Test 10/30

Question 1

Know what the ATP molecule looks like and where a bond is broken to make ADP

Answer 1

Adenosine P P / P

Ribose

Question 2

What gas is given off by plants during photosynthesis

Answer 2

Oxygen

Question 3

What is the overall reaction of photosynthesis

Answer 3

6Co2 + 6H2O —> c6 h12 o6 + 6o2

light

Question 4

What are the light absorbing molecules in plants called

Answer 4

Chlorophyll

Question 5

Why do plants have many different pigments

Answer 5

Because they absorb different spectrums and wavelengths to get the maximum amount of energy in different weather

Question 6

What region of the visible spectrum of light is absorbed well by chlorophyll

Answer 6

Everything but green

Question 7

What are stomata

Answer 7

They are openings in plants leaves to intake carbon dioxide and release oxygen

Question 8

Why do plants need stomata for photosynthesis

Answer 8

Carbon dioxide goes in through the stomata and without it photosynthesis wouldn’t occur

Question 9

Know what a chloroplast is and grana/granum, stroma, pigment, thylakoid

Answer 9

Grana/granum: short stack
Thylakoid: pancake
Stroma: syrup

Question 10

Where in the chloroplast is chlorophyll found

Answer 10

Thylakoid membranes

Thylakoid

Question 11

What is the location of light dependent reactions

Answer 11

Thylakoid

Question 12

What is the location of the light independent reactions

Answer 12

Stroma

Question 13

What are the products of the light dependent reactions

Answer 13

Oxygen
ATP
NADPH

Question 14

Which of the light dependent products are used in light independent

Answer 14

ATP

NADPH

Question 15

What is the Calvin cycle

Answer 15

Light ad dark reactions use Co2 to make glucose

Question 16

Where does the Calvin cycle take place

Answer 16

Stroma of the chloroplast

Question 17

What are the reactants and products of the Calvin cycle

Answer 17

Co2, ATP, NADPH —> glucose, NADP+, ADP

Question 18

What factors affect the rate of photosynthesis

Answer 18

Light intensity
Water
Temperature
Carbon dioxide

Question 19

How is the suns energy used in photosynthesis

Answer 19

Breaks water bonds

Question 20

The energy in high energy electrons is used for what during electron transport chain

Answer 20

They move down the electron transport chain and the energy moves H+ ions across the membrane

Question 21

Where do the starting materials of cellular respiration originate

Answer 21

Products of photosynthesis

Question 22

What is the difference between aerobic and anaerobic processes

Answer 22

Aerobic: a process with oxygen
36-38 ATP/ takes longer

Anaerobic: process without oxygen
Lactic acid
2 ATP/faster

Question 23

How does the number of ATP compare in aerobic vs anaerobic conditions

Answer 23

Aerobic —> 36-38

Anaerobic —> 2

Question 24

What is the chemical equation that represents cellular respiration

Answer 24

C6 H12 O6 + 6o2 —> 6co2 + 6h20 + energy Krebs
Cycle

Question 25

What are the stages involved in aerobic respiration

Answer 25

Glycolysis Krebs cycle Electron transport chain

Question 26

Name the reactants and products for glycolysis

Answer 26

Glucose —> ATP, NADPH, pyruvic acid

Question 27

Name the two electron carriers I cellular respiration

Answer 27

NADH | FADH2

Question 28

Where are the electrons dropped off

Answer 28

Electron transport chain

Question 29

Why is fermentation necessary in cells

Answer 29

It is necessary because when cells are losing oxygen, they need to be able to release energy still and fermentation allows this

Question 30

When oxygen is present, what is glycolysis followed by

Answer 30

Krebs cycle

Question 31

What does Krebs cycle begin with and what does it produce

Answer 31

Acetyl CoA —> carbon dioxide, high energy electrons, carried by NADH + ATP

Question 32

Where does the ETC and Krebs cycle occur in eukaryotic cells

Answer 32

Mitochondria

Question 33

How many ATP total are produced with glycolysis, Krebs, ETC and the entire process out together

Answer 33

36-38

Question 34

Why do muscles burn after strenuous exercise

Answer 34

Our body needs ATP and when oxygen is used, we need fermentation(anaerobic respiration) to take ATP fast which produces lactic acid and it burns

Question 35

How are photosynthesis and cellular respiration almost opposite processes

Answer 35

Photosynthesis makes what cellular respiration uses and cellular respiration makes what photosynthesis uses (Sunlight goes in) PHOTOSYNTHESIS (out) glucose and oxygen CELL RESP(out) h2o ad Co2

Question 36

In what type of cells does cellular respiration occur

Answer 36

All
