Photosynthesis

Question 1

Photosynthesis is responsible for..

Answer 1

almost all the planet’s energy resources

Question 2

What is the site of photsynthesis

Answer 2

Chloroplasts

Question 3

Three membranes of the chloroplast are:

Answer 3

• Outer
  -Inner
  -Thylakoid

Question 4

Three compartments of the chloroplast are:

Answer 4

• Intermembrane space
  -Stroma
  -Thylakoid space

Question 5

Light reactions take place on the

Answer 5

thylakoid membrane

Question 6

Carbon fixations occurs in the

Answer 6

stroma

Question 7

Photosystems capture

Answer 7

light energy

Question 8

What are photosystems

Answer 8

Protein complexes that contain chlorophyll in the thylakoid membrane

Question 9

What absorbs light energy

Answer 9

Chlorophyll

Question 10

Due to the photosystem structure,

Answer 10

the light energy absorbed by chlorophyll results in movement of high energy electrons

Question 11

The photosynthetic electron transport chain

Answer 11

Chlorophyll in the photosystems capture light energy and convert it to chemical energy. These high energy electrons move through the photosynthetic electron transport chain

Question 12

In the light reactions, water has been split. What else has been produced?

Answer 12

Oxygen, ATP and NADPH

Question 13

NADPH

Answer 13

Nicotinamide adenine dinucleotide phosphate

Question 14

In the calvin cycle or carbon fixation, what happens?

Answer 14

The ATP and NADPH produced in the light reactions are used to fix carbon dioxide and produce carbohydrate

Question 15

The output of the calvin cycle is..

Answer 15

a 3 carbon sugar that, when combined with another 3 carbon sugar, is converted to glucose

Question 16

Plant cells break down..

Answer 16

glucose from photosynthesis in the mitochondria using cellular respiration

Question 17

Input of photosynthesis

Answer 17

Light, water and carbon

Question 18

Output of photosynthesis

Answer 18

Glucose and oxygen

Question 19

The ATP and NADPH produced in light reactions are only used in..

Answer 19

the calvin cycle

Question 20

What are the energy supply in plants and animals

Answer 20

Glucose and ATP, ATP Synthase

Question 21

Both animals and plants breakdown glucose in cellular respiration to

Answer 21

generate ATP

Question 22

Animals must have an external source of

Answer 22

glucose

Question 23

Plants generate glucose during photosynthesis and then..

Answer 23

break this down during respiration

Question 23

Almost all glucose on earth has directly or indirectly come from..

Answer 23

photosynthesis

Question 24

ATP is generated in both

Answer 24

respiration and photosynthesis

Question 24

ATP generation requires a

Answer 24

proton gradient across a membrane in both the chloroplast and mitochondrion

Question 24

Mitochondria and chloroplasts both contain DNA, ribosomes and are able to make

Answer 24

proteins

Question 25

ATP synthase is responsible for

Answer 25

ATP generation in both processes
