14 photosynthesis

Question 1

A process wherein chemical energy (from the light reactions – ATP and NADPH) and CO2 (from the atmosphere) are used to produce organic compounds (like glucose).

Answer 1

Calvin cycle

Question 2

This is the process of assimilating carbon from a non-organic compound (CO2) and incorporating it into an organic compound (carbohydrates).

Answer 2

Carbon Fixation

Question 3

In process of __________, 3 molecules of CO2 (from the atmosphere) are joined to 3 molecules of RuBP (a 5-carbon sugar) by Rubisco (an enzyme also known as RuBP carboxylase)

Answer 3

carbon fixation

Question 4

3- Phosphoglycerate Molecules
(3-PGA) is the product in ?

Answer 4

carbon fixation

Question 5

In this phase the 3-PGA molecules created through carbon fixation are converted into molecules of simple sugar – glucose.

Answer 5

Reduction

Question 6

The 6 – carbon molecules are reduced by gaining electrons from NADPH.

Answer 6

Reduction

Question 7

Molecular rearranging with the use of ATP. The three 6-carbon molecules will split in half, forming six 3-carbon molecules.

Answer 7

Reduction

Question 8

One of these “extra” 3-carbon G3P/PGAL molecules will exit the cycle and be used to form ½ a glucose molecule.

Answer 8

Reduction

Question 9

Once the Calvin Cycle “turns” twice (well, actually 6 times), those 2 molecules of G3P (a 3-carbon carbohydrate) will combine to form 1 molecule of glucose (a 6-carbon carbohydrate molecule) OR another organic compound.

Answer 9

reduction

Question 10

ATP and NADPH is used in what stage?

Answer 10

reduction

Question 11

glucose is the product in?

Answer 11

reduction

Question 12

It is used to join the 3 molecules of CO2 to 3 molecules of RuBP

Answer 12

rubisco

Question 13

Since this is the Calvin Cycle, we must end up back at the beginning

Answer 13

Regeneration of RuBP

Question 14

The remaining 5 G3P molecules (3-carbons each!) get rearranged (using ATP) to form 3 RuBP molecules (5-carbons each).

Answer 14

Regeneration of RuBP

Question 15

how do regeneration arrange g3p molecules?

Answer 15

using ATP

Question 16

where does G3P come from?

Answer 16

3 turns of calvin cycle

Question 17

TRUE OR FALSE?
Calvin Cycle occurs in the stroma inside the chloroplasts (inside the cell.)

Answer 17

TRUE

Question 18

TRUE OR FALSE?
In the Calvin Cycle, energy and electrons from the Light Reactions (in the form of ATP and NADPH) and carbon dioxide from the atmosphere are used to produce organic compounds.

Answer 18

TRUE

Question 19

Carbon dioxide, ATP, and NADPH are required ________.

Answer 19

reactants

Question 20

Glucose and G3P are produced ________.

Answer 20

products
