cellular respiration & photosynthesis test

Question 1

 where is food and energy stored

Answer 1

Chemical bonds

Question 2

what is chlorophyll

Answer 2

A green pigment found in chloroplast that absorb light energy

Question 3

what are chloroplast

Answer 3

plant organelles that are found in the leaves

Question 4

what are the reactants of photosynthesis

Answer 4

6co2 + 6h2o + sun

Question 5

what are the products of photosynthesis

Answer 5

c6h12o6 + 6o2

Question 6

what is a light dependent reaction and where does it take place

Answer 6

Solar energy being used to create ATP, takes place in the thylakoids

Question 7

what is the equation for glucose

Answer 7

c6h12o6

Question 8

what are light independent reactions and where do they take place

Answer 8

carbon dioxide is used to produce sugar, no light is required, and it takes place in the stroma

Question 9

What is the function of the stomata

Answer 9

stomata control gas exchange within the leaves

Question 10

Why did the leaves change color in the fall

Answer 10

there is less sunlight meaning less chlorophyll. in this case the carotenoids are used

Question 11

what is cellular respiration

Answer 11

The use of oxygen to break down glucose and create ATP

Question 12

where does cellular respiration occur

Answer 12

Mitochondria

Question 13

what are the three parts of aerobic respiration

Answer 13

glycolysis, Krebs cycle, electron transport chain

Question 14

describe glycolysis

Answer 14

anaerobic, produces two pyruvate‘s, And produces to ATP

Question 15

what is a pyruvate

Answer 15

A six carbon glucose broken in half into two 3 carbon molecules

Question 16

how many ATP are produced in the Krebs cycle

Answer 16

2

Question 17

how many ATP are produced in the electron transport chain

Answer 17

32-34

Question 18

how many ATP can be produced from one molecule of glucose

Answer 18

38

Question 19

what is the equation for cellular respiration

Answer 19

c6h12o6 + 6o2 > 6co2 + 6h2o + ATP

Question 20

what is fermentation

Answer 20

an anaerobic process that allows glycosis to continue when oxygen isn’t available

Question 21

what are the two types of fermentation

Answer 21

lactic acid and alcoholic

Question 22

where can lactic acid fermentation be felt

Answer 22

muscles

Question 23

what is produced an alcoholic fermentation

Answer 23

ethyl alcohol, co2, single called organisms

Question 24

what three factors affect photosynthesis

Answer 24

temperature, light intensity, and water availability

Question 25

what is chemosynthesis

Answer 25

organisms thta cant recieve sunlight process og getting energy

Question 26

what are the stacks of thylakoids called

Answer 26

grana

Question 27

what is the stroma

Answer 27

fluid portion of the matrix

Question 28

how does carbon dioxide enter a plant and oxygen leave the plant

Answer 28

through the stomata

Question 29

how does water enter a plant

Answer 29

through the roots, capillary action

Question 30

what are the products of photoysnthesis

Answer 30

glucose and oxygen

Question 31

describe the glycosis stage

Answer 31

no oxygen required, it produces 2 pyruvates

Question 32

describe the krebs cycle

Answer 32

requires oxygen, makes 2 ATP, co2 is given off

Question 33

describe the electron transport chain

Answer 33

requires oxygen, makes 34 ATP, h2o is given off

Question 34

what are the 3 parts to ATP

Answer 34

adenine, ribose, and three phosphate groups

Question 35

when does ATP become ADP

Answer 35

when a cell uses energy

Question 36

what happens in alcoholic fermentation

Answer 36

glycosis splits glucose and the products enter fermentation
