chain

Question 33

What is glycolysis? Where does it occur? How much ATP does it produce?

Answer 33

Occurs in the cytoplasm; glucose is broken down into 2 pyruvate (2 3 carbon molecules); produces 2 ATP; does not require oxygen

Question 34

What is the Kreb’s Cycle? Where does it occur? How much ATP does it produce?

Answer 34

Occurs in mitochondria; biochemical reactions to breakdown Acetyl CoA (enzyme)- produces CO2, H, and 2 ATP

Question 35

What is the electron transport chain? Where does it occur? How much ATP does it produce?

Answer 35

Occurs in the inner membrane of mitochondria; oxygen is used; water is given off; created 34 ATP

Question 36

The _____ in photosynthesis are the same as the _____ of cellular respiration

Answer 36

reactants - products

Question 37

Compare and contrast photosynthesis and cellular respiration

Answer 37

Photosynthesis- energy capture, happens in chloroplast, reactants are carbon dioxide and water, products glucose and oxygen
Cellular Respiration- energy release, happens in mitochondria, reactants are glucose and oxygen, products are carbon dioxide and water.

Question 38

What is fermentation?

Answer 38

Anaerobic process that allows glycolysis to continue making ATP when oxygen is unavailable

Question 39
