Photosynthesis

Question 1

where do autotrophs get their energy

Answer 1

light

Question 2

where do heterotrophs get their energy

Answer 2

food

Question 3

what is the function of ATP in our cells

Answer 3

The ATP molecule releases chemical energy whenever a bond holding a phosphate group to the molecule is broken

Question 4

where in a cell is ATP produced

Answer 4

mitochondria

Question 5

Does ADP have stored chemical energy usable for the cell

Answer 5

No

Question 6

What is the difference between ATP and ADP

Answer 6

ATP- adenine,ribose, and 3 phosphate groups

ADP- adenine, ribose, and 2 phosphate groups

Question 7

Create an analogy for the difference between ATP and ADP

Answer 7

ATP- full on flashlight

ADP- dim flashlight

Question 8

Define photosynthesis

Answer 8

light energy to chemical energy of glucose

Question 9

Equation of photosynthesis

Answer 9

(reactants) 6CO2 + 6H2O+ light = (products) C6H12O6+ O2

Question 10

What process converts light energy into chemical energy of glucose

Answer 10

photosynthesis

Question 11

Where in the chloroplast does the light dependent reaction occur

Answer 11

thykloid

Question 12

Where in the chloroplast does the light independent reaction occur

Answer 12

stroma

Question 13

What are the two reactants of photosynthesis

Answer 13

6CO2 + 6H2O (carbon dioxide and water)

Question 14

What are the two products of photosynthesis

Answer 14

C6H12O6+ O2 (glucose and oxygen)

Question 15

What is the main function of pigments inside the chloroplasts

Answer 15

to trap light energy

Question 16

What photosynthetic pigments do plants reflect

Answer 16

green

Question 17

What is the function of NAPDH

Answer 17

high energy carrier

Question 18

How would photosynthesis be affected if there were a shortage of NADP in the cells of plants

Answer 18

plants would have less energy

Question 19

What are the reactants and products of the light dependent reaction

Answer 19

R- water and light

P- ATP, NAPDH, and oxygen

Question 20

What are the reactants and products if the light independent reaction

Answer 20

R-ATP, NAPDH, and carbon dioxide

P- Glucose and water

Question 21

What two high energy carrier molecules are made during the light dependent reaction and used in the light independent reaction

Answer 21

ATP and NADPH

Question 22

Why do plants need to make glucose

Answer 22

it is its source of energy

Question 23

In what form do plants store their extra glucose

Answer 23

cellulose in their cell wall

Question 24

Where does the hydrogen come from that plants use to make glucose

Answer 24

water

Question 25

Where does the oxygen come from that plants give off as a waste gas

Answer 25

carbon dioxide

Question 26

Where does the carbon come from that is used to make glucose

Answer 26

it comes from CO2

Question 27

How does the structure of a leaf help to increase the rate of photosynthesis

Answer 27

its thin and it has a stomata

Question 28

Would the concentration of carbon dioxide increase or decrease if the plant was put into darknesss

Answer 28

decrease

Question 29

What are the three primary factors that affect the rate of photosynthesis?

Answer 29

temperature, light, water

Question 30

Compare and contrast at least three differences between the light dependent and the light independent reaction of photosynthesis

Answer 30

Compare- both contribute to photosynthesis and need each other to complete the process
Contrast- (dependent) need light energy, need H2O, and give off NADPH and ATP (independent) need NADPH and ATp, need CO2, and give off glucose
