Photosynthesis/Cellular Respiration Quiz

Question 1

What is the Light Dependent Phase (LDP)?

Answer 1

The first phase of photosynthesis that converts light into chemical energy (ATP and NADPH)

Question 2

Where does the Light Dependent Phase take place?

Answer 2

It takes place in the Thylakoid Membranes (or Grana) of the Chloroplasts

Question 3

What is the Light Independent Phase (LIP)?

Answer 3

The second and last phase of photosynthesis in which the converted chemical energy (ATP and NADPH) are synthesized into Carbohydrates (Glucose)

Question 4

Where does the Light Independent Phase take place?

Answer 4

It takes place in the Stroma of the Chloroplast

Question 5

How are the two phases of Photosynthesis linked? (LDP and LIP)

Answer 5

These two phases are linked due to the LDP converting light energy into ATP and NADPH, which is then converted to Carbohydrates (Glucose) through the LIP

Question 6

What is the Chemical Equation for Photosynthesis?

Answer 6

(6)CO2 + (6)H2O -> C6H12O6 + (6)02

Question 7

What is the primary energy used to drive Photosynthesis?

Answer 7

Light energy from the sun

Question 8

Which molecule (pigments) capture light energy?

Answer 8

Chlorophyll

Question 9

Where in a plant cell does Photosynthesis take place?

Answer 9

The Chloroplast

Question 10

What form of energy is light energy being converted into through Photosynthesis?

Answer 10

Carbohydrates (Glucose) as food for the plant, along with Oxygen as waste released into the atmosphere

Question 11

How many membranes surround a chloroplast?

Answer 11

Two membranes

Question 12

Where is the site of Photosynthesis?

Answer 12

In the leaves of the plant

Question 13

Where does the Calvin Cycle take place, resulting in sugar production?

Answer 13

In the Stroma of the Chloroplast

Question 14

What is the difference between Stroma and a Stoma?

Answer 14

Stroma is colorless fluid that surrounds Grana (thylakoid stacks) within the Chloroplast. A Stoma is a pore-like opening on the underside of the leaf.

Question 15

What other molecular-level things are produced through Photosynthesis?

Answer 15

Electrons and Hydrogen ions (e- and H+ ions)

Question 16

What is the “Calvin Cycle”?

Answer 16

A fancy name for the Light Independent Cycle (LIP).

Question 17

Why does Photosynthesis make plants green?

Answer 17

This is due to the Chlorophyll refusing to absorb green wavelengths of white light, resulting in them being transferred to the plant’s physical appearance instead.

Question 18

Grana or Gana?

Answer 18

Grana. It’s Grana. Dumbass.

Question 19

Stoma or Stroma?

Answer 19

Trick question! They’re two separate things, so both.

Question 20

What is the ATP/ADP cycle?

Answer 20

ATP breaks off the 3rd phosphate group (ENERGY RELEASED), helping to form ADP, which then absorbs the energy back in to form ADP, and so on.

ATP -> ENERGY (phosphate) RELEASED! -> ADP -> ENERGY (phosphate) ABSORBED! -> ATP

Question 21

What is the difference between ATP and ADP?

Answer 21

ATP has all phosphate groupings intact, while ADP contains a lone phosphate group. ATP also holds more stored energy.

Question 22

Which group contains more stored energy and why? ATP or ADP? Where is the energy stored?

Answer 22

ATP contains more energy due to it’s higher phosphate amount, energy is stored within the (3) phosphate groups.

Question 23

What are the parts of ATP/ADP?

Answer 23

ATP - (1) Adenine molecule, (1) Ribose molecule, (3) Phosphate molecules

ADP - (1) Adenine molecule, (1) Ribose molecule, (2) Phosphate groups, (1) Lone Phosphate group

Question 24

What type of macromolecule is ATP & ADP?

Answer 24

They are both Nucleic Acids

Question 25

Where is energy stored in ATP?

Answer 25

It is stored in the bond that is found between the 2nd and 3rd phosphate groups.

Question 26

What happens when a cell requires energy?

Answer 26

It breaks off it’s 3rd ATP phosphate group from the molecule, which then releases energy. Whatever is left over is turned into Adenosine Diphosphate or ADP.

Question 27

What is the Mitochondria made of?

Answer 27

The Mitochondria consists of an Outer Membrane, Inner Membrane, Cristae, Matrix, and DNA.

Question 28

What simple sugar is broken down in the Mitochondria?

Answer 28

Glucose (sugar) for Cellular Respiration

Question 29

By what process is Glucose broken down?

Answer 29

Aerobic Cellular Respiration

Question 30

Where does Glucose come from for organisms that cannot photosynthesize?

Answer 30

It is made by our body through eating food and absorbing nutrients.

Question 31

What is the formula for cellular respiration?

Answer 31

C6H12O6 + O2 -> CO2 + H2O (unbalanced)

C6H12O6 + 6O2 -> 6CO2 +6H2O

Question 32

What are the 3 basic steps of Cellular Respiration?

Answer 32

1. Glycolysis
2. Krebs Cycle (Citric Acid Cycle)
3. The Electron Transport Chain

Question 33

What happens in Glycolysis and where does it take place?

Answer 33

Glucose is split for it’s energy to be captured into ATP Pyruvate. It occurs in the Cytoplasm.

Question 34

What happens in the Krebs Cycle and where does it take place?

Answer 34

Absorbs Pyruvate formed from Glycolysis and produces 3 things: Carbon dioxide, a small amount of ATP, and NADH + FADH. It occurs in the Mitochondria.

Question 35

What happens in The Electron Transport Chain and where does it take place?

Answer 35

It finally breaks down glucose and produces sugar in the form of ATP, to be absorbed as nutrients. It takes place in the mitochondria

Question 36

True or false: Glycolysis occurs outside of the mitochondria

Answer 36

TRUE

Question 37

What does the extra electron at the end of the electron transport system become?

Answer 37

36
